The present invention relates generally to for well bore (pit shaft) and equipment and the method relevant to the nytron the production of material.The present invention particularly but do not relate to uniquely for the interlayer in well and separate well bore equipment and the method that (zonal isolation) provides gravel to fill.

This part intention is introduced the various aspects of the art, and these aspects may be relevant with the exemplary embodiment of present technique.Believe that this discussion helps to provide a framework to promote the better understanding to the concrete aspect of present technique.Therefore, it should be understood that this part should read from this angle, and needn't be as the explanation to prior art.

The production of hydrocarbon (as gentle in oil) has been carried out a lot of years.In order to produce these hydrocarbons, production system can be for special duty utilizes various devices in well, as sand screen and other instrument.Usually, these devices are placed into as in the well bore of completing by cased hole completion or barefoot completion method.In the cased hole completion method, casing string is placed in well bore and bores a hole from the casing string to the subsurface formations provides the flow channel that enters well bore for formation fluid (as hydrocarbon).Alternatively, in the barefoot completion method, what put into well bore is flow string and there is no casing string.Formation fluids is by the annulus between subsurface formations and flow string (or annular space), thus the inflow flow string.

Yet when producing hydrocarbon from subsurface formations, because the position of some subsurface formations, operation becomes and has more challenge.For example, some subsurface formations are arranged in the interval with high sand content of super deep water, exceed drill-well operation can and depth, be in the high pressure/high temperature oil reservoirs in the long intervals of high yield and remote location.Such a situation, the position of subsurface formations may throw into question, and as sand control failure, this can significantly increase the cost of single oil well.That is to say, for economic oil field development, the cost that enters subsurface formations can cause still less well by completion.For example, the sand control unsuccessfully can cause the top layer to produce sand, and underground equipment damages, and reduces the loss of well production and/or oil well.Therefore, the reliability of well and life-span become design consideration to avoid undesirable production loss and to costliness intervention or the well-repairing work of these wells.

Sand control installation or sand control device (sand control device) are to increase well reliability and the exemplary device in life-span for well.Sand control device is arranged on the down-hole of passing the stratum usually to keep solid matter and to allow to produce without the formation fluid greater than the solid matter of certain size.Usually, sand control device is used in well to control the generation of solid matter such as sand.This sand control device can also can be surrounded by filter screen in the slotted perforate of tool.For example, when when being arranged in the subsurface formations grown place layer fluid of deep water, because excavated and formation fluid withdraws from the down-hole pressure that causes and causes the bad or stratum reduction of stratum consolidation by well bore, so may produce solid matter together with formation fluid.

Yet under rugged environment day by day, because high pressure, burn into stop up, compacting/reasons such as precipitation, sand control device is more prone to damaged.Therefore, generally utilize sand control device by other method, fill or fluid treatment as gravel, to control from stratum output sand.

A kind of the most frequently used method for control sand is that gravel is filled.Gravel is filled well and is included in the sand control device placed around gravel that is connected to flow string or other particulate matter to strengthen sand filtration and stratum integrality.For example, in the barefoot completion method, gravel is filled and is usually placed between wellbore wall and the sand screen around the perforation central tube.And in the cased hole completion method, gravel is filled and is usually placed between the casing string and the sand screen around the perforation central tube with perforation.No matter what the type of completion is, formation fluid flows into flow string by at least two filters from subsurface formations: gravel is filled and sand control device.

Fill by gravel, the loss meeting that is not intended to of carrying liquid forms sand bridge in the interval of being filled by gravel.For example, in or the pay interval that tilts thick at, the bad distribution of gravel (be the incomplete filling of interval cause gravel the space in filling) can occur, the liquid premature loss being accompanied by from gravel mud to the stratum.This fluid loss can cause forming sand bridge in annulus before the gravel filling is completed.For tackling this problem, can be used to walk around sand bridge and even distribution gravel in interval as the instead of flow passage of isocon.For the more details of this instead of flow passage, see to be numbered 5,515 915,5,868,200,5,890,533,6,059,032,6,588,506,4,945,991,5,082,052,5,113,935,5,333,688 United States Patent (USP) and publication number are the international application of WO2004/094784; These materials are incorporated herein by reference.

Utilize the instead of flow passage to be highly profitable, but cause the design challenge of making flow string, as packer being connected to sand control device or other well tool.Packer prevents by around the flowing of the well bore of instead of flow passage, but allows flowing and allowing under many circumstances flowing by primary flow channel in addition in the instead of flow passage.

Fill although isocon helps to form gravel, this use of isocon may limit to interlayer, and the method that provides gravel to fill is provided.For example, in the barefoot completion method, be impossible because form up and down complete gravel filling at packer, so packer is not mounted when utilizing gravel to fill.When not having gravel to fill, variety of issue can occur.For example, if interval in the stratum produces water, the decomposition of the material that this stratum just may keep together due to the drag force that increases and/or sand grains is caved in or was lost efficacy.Equally, because water is heavier and it is moved and transport the larger pressure of consumption from well than hydrocarbon, usually reduce output so produce water.That is to say, the water of output is more, and the pressure that can be used for transporting hydrocarbon (as oil) is less.In addition, if water be corrosive and process inappropriately, can cause serious device damage.At last, because water must suitably be disposed, so the output of water has increased processing, operation and cost of disposal.

This product water may also appear in such well, and described well has a plurality of different well completion intervals, and wherein formation strength changes to another interval from an interval.Because the estimation of formation strength is complicated, so beginning the ability of time of occurrence, prediction water is limited.Oil reservoirs are mixed to reduce investment risk and maximum economic benefit under many circumstances.The oil well that particularly has different intervals and marginal reserves may be mixed to reduce economic risk.One of risk in these configurations is: the gas in any one interval and/or water breakthrough threaten the remaining reserves in other interval of completion.Therefore, for the well that gravel is filled, the total system reliability of well completion has great uncertainty.

Therefore, for example need to be provided at the method and apparatus that the interlayer in the gravel filling is separated in the barefoot completion method.Equally, need to provide for sand control device well completion equipment and the method for instead of flow passage, the packer of described sand control device such as sand screen and the different intervals of the filling of gravel in well.

In Fig. 9 A-9B, sand control device 138a-138c and gravel are filled 140a-140c and are disposed in well bore 114 with packer 134a-134c, and described packer can be a kind of in packer discussed above. Sand control device 138a and 138b can comprise the interior isocon (not shown) that is arranged between central tube and sand screen, these sand control devices can be used to produce hydrocarbon from separately interval 108a and 108b, and the hydrocarbon of production can flow along flow channel 902 and 904.In Fig. 9 A, interval 108c is producing water along flow channel 904.Therefore, for separating this interval 108c, stopper 906 can be arranged on the position of packer 134c in central tube.This stopper 906 is separated the water yield formation section together with packer 134c and can be continued to produce other interval 108a and the 108b of hydrocarbon.Similarly, in Fig. 9 B, interval 108b is producing water.In order to separate interval 108b, straddle type external member 916 can be installed to separate water yield formation section 108b and to produce other interval 108a and the 108c of hydrocarbon along passage 912 between packer 134b and 134c.

In Fig. 9 C-9D, sand control device 138a-138c and gravel are filled 140a-140c and are disposed in in the bushing pipe 508 in the well bore 114 of packer 502a, b and 504a, b.Sand control device 138a and the 138b that can comprise interior isocon can be used for producing hydrocarbon from separately interval 108a and 108b, and the hydrocarbon of production can flow along flow channel 922.In Fig. 9 C, interval 108c is producing water along flow channel 924.Therefore, for separating this interval 108c, stopper 926 can be arranged on the position of the interior packer 502b of central tube and 504b.This stopper 926 is separated water yield formation section and other interval 108a and the 108b that can continue to produce hydrocarbon together with packer 502b and 504b.Similarly, in Fig. 9 D, interval 108b is producing water.Straddle type external member 928 can be installed to separate water yield formation section 108b and to produce other interval 108a and the 108c of hydrocarbon along passage 930 between packer 502a, b and 504a, b.

As the instantiation of isolation technique, can determine to produce the toe that water appears at the inclined shaft body.Measure to confirm to produce the water source and can determine this position by carrying out PLT.Then, can comprise that lock or the cotton rope of the slips profile shaft heart and balancing pole or coil pipe arrange plug and can be mounted to separate the water yield formation section.(cup-shaped packer for example is as MZ PACKER because packer ^TM(Schlumberger); Inflatable packer is as E-ZIP ^TM) in nipple profile (nippleprofile) (if comprising as the part of packer external member) be generally minimum in the completion post, so described stopper can be at non-selective mode operation.And it should be noted: if cotton rope is the work string type of selecting, tractor just can be used for surpassing the gradient of 65 degree.In case be set, cotton rope or coil pipe unit can be disassembled and resume production.

As another example, can determine that water is from the heel output of inclined shaft body.Equally, in this example, can confirm to produce the water source by carrying out the PLT measurement.Then, coil pipe can be assembled and the straddle type external member can be mounted to separate fully the water yield formation section.The straddle type external member can comprise the sealing stinger, stops locator (no-go locator), without coupling pipe and slips or lock shaft type hanger bracket.The straddle type external member can and be placed in wellhole to lay the stinger sealing of separating in packer near the coil pipe work string.Separate the water yield formation section and the hanger bracket whole external member of locking in position without coupling pipe.In case in place, the coil pipe unit is disassembled and resumes production.

In addition, by separate each interval with packer, provide and arranged gravel filling and the even different flexibility of gravel type in some intervals.For example, Figure 10 A-10B is the exemplary embodiment of filling according to the dissimilar gravel of the use of present technique many aspects, and wherein interlayer is separated provides by above-described packer.Therefore, can understand best these embodiment referring to Fig. 1,3A-3D, 4A-4D, 5A-5C and 9A-9D simultaneously.

In Figure 10 A-10B, sand control device 138a-138c is placed in well bore 114 with packer 134b and 134c.The sand control device 138a-138c that can comprise interior isocon can be used for producing hydrocarbon from interval 108a-108c separately.In Figure 10 A, the gravel that interval 108a and 108c are filled to form by interior isocon is filled 140a and 140c.Interior isocon in sand control device 138b can blocked and discord well bore 114 fluids connections.As a result, because the separation that provides due to packer 134b and 134c, gravel does not enter interval 108b, does not fill 140b so form gravel in interval 108b.Even separation is arranged, hydrocarbon is also via sand control device 138a-138c output from interval 108a-108c.In this example, due to the STOL content in this interval, so filling 140b, gravel do not form in interval 108b, and this can reduce well yield.Perhaps, due to the STOL intensity in interval 108b, gravel is filled not necessarily.Similarly, in Figure 10 B, gravel filling 140b and 140c veer away by direct split flow pump with interior isocon and put.The fluid of the interior isocon in the sand control device 138a that does not have and may be blocked is communicated with.Gravel is installed above packer 134b with traditional gravel filling technique is filled 140a.The size that gravel is filled 140a cobblestone can be different from the size of gravel filling 140b and 140c cobblestone to strengthen the well performance.In this situation, this interlayer is separated provides gravel to fill the flexibility of the gravel type of placing in layout and well.

In addition, it should be noted that present technique also can be used for injection and the processing of well.For example, in well injection period, isocon with can be similar to the effect that well is produced by flowing of packer, but provide flowing of different directions.Therefore, packer can be configured to functionally maybe can be designed to be used as to inject and producing well operates for Injection Well provides concrete.Therefore, Figure 11 A-11C is the dissimilar mobile exemplary embodiment of separating according to the interlayer that passes through to be provided by above-described packer of present technique many aspects.Therefore, can understand best these embodiment referring to Fig. 1,3A-3D, 4A-4D, 5A-5C and 9A-9D simultaneously.

In Figure 11 A, interior isocon 1101 is communicated with interval 108b fluid thinks that interval 108b provides the injection fluid.Injecting fluid can be water, gas or hydrocarbon, and its direction that indicates with arrow 1103 is injected into interval 108b.The injection of these fluids can be by directly shunting pumping execution.Because packer 134b and 134c provide the separation in well bore 114, so the fluid that injects does not enter interval 108a and 108c.When injection interval 108b, hydrocarbon is produced by the perforation of the central tube in sand control device 138a and 138c 1102 in the direction of arrow 1104.As noted above, because sand control device 138b can block with the straddle type external member, so the injection fluid that forms can remain on interval 108b.

In Figure 11 B, interior isocon 1110 is communicated with to provide the processing fluid in interval 108b with interval 108b fluid.Process fluid and can be used for making the well volume increase, its direction that indicates with arrow 1112 is injected into interval 108b.Equally, process fluid and can offer interval 108b by direct shunting pumping.Separation in the well bore 114 that provides due to packer 134b and 134c, the injection fluid that arrow 1112 indicates does not enter interval 108a and 108c.In this example, after processing operation, hydrocarbon is produced by the perforation of the central tube in sand control device 138a-138c 1102.Therefore, from the secondary flow channels of sand control device flow and the mobile of primary flow channel from sand control device mixes.

An example of this treatment technology is removing of filter cake.In this example, interval 108b comprises filter cake and sand control device 138a-138c is arranged in well bore 114.It can be machinery and/or chemical and can complete before or after gravel padding that filter cake removes processing.More specifically, filter cake is processed fluid and is directly pumped into secondary flow channels, and this passage is used for filter cake is processed the layer of sand face (sand face) that fluid imports to interval 108b, indicates as arrow 1112.Processing can be by blowback or not blowback.The preferred embodiment of this treatment technology uses combination with the replaceable channel technology of the isocon 1110 of spout (not shown), and described spout is attached to isocon and extends the length of sand control filter screen 138b.Can complete machinery towards surface of stratum with the stirring filter cake from the processing of spout by guide and remove, this can comprise that two-forty pumping or equipment can comprise spout or the mechanical agitator of particular design.Chemistry removes the use that can comprise acid, solvent or other compound.

In Figure 11 C, interior isocon 1120 is communicated with interval 108b fluid thinks that well provides the dual completion method.Production liquid by arrow 1122 indications produces into isocon by the opening as hole or groove.In this example, produce the passage that liquid indicates along arrow 1104, by the perforation 1102 on the central tube of sand control device 138a and 138c, from interval 108a and 108c output.Sand control device 138b can be blocked or make the central tube perforation to block to prevent the fluid mixing from interval 108a-108c by the straddle type external member.As a result, because packer 134b and 134c separate different interval 108a-108c, so can separate output with fluid in 108c by interior isocon 1120 with interval 108a from the produced fluid of interval 108b.Equally, can control separately secondary flow channels on ground.

As the alternate embodiment of packer 400, different geometrical configurations can be used for support component 418 to form division, interval and blocking-up, and they control the Fluid Flow in A in packer 100.As noted above, under present technique, support component 418 is used for forming the opening 420 between sleeve member and central tube.These support components 418 can be configured to provide redundancy flow channel or the blocking-up (interlocking) in packer 400.For example, support component 418 can be configured to form the opening of two openings, three openings, any number, until reach the number of sand control device 138 upper shunt tubes, or more than the opening of sand control device 138 upper shunt tubes.Like this, sand control device 138 and packer 400 can be produced hydrocarbon with isocon, maybe can provide various fluids or passage by well bore 114 with these different isocons.Therefore, support component 418 can be used to form the passage with various geometries.

In addition, it should be noted, the isocon that is used for above embodiment can be the outer or interior isocon with various geometries.Restriction, the pressure loss in space and the holding capacity of breaking or collapsing are depended in the selection of isocon shape.For example, isocon can be circle, rectangle, trapezoidal, polygon or other shape that is used for different application.The example of isocon comprises Exxon Mobil (ExxonMobil)
