Description

Verfahren zur Förderung von Multiphasengemischen sowie PumpenanlageProcess for conveying multi-phase mixtures and pump system
Die Erfindung betrifft ein Verfahren zur Förderung von Multiphasengemischen, insbesondere Kohlenwasserstoffen aus einem Bohrloch, mit einer Verdrängerpumpe, durch die das Multiphasengemisch gepumpt wird, sowie eine Pumpenanlage mit einer Verdrängerpumpe zur Förderung von Multiphasengemischen mit einer Saugleitung und einem Druckraum, wobei die Saugleitung insbesondere in einem Bohrloch mündet.The invention relates to a method for conveying multi-phase mixtures, in particular hydrocarbons from a borehole, with a positive displacement pump through which the multi-phase mixture is pumped, and a pump system with a positive displacement pump for conveying multi-phase mixtures with a suction line and a pressure chamber, the suction line in particular in one Borehole opens out.
Kohlwasserstoffförderung mit an der Oberfläche, in der Regel in Bohrloch- nähe aufgestellten Multiphasenpumpen, stellt eine wirtschaftliche, ausreichend betriebssichere und funktionierende Technik zur Förderung schwacher Quellen sowie zur Steigerung des Entölungsgrades dar. Multiphasenpumpen an sich sind bekannt, zum Beispiel aus der EP 0 699 276 A1 , auf die vollinhaltlich Bezug genommen wird und deren Offenbarung in die An- meidung aufgenommen wird. Typisch für die Kohlenwasserstoffförderung, beispielsweise Erdöl und Erdgasförderung, sind Druckabsenkungen am Sonnenkopf auf cirka 2 - 5 bar, geringere Kopfdrücke sind in der Regel aufgrund der Volumenexpansion des Gasanteils und dem daraus resultierenden steigenden Bauaufwand wenig wirtschaftlich.Hydrocarbons production with multi-phase pumps installed on the surface, usually near the borehole, is an economical, sufficiently reliable and functional technology for promoting weak sources and for increasing the degree of de-oiling. Multi-phase pumps are known per se, for example from EP 0 699 276 A1, to which reference is made in full and the disclosure of which is incorporated into the avoidance. Typical for hydrocarbon production, such as crude oil and natural gas production, are pressure drops at the sun's head to around 2 - 5 bar, lower head pressures are generally not very economical due to the volume expansion of the gas component and the resulting increasing construction costs.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren und eine Pumpenanlage bereit zu stellen, mit der die Abförderung des Multiphasengemisches verbessert und gleichzeitig der erforderliche Bauaufwand für die Pumpenanlage begrenzt wird.Based on this prior art, the invention has for its object to provide a method and a pump system with which the removal of the multi-phase mixture is improved and at the same time the construction work required for the pump system is limited.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass druckseitig ein Teilflüssigkeitsstrom aus dem Hauptförderstrom abgezweigt und zu der Hochdruckseite zumindest einer Strahlpumpe geleitet wird, die als Förderhilfsmittel auf der Saugseite der Verdrängerpumpe angeordnet ist, bzw. dass eine Speiseleitung den Druckraum der Verdrängerpumpe mit der Hochdruckseite zumindest einer Strahlpumpe verbindet und die Strahlpum- pe einlassseitig in Förderrichtung der Verdrängerpumpe angeordnet ist.According to the invention, this object is achieved in that a partial liquid flow is branched off from the main delivery flow on the pressure side and directed to the high pressure side of at least one jet pump which is arranged as a conveying aid on the suction side of the positive displacement pump, or in that a feed line connects the pressure chamber of the positive displacement pump with the high pressure side of at least one Jet pump connects and the jet pump is arranged on the inlet side in the conveying direction of the displacement pump.
Die zum Antrieb der Strahlpumpe verwendete Druckflüssigkeit zirkuliert zwischen der Strahlpumpe und der Verdrängerpumpe, insbesondere als Multiphasenpumpe ausgebildet, ohne dass eine bleibende Kontamination des Fördergemisches auftritt. Darüber hinaus ist die Energieversorgung der Strahlpumpe sichergestellt, ohne dass eine externe Energiequelle, insbesondere ein hydraulische Energiequelle zur Verfügung gestellt werden muss.The hydraulic fluid used to drive the jet pump circulates between the jet pump and the positive displacement pump, in particular in the form of a multi-phase pump, without permanent contamination of the delivery mixture occurring. In addition, the energy supply to the jet pump is ensured without the need to provide an external energy source, in particular a hydraulic energy source.
Durch eine geeignete Auslegung der Strahlpumpe lässt sich erreichen, dass die Verdrängerpumpe mit einem moderaten Vordruck, der beispielsweise 2 bar beträgt, gespeist wird, so dass die Abförderung des Multiphasengemisches verbessert und das freie Gasvolumen gleichzeitig begrenzt wird. Dadurch kann sich der Bauaufwand der Verdrängerpumpe verringern, was insgesamt die Kosten reduziert.With a suitable design of the jet pump it can be achieved that the positive displacement pump is supplied with a moderate admission pressure, which is, for example, 2 bar, so that the removal of the multi-phase mixture is improved and the free gas volume is limited at the same time. This can reduce the construction effort of the positive displacement pump, which overall reduces the costs.
Vorteilhafterweise ist die Strahlpumpe im oder am Bohrloch angeordnet, sofern das Multiphasengemisch aus einer Kohlwasserstoffquelle gefördert wird, um das Ansaugen der Kohlenwasserstoffe zu erleichtern. Alternativ ist es möglich, dass die Strahlpumpe innerhalb der Saugleitung angeordnet ist.The jet pump is advantageously arranged in or on the borehole if the multi-phase mixture is conveyed from a hydrocarbon source in order to facilitate the suction of the hydrocarbons. alternative it is possible that the jet pump is arranged within the suction line.
Multiphasengemische zeichnen sich durch eine hohe Veränderlichkeit in ih- rer Zusammensetzung aus, wobei es sich um ein Vielstoffgemisch handelt, das in mehreren Phasen vorliegen kann. Die Zusammensetzung kann sich von nahezu 100 % Flüssigphase auf nahezu 100 % Gasphase verändern, wobei auch große Anteile von Feststoffen in einem Multiphasengemisch vorkommen können. Um eine ausreichende Kühlung und Abdichtung der Verdrängerpumpe zu bewirken, ist es vorgesehen, dass in der Verdrängerpumpe eine Separation von Gasphase und Flüssigkeitsphase durchgeführt und der Teilflüssigkeitsstrom zu der Strahlpumpe aus der separierten Flüssigkeitsphase abgezweigt wird. Somit wird zum Betreiben der Strahlpumpe eine Flüssigkeit verwendet, die nur noch einen geringen Gasanteil aufweist und der Flüssigkeitsphase des geförderten Produktes entspricht. Eine Veränderung bzw. Kontamination des Förderproduktes durch den Einsatz des abgezweigten Teilflüssigkeitsstromes als Energieträger für die Strahlpumpe findet somit nicht statt, und die Verdrängerpumpe wird stets mit einem Flüssigkeitsanteil saugseitig versorgt, so dass eine hinreichende Schmie- rung, Kühlung und Abdichtung der Verdrängerpumpe stattfindet.Multi-phase mixtures are characterized by a high variability in their composition, which is a multi-substance mixture that can exist in several phases. The composition can change from almost 100% liquid phase to almost 100% gas phase, whereby large proportions of solids can also occur in a multi-phase mixture. In order to achieve sufficient cooling and sealing of the displacement pump, it is provided that the gas pump and the liquid phase are separated in the displacement pump and the partial liquid flow to the jet pump is branched off from the separated liquid phase. Thus, a liquid is used to operate the jet pump, which only has a small gas fraction and corresponds to the liquid phase of the product being conveyed. There is therefore no change or contamination of the conveyed product through the use of the branched-off partial liquid flow as an energy source for the jet pump, and the positive displacement pump is always supplied with a liquid portion on the suction side, so that there is sufficient lubrication, cooling and sealing of the positive displacement pump.
Eine Weiterbildung der Erfindung sieht vor, dass ein Teilvolumenstrom der separierten Flüssigkeitsphase über eine Kurzschlussleitung der Saugseite der Verdrängerpumpe dosiert zugeführt wird, also dass die Zuleitung nicht ausschließlich über die Strahlpumpe erfolgt, sondern über eine vorzugsweise innerhalb des Verdrängerpumpengehäuses angeordnete Kurzschlussleitung erfolgt, wodurch sich die Gefahr eines Trockenlaufes der Verdrängerpumpe reduzieren lässt. Eine Weiterbildung der Erfindung sieht vor, dass nach der Abzweigung des Teilflüssigkeitsstromes dieser durch einen zusätzlichen Separator zur Trennung von Gasphase und Flüssigkeitsphase geleitet wird, falls die Separation innerhalb der Verdrängerpumpe nicht ausreichend war. Durch den zusätzli- chen Separator wird sichergestellt, dass eine weitestgehend von der Gasphase befreite Flüssigkeitsphase der Strahlpumpe als Druckflüssigkeit und Energieträger zugeleitet wird.A further development of the invention provides that a partial volume flow of the separated liquid phase is metered in via a short-circuit line on the suction side of the positive displacement pump, i.e. that the supply line is not exclusively via the jet pump, but via a short-circuit line preferably arranged within the positive displacement pump housing, which increases the risk a dry running of the positive displacement pump can be reduced. A further development of the invention provides that after the partial liquid flow has branched off, it is passed through an additional separator for separating the gas phase and liquid phase if the separation within the displacement pump was not sufficient. The additional separator ensures that a liquid phase largely freed from the gas phase is fed to the jet pump as pressure fluid and energy source.
Um ein ausreichend hohes Druckniveau, insbesondere ein konstantes Druckniveau bereit zu stellen, ist zwischen der Verdrängerpumpe und der Strahlpumpe eine Druckerhöhungspumpe vorgesehen, durch die der Förderdruck erhöht wird.In order to provide a sufficiently high pressure level, in particular a constant pressure level, a pressure booster pump is provided between the displacement pump and the jet pump, by means of which the delivery pressure is increased.
Die erfindungsgemäße Pumpenanlage sieht vor, dass eine Speiseleitung den Druckraum der Verdrängerpumpe mit der Hochdruckseite zumindest einer Strahlpumpe verbindet, wobei die Strahlpumpe einseitig in Förderrichtung der Verdrängerpumpe angeordnet ist, um die Verdrängerpumpe mit einem moderaten Vordruck zu speisen. Von der Druckseite der Verdrängerpumpe wird also ein Teilflüssigkeitsstrom zur Hochdruckseite einer oder mehrerer Strahlpumpen, die als Förderhilfsmittel eingesetzt werden, geleitet, was eine besonders wirtschaftliche Druckerhöhung saugseitig bewirkt. Anders als bei aktiven Komponenten zur Erhöhung des Vordruckes, bei denen mechanische Teile eine Druckerhöhung bewirken, beispielsweise in Gestalt von Down-Hole-Pumpentechnologien, wie Beam Pump, ESP, PCP oder SSP, sind Strahlpumpen extrem einfach aufgebaut und besitzen keine bewegten Teile. Insbesondere aufgrund der mitunter hohen abrasiven Eigenschaften des geförderten Multiphasengemisches ist der Verzicht auf mechanische Komponenten vorteilhaft. Aufgrund des geringen Wartungsaufwandes sind die Anlagen zuverlässiger und kostengünstiger, zumal im Bereich eines Bohrloches die Zugänglichkeit eingeschränkt und eine Reparatur sehr aufwendig ist. Dies führt zu langen Stillstandszeiten und zu Wirtschaftlichkeitsproblemen bei den Anlagebetreibern. Vorteilhafterweise sind innerhalb des Verdrängerpumpengehäuses Separationseinrichtungen zur Trennung von Gasphase und Flüssigkeitsphase im Druckraum ausgebildet, wodurch die Gasphase des Multiphasengemisches von der Flüssigkeitsphase separiert wird und lediglich die Flüssigkeitsphase zum Antreiben der Strahlpumpe verwendet wird.The pump system according to the invention provides that a feed line connects the pressure chamber of the positive displacement pump with the high pressure side of at least one jet pump, the jet pump being arranged on one side in the direction of delivery of the positive displacement pump in order to feed the positive displacement pump with a moderate admission pressure. A partial liquid flow is thus directed from the pressure side of the displacement pump to the high pressure side of one or more jet pumps, which are used as delivery aids, which results in a particularly economical pressure increase on the suction side. In contrast to active components for increasing the upstream pressure, in which mechanical parts increase the pressure, for example in the form of down-hole pump technologies such as beam pump, ESP, PCP or SSP, jet pumps are extremely simple and have no moving parts. In particular due to the sometimes high abrasive properties of the conveyed multi-phase mixture, the omission of mechanical components is advantageous. Due to the low maintenance requirements, the systems are more reliable and cheaper, especially in the area of one Borehole limited accessibility and repair is very expensive. This leads to long downtimes and economic problems for the plant operators. Separation devices for separating the gas phase and liquid phase in the pressure chamber are advantageously formed within the displacement pump housing, as a result of which the gas phase of the multi-phase mixture is separated from the liquid phase and only the liquid phase is used to drive the jet pump.
Um sicherzustellen, dass bei einer besonders langen Ausgestaltung der Speiseleitung ein gewisser Flüssigkeitsumlauf zur Abdichtung, Schmierung und Kühlung der Verdrängerpumpe vorhanden ist, ist eine Kurzschlussleitung von der Druckraumseite zur Saugseite der Verdrängerpumpe zur dosierten Zuführung der separierten Flüssigkeitsphase vorgesehen.In order to ensure that there is a certain liquid circulation for sealing, lubricating and cooling the positive displacement pump in the case of a particularly long configuration of the feed line, a short circuit line is provided from the pressure chamber side to the suction side of the positive displacement pump for the metered supply of the separated liquid phase.
Zur verbesserten Trennung von Flüssigkeitsphase und Gasphase ist in der Speiseleitung ein Zusatzseparator vorgesehen, von dem Zusatzseparator eine Rückführleitung der separierten Gasphase zur Druckleitung der Verdrängerpumpe führt, so dass die Gasphase zusammen mit dem übrigen Förderprodukt zur Weiterverarbeitung abgeführt werden kann.To improve the separation of the liquid phase and gas phase, an additional separator is provided in the feed line, from the additional separator a return line of the separated gas phase leads to the pressure line of the positive displacement pump, so that the gas phase can be removed for further processing together with the other conveyed product.
In der Speiseleitung ist eine Druckerhöhungspumpe angeordnet, so dass die separierte Flüssigkeitsphase einen erhöhten Energiegehalt aufweist.A pressure booster pump is arranged in the feed line, so that the separated liquid phase has an increased energy content.
Es hat sich als vorteilhaft herausgestellt, dass die Verdrängerpumpe als eine Schraubenspindelpumpe ausgebildet ist, da Schraubenspindelpumpen Mul- tiphasengemische, insbesondere mit einem hohen Anteil an abrasiven Stoffen und stark wechselnden Gasanteilen, zuverlässig fördern und Vorteile bei der Verfügbarkeit bieten. Aus Montagegründen ist es vorteilhaft, dass die Strahlpumpe im oder am Bohrloch an dem Ende der Saugleitung angeordnet ist, alternativ ist es möglich, dass die Strahlpumpe an einem anderen Ort angeordnet ist, bei- spielsweise in der Saugleitung näher an der Verdrängerpumpe oder aber in einem Bohrloch entfernt von der Saugleitung. It has proven to be advantageous that the positive displacement pump is designed as a screw pump, since screw pumps reliably deliver multi-phase mixtures, in particular with a high proportion of abrasive substances and strongly changing gas components, and offer advantages in terms of availability. For reasons of assembly, it is advantageous that the jet pump is arranged in or at the borehole at the end of the suction line, alternatively it is possible for the jet pump to be arranged at a different location, for example in the suction line closer to the displacement pump or in one Drill hole away from the suction line.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der einzigen Figur erläutert, in der der prinzipielle Aufbau einer Pumpenanlage dargestellt ist.An exemplary embodiment of the invention is explained below with reference to the single figure, in which the basic structure of a pump system is shown.
Kern der Pumpenanlage ist eine Verdrängerpumpe 1 , die als Multiphasen- pumpe vorgesehen und vorteilhafterweise als Schraubenspindelpumpe ausgebildet ist. Saugseitig ist eine Saugleitung 10 angeordnet, die in ein Bohrloch 3 mündet. Am Ende der Saugleitung 10 innerhalb des Bohrloches ist eine Strahlpumpe 2 angeordnet, die so ausgerichtet ist, dass die Hochdruckseite der Strahlpumpe 2 in Richtung der Saugseite der Verdrängerpumpe 1 gerichtet ist, um die Verdrängerpumpe 1 mit einem Vordruck zu beaufschlagen.The core of the pump system is a positive displacement pump 1, which is provided as a multi-phase pump and is advantageously designed as a screw pump. A suction line 10 is arranged on the suction side and opens into a borehole 3. At the end of the suction line 10 within the borehole, a jet pump 2 is arranged, which is oriented in such a way that the high-pressure side of the jet pump 2 is directed in the direction of the suction side of the positive displacement pump 1 in order to apply a pre-pressure to the positive displacement pump 1.
Die Strahlpumpe 2, vorzugsweise als eine Jetpumpe ausgebildet, wird über einen Teilflüssigkeitsstrom 13 gespeist, der druckseitig von der Verdrängerpumpe 1 abgezweigt wurde. Über eine Speiseleitung 7 wird der Teilflüssigkeitsstrom 13 der Hochdruckseite der Strahlpumpe 2 zugeleitet.The jet pump 2, preferably in the form of a jet pump, is fed via a partial liquid stream 13, which was branched off from the displacement pump 1 on the pressure side. The partial liquid flow 13 is fed to the high-pressure side of the jet pump 2 via a feed line 7.
Der Teilflüssigkeitsstrom 13 wird aus einem separierten Multiphasenge- misch abgezweigt, wobei innerhalb der Verdrängerpumpe eine Separation der Flüssigkeitsphase und der Gasphase stattfindet. Eine vorbestimmte Menge an Flüssigkeitsphase wird druckseitig von der Verdrängerpumpe 1 abgezweigt, das übrige Förderprodukt wird durch eine Druckleitung 1 1 der weiteren Verarbeitung zugeleitet. Zur weiteren Separierung von Gasphase und Flüssigkeitsphase des Multiphasengemisches ist ein Zusatzseparator 4 zwischengeschaltet, von dem eine Rückführleitung 14 zur Druckleitung 11 führt, wobei die nicht benötigte Flüssigkeitsphase oder die zusätzliche separierte Gasphase der Druckleitung 1 1 zugeleitet wird. Optional ist eine Druckerhöhungspumpe 5 in der Speiseleitung 7 vorgesehen, um das Energieniveau der Druckflüssigkeit für die Strahlpumpe 2 zu erhöhen.The partial liquid stream 13 is branched off from a separated multiphase mixture, the liquid phase and the gas phase being separated within the displacement pump. A predetermined amount of liquid phase is branched off on the pressure side from the positive displacement pump 1, the rest of the conveyed product is fed through a pressure line 11 for further processing. For further separation of the gas phase and liquid phase of the multi-phase mixture, an additional separator 4 is interposed, from which a return line 14 leads to the pressure line 11, the liquid phase which is not required or the additional separated gas phase being fed to the pressure line 11. A pressure booster pump 5 is optionally provided in the feed line 7 in order to increase the energy level of the pressure fluid for the jet pump 2.
Ebenfalls ist optional eine Kurzschlussleitung 15 vorgesehen, über die ein Teilstrom aus der separierten Flüssigkeit saugseitig der Verdrängerpumpe 1 zugeführt wird, um stets eine hinreichende Kühlung und Schmierung zu gewährleis-ten. Die Kurzschlussleitung 15 kann auch innerhalb des Verdrängerpumpengehäuses ausgebildet sein.A short-circuit line 15 is also optionally provided, via which a partial flow from the separated liquid is fed to the positive displacement pump 1 on the suction side in order to always ensure adequate cooling and lubrication. The short-circuit line 15 can also be formed within the positive displacement pump housing.
Durch die Zirkulation eines Teilflüssigkeitsstromes innerhalb der Pumpenanlage wird ein Förderhilfsmittel bereit gestellt, so dass die Verdrängerpumpe das Multiphasengemisch aufgrund des vorhandenen Vordruckes besser ab- fördern kann, wobei die Volumenexpansion des Gasanteils begrenzt und der daraus resultierende steigende Bauaufwand vermieden wird. Der einfache Aufbau der Strahlpumpe ohne bewegte Teile vermindert den baulichen Aufwand und vermeidet Stillstandszeiten aufgrund von Reparaturen, die durch den Verschleiß mechanischer Bauelemente entstehen. Darüber hinaus wird als Druckflüssigkeit kein externer Energieträger verwendet, der mit dem Förderprodukt vermischt wird, was bei der nachträglichen Verarbeitung des Förderproduktes hinderlich sein kann. Darüber hinaus steht in vielen Fällen keine separate Druckflüssigkeit zur Verfügung, so dass eine stete Einsetzbarkeit der Pumpenanlage gewährleistet ist.The circulation of a partial liquid flow within the pump system provides a delivery aid so that the positive displacement pump can better discharge the multi-phase mixture due to the existing admission pressure, limiting the volume expansion of the gas portion and avoiding the resulting increase in construction costs. The simple construction of the jet pump without moving parts reduces the construction effort and avoids downtimes due to repairs caused by the wear of mechanical components. In addition, no external energy source is used as the pressure fluid, which is mixed with the conveyed product, which can be a hindrance to the subsequent processing of the conveyed product. In addition, in many cases there is no separate hydraulic fluid available, so that the pump system can always be used.
Selbstverständlich können von einer Verdrängerpumpe 1 mehrere Strahlpumpen 2 gespeist werden. Of course, several jet pumps 2 can be fed by one displacement pump 1.
