Definitions
- the invention relates to a device for in-situ recovery of a hydrocarbonaceous substance.
- the hydrocarbon-containing substance is conveyed from a subterranean deposit while reducing its viscosity.
- the device comprises at least one production pipeline leading out of the deposit.
- Such hydrocarbon-containing substances are known, for example, from "Steam-Injection Strategy and Energetics of Steam-Assisted Gravity Drainage” by ID Gates, 2005, SPE International Thermal Operations and Heavy OiI Symposium, Calgary, Canada, Nov. 1-3, 2005, known.
- Oil sands are a mixture of rocks, clay, sand, water and bitumen or other heavy oils.
- bitumen is to be used as representative of heavy, heavy oils or generally long-chain hydrocarbons, which occurs with a viscosity of typically API 5 ° to 15 ° of storage site.
- the bitumen can be converted into synthetic crude oil by means of further process steps.
- Oil sands are partly located in strata of shallow depth, which are open to the open pit. But there are also large oil sands deposits that are not accessible to the open pit. Typically, the in-situ recovery is made from depths of 60m and below, as the degradation of the overburden then no longer seems worthwhile.
- SAGD Steam Assisted Gravity Drainage
- the SAGD process which heats the bitumen present in a reservoir by superheated steam and makes the reservoir more permeable to vapor pressure, thereby increasing the viscosity of bitumen lowered so that it can be extracted from the deposit in liquid form and faster.
- the change in viscosity of the bitumen occurs through a temperature increase.
- superheated steam is forced through pipelines into the underground storage facility, so that the deposit is heated, and at the same time an overpressure builds up in the deposit.
- Liquid bitumen is transported to the surface through another pipe through the overpressure prevailing in the deposit (see also the seminar on “Unconventional Hydrocarbons” with the topic “Heavy Oils and Ultrasonic Oils” by J. Seim, Freiberg, Germany, January 2001) ).
- the superheated steam can be mixed with a solvent.
- the pipelines for injecting the superheated steam, or the mixture of superheated steam and solvent, are laid essentially parallel to one another, running horizontally within the deposit.
- the injection pipeline and production pipeline typically have a distance of 5 m to 10 m in the vertical direction to each other. However, the distance of the injection pipeline and production pipeline is dependent on the thickness of the deposit. In the horizontal direction, the pipes extend within the deposit on a length of several hundred meters and a few kilometers.
- bitumen Prior to the actual extraction of bitumen from the deposit, it must first be heated to reduce the viscosity of the bitumen present in the sand or rock. During the heating phase, for rapid warming of the deposit, hot steam is applied to both the injection pipeline and the production pipeline for a period of about 3 months. At the end of the heating phase, the bitumen is present in the deposit with a viscosity such that upon further pressurization of the injection pipe with superheated steam and the resulting overpressure in the deposit, liquid bitumen is removed from the production pipe. tion can be promoted to the surface. If sufficient pressure builds up, it is possible to dispense with the installation of lifting oil pumps which bring out the bitumen-water emulsion.
- the currently practiced SAGD method has several technical problems.
- hot steam can escape from the deposit via channels or porous rock layers present in the deposit, a loss which reduces the heating energy introduced into the deposit. Excessive pressures in the deposit can cause blow-outs, especially if the overburden is of small thickness.
- a further problem is the so-called "ringing" within the reservoir, where vapor breakage occurs mostly at the beginning or at the end of the horizontal piece of the parallel vapor injection or production tube, the vapor being a preferred one communicating path between both tubes is sought and undesirable pressure is dissipated, whereby the injected vapor is condensed and conveyed through the production tube as water, whereby the reservoir is supplied with low vapor and thus thermal energy and the efficiency of the process drastically decreases Depending on the conditions of the deposit, it is therefore not possible to increase it as much as possible within the storage facility, for rapid heating of the storage facility.
- the SAGD method requires large amounts of fresh water. The required amount of water is determined by the "Steam to Oil Ratio" (SOR) - sen. Strict environmental regulations in the assisted areas call for a reduction in the "steam to oil ratio" in order to protect the above and below ground water resources.
- Object of the present invention is to provide a device for in-situ recovery of a hydrocarbonaceous substance, in particular to provide a device for conveying heavy oils or bitumen from an oil sands deposit, at least compared to the prior art in such a way is improved that a shortened heating phase can be achieved before the start of the production phase.
- the invention is based on the idea of using an electric heater, which is both inductive and resistive against at least parts of the deposit, for rapid heating of the same.
- the deposit itself acts as a resistive (ohmic) resistance to the at least two electrodes of the heater. At the same time, the deposit is also inductively heated by the electric heater.
- a device for the in situ recovery of a hydrocarbonaceous substance with a reduction in its viscosity from an underground deposit which comprises at least one production pipeline leading out of the reservoir.
- the device furthermore has at least two electrodes which are inductive and resistive to at least parts of the deposit as electrical heating.
- the heating time of the reservoir containing the hydrocarbonaceous substance can be shortened.
- the "steam to oil ratio" can be lowered.
- the apparatus for recovering a hydrocarbonaceous substance according to the invention may additionally have the following features:
- the two electrodes of the electric heater can be formed by at least partially extending in the deposit, substantially vertically oriented electrical conductor. A vertical hole requires little drilling effort.
- electrical conductors which are inductive and resistive to at least parts of the deposit can be introduced into the deposit in a simple and effective manner.
- This device is particularly advantageous if it must be assumed that the permeability decreases with increasing depth, or the permeability is inhomogeneous in the horizontal direction, ie, that there is an inhomogeneous and possibly anisotropic deposit with respect to the permeability and / or porosity.
- the at least two electrodes of the electric heater may be formed by substantially horizontally oriented electrical conductors extending at least partially within the deposit. With electrical conductors running horizontally within the deposit, much of the deposit can be electrically or electrically heated both electrically and inductively.
- the electrodes may be rod-shaped metallic conductors.
- Rod-shaped metallic conductors are particularly simple and inexpensive.
- At least partial sections of the electrodes may have a spatial distance from one another, which decreases with increasing length of the electrodes viewed from a current source.
- the distance decrease can in particular be continuous.
- the spatial distance of the sections of the electrodes can decrease linearly.
- the electrons may extend coaxially in a guide tube, the guide tube being permeable for the targeted deposition of a liquid into parts of the deposit at the corresponding partitions extending for the liquid in the deposit.
- the reservoir can be supplied to liquid in targeted areas, whereby the electrical conductivity of the deposit can be influenced. In this way, the conductivity of the deposit can be ensured, so that a trouble-free function of the electric heater is given.
- the device may have an injection pipeline projecting into the deposit.
- the deposit can be heated firstly by means of the electric heater and secondly by means of, for example, a vapor-assisted heating process. Both methods can synergize synergistically.
- the electrodes may be electrically connected to one another at their end regions remote from the current source by a conductor bridge. By such an electrical connection fertil the reliability of the electrical heating can be improved.
- the injection pipeline and the production pipeline can have pipe sections that run essentially parallel to one another in the deposit, essentially horizontally oriented. Viewed in a section perpendicular to the injection and production pipeline, the electrodes of the electric heater are closed arranged on both sides of the injection and production pipeline. By arranging the electrodes of the electric heater on both sides of the injection and production pipeline, in particular the volume of the storage site which extends in the horizontal direction between the injection or production pipeline can be heated by means of the electric heater. Particularly advantageous can be exploited in this way a larger volume of the deposit. SAGD processes known from the prior art achieve a yield of between 40 and 60% of the bitumen present in the deposit. According to the above-described embodiment, yields of over 70% appear possible.
- At least two of the electrodes of the electric heater can be formed by at least parts of the injection pipeline or the production pipeline.
- the injection pipe and the production pipeline can be acted upon with superheated steam.
- hot steam is typically applied to existing pipelines in the reservoir.
- the combination of such a hot steam-based method with an electric heating method is particularly advantageous because additional hot water is introduced into the deposit by the superheated steam, which increases the electrical conductivity of the deposit.
- a certain electrical conductivity is necessary to carry out an inductive and resistive electrical heating process.
- the synergetic combination of a superheated steam process and an electrical see heating process the efficiency of the combined process can be increased over those of both individual processes.
- the superheated steam can be enriched with an electrolyte, preferably with salt.
- the electrical conductivity of the steam is increased.
- the effectiveness of an inductive and resistive electric heater against at least parts of a deposit is substantially dependent on the electrical conductivity of the deposit.
- the electric heater may be an AC heater.
- AC heating prevents ion migration within the reservoir.
- coking or salting of the injection and / or production pipeline can be avoided in this way.
- FIG. 1 shows a schematic diagram of a device for in-situ recovery of a hydrocarbonaceous substance from an underground reservoir
- Figure 2 shows a cross section through the exploitation of such a deposit
- Figures 3 and 4 a device for in-situ recovery of a hydrocarbonaceous substance with an electric heater as well
- FIG. 5 shows a further embodiment of such a device.
- Figure 1 shows, schematically illustrated, an apparatus for in situ recovery of a hydrocarbonaceous substance from an underground deposit 100 while reducing its viscosity.
- a device may be, for example, an apparatus for recovering bitumen from an oil sands deposit.
- An injection pipeline 101 leads from the earth's surface into the deposit 100.
- a production pipeline 102 leads out of the deposit 100 to the earth's surface.
- Devices are conceivable in which a plurality of injection pipelines 101 and a plurality of production pipelines 102 are used to convey the hydrocarbon-containing substance from the underground deposit 100.
- the deposit 100 may be, in particular, an oil sands deposit or an oil shale deposit from which bitumen or other heavy oils may be recovered.
- the hydrocarbonaceous substance present in the deposit 100 In order to recover the hydrocarbonaceous substance from the deposit 100, the hydrocarbonaceous substance present in the deposit 100 must be reduced in viscosity. For this purpose, at least parts of the deposit 100 must be heated. To heat the storage 100, the injection pipe and the production pipeline 102 are supplied with superheated steam. After a heating time of typically 3 months, the viscosity of the hydrocarbonaceous substance present in the deposit 100 has dropped to such an extent due to the elevated temperature that the substance has become free-flowing. If now the injection pipeline 101 continues to be subjected to water vapor, then due to the overpressure present in the deposit or at least parts of the deposit 100, coking hydrogen-containing substance are conveyed through the production pipeline 102 to the surface.
- the injection pipeline 101 continues to be supplied with superheated steam. Arrived at the surface, the recovered hydrocarbon-containing substance can be subjected to further treatment steps, so that synthetic crude oil can be obtained.
- FIG. 2 shows a cross section through the deposit 100, in which two injection pipes 101, 101 'and two production pipes 102, 102' run.
- the hot steam emanating from the injection pipes 101, 101 ' is shown schematically by arrows.
- the hot steam forms within the deposit 100 steam chambers 201, 201 ', from which the hydrocarbonaceous substance which has become fluid can be conveyed.
- 201 ' extends a dead volume 202 in which the viscosity of the hydrocarbonaceous substance present in the deposit 100 is too high to be conveyed.
- the dead volume 202 of the deposit 100 can not be exploited.
- FIG. 3 shows a device for the in-situ recovery of a hydrocarbonaceous substance from a deposit 100, which has two production pipelines 102, 102 'in addition to two injection pipelines 101, 101' which have horizontally extending tubular parts in the deposit 100.
- the apparatus for in situ recovery of a hydrocarbonaceous substance furthermore has two electrodes 301, 301 'which run in vertical boreholes within the deposit 100.
- the electrodes 301, 301 ' are effective against at least parts of the deposit 100 as inductive and resistive electric heating. Due to the conductivity of at least parts of the deposit 100, in particular of the dead volume 202, this can be resistively heated by current flowing between the two electrodes 301, 301 '.
- the resistive heating effect is by arrows or lines within the deposit 100 indicated.
- the electrodes 301, 301 'in the volumes 303, 303' act as inductive heaters.
- the electrodes 301, 301 ' can be insulated from the ground in areas where they run outside the actual deposit 100 by means of electrical insulations 304, 304'. In this way, the resistive heating power can be introduced into defined regions of the deposit 100.
- the electrodes 301, 301 ' may be, in particular, rod-shaped metallic conductors made of an especially good conductive metal.
- the apparatus shown in FIG. 3 for the in-situ recovery of a hydrocarbon-containing substance can in particular be operated such that the deposit 100 is heated both by superheated steam and by means of the electric heater.
- both the injection pipelines 101, 101 'as well as the production pipelines 102, 102' can be supplied with superheated steam, in addition, the volume of the hydrocarbon-containing substance is to be conveyed, in particular the dead volume 202 by means of the electric heater are heated via the electrodes 301, 301 '. In this way, a shorter heating time can be achieved than if the deposit 100 is heated only by means of electric heating or by steaming.
- Heating may in particular be an AC heater, whereby no ion migration takes place within the deposit 100.
- the heating of the deposit 100 or at least parts of the deposit 100 may result in a decrease in the liquid content of the deposit 100 and thus a decrease in the electrical conductivity of the deposit 100.
- a sinking conductivity of the deposit 100 causes the electrical heater, in particular the resistive mode of action, to lose its effectiveness.
- the hot steam pressed into the deposit 100 with minerals, in particular with Salts to be enriched.
- the conductivity of the deposit 100 can be adjusted in a targeted manner.
- the minerals or salts are added to the superheated steam after it leaves the steam generator. On the other hand, if the bitumen is exploited in one place, no conductivity is required at this point.
- the inductive mechanism of action then causes losses to occur only where there is conductivity, ie the penetration depth expands accordingly and the bitumen residing in the natural conductivity is heated and flows down through the gravity with the naturally occurring reservoir electrolyte.
- the loss mechanism by resistive but also inductive mode of action will be most effective at the electrode first; ie at the beginning of the exploitation, the bitumen is made more fluid there. If the conductivity at the electrode is low, there is no contact between electrode and reservoir; Now, the inductive mechanism comes into play, which is not dependent on the electrical contact between the electrode and the reservoir.
- FIG. 4 shows an apparatus for in situ recovery of a hydrocarbonaceous substance from a deposit 100.

- the electrodes 301, 301 'heat areas 303, 303' which are cylindrical about the injection pipes 101, 101 'extend.
- the dead volume 202 is heated in particular by resistive means.
- FIG. 5 shows an apparatus for in situ recovery of a hydrocarbonaceous substance from a deposit 100.
- the exemplary embodiment shown in FIG. 5 comprises two production pipelines 102, 102 'which lead out of the deposit 100.
- Protruding into the deposit 100 are two electrodes 301, 301 ', which are each arranged in a guide tube 501, 501'.
- the guide tubes 501, 501 ' are accessible from the surface and are additionally electrically insulated from the soil by means of electrical insulations 304, 304' in the parts running outside the deposit or the areas of the deposit 100 to be heated.
- the guide tubes 501, 501 ' are accessible from the surface of the earth for a liquid and have permeable areas in certain areas within the reservoir 100 for the liquid. These may be, for example, porous embodiments of the pipe walls or openings or holes.
- a liquid which is enriched with an electrolyte to improve the conductivity
- the electrical conductivity of the deposit 100 can be adjusted specifically. In this way, the functionality of the electric heater can be ensured.
- the ends of the electrodes 301, 301 ', which are remote from the current source 302 may be short-circuited with an electrical bridge 502.
- bitumen deposit without the use of superheated steam.
- the deposit can only be heated by means of the electric heating by inductive and resistive means, the liquid bitumen present in the production pipeline 102, 102 'can be conveyed by means of a lifting pump. Borrow or acts transported by natural geological overpressure to the earth's surface.
- the reservoir 100 may be supplied with superheated steam at intervals through the production tubing 102, 102 'such that the pressure within the reservoir 100 increases. The overpressure generated in this manner can also be used to extract bitumen from the deposit 100.
- the electrodes 301, 301 ' can furthermore run within the deposit 100 in such a way that they are spaced apart from one another by the current source 302 and decrease with increasing length of the electrodes 301, 301' relative to one another. In particular, a linear decrease of the distance of the electrodes 301, 301 'from each other can take place. It can be avoided in this way that the electric heating power, in particular the resistive electric heating power viewed from the power source 302, at the beginning of the electrodes 301, 301 'is introduced into the deposit 100 or falls into this area.
- the spacing of the electrodes 301, 301 ' may in particular be selected such that a continuous heat output over the length of the electrodes 301, 301', in particular over the length of the portions of the electrodes 301, 301 ', which run within the reservoir 100, taking into account the electrical conductivity of the deposit 100 can be achieved.
- the spacing of the holes can be controlled by well-known measures, for example, a transmitter can be performed in the first bore, wherein the drill bit of the second bore, starting from this transmission signal can determine the distance to the first hole.
