Detailed description of the invention
What in Fig. 1, illustrate typically is system 10 and the correlation technique for well.Well system 10 and method can adopt principle of the present disclosure, but it should be clearly understood that this system and method be only can be respectively in the scope of the present disclosure an example of structure and the various system and methods implemented.
In the example of Fig. 1, tubing string 12 is sent on pit shaft 14.Pit shaft 14 can be lined with sleeve pipe 16 and cement 18, and has perforation 20 to allow fluid 22 to flow into the completion tubular column 26 of tubulose substantially from the stratum 24 being penetrated by pit shaft, to allow product arrive ground.
In other example, the local pit shaft 14 that flows into pit shaft at fluid 22 (for example can not be lined with sleeve pipe 16 and cement 18, pit shaft can be uncased or bore hole, for example, at packer below 28, packer 28 seals completion tubular column 26 and be fixed in pit shaft), pit shaft can be level or tilt, packer can comprise liner hanger, completion tubular column, perforating gun (not shown) and tubing string 12 can be in single trip as each parts of single tubing string etc. and be sent in pit shaft.Therefore, should be appreciated that and can make many changes to the well system 10 of describing in Fig. 1 and method, still remain within the scope of the present disclosure simultaneously.
The tubing string 12 of Fig. 1 has the seal 30 on its lower end, in the closed hole 32 of packer 28 (or at the closed hole extension that is connected to liner hanger etc.) seal.By this way, longitudinal extension is communicated with the inner sealing fluid of completion tubular column 26 being configured to through the flow channel 34 of tubing string 12, to make fluid 22 for example to flow through passage 34 at the test period on stratum 24.
Tubing string test macro 36 is interconnected in tubing string 12.In this example, test macro 36 allows in the time that tubing string 12 is lowered to pit shaft 14 with well fluids filling column 12.
And test macro 36 allows the pressure of increase to be applied to the flow channel 34 of valve 38 tops, to tubing string 12 is carried out to pressure test in inside.Tubing string 12 can be by test pressure termly in the time being lowered to pit shaft 14, and can restart to install in the time of each pressure test success.
The test macro 36 of describing in Fig. 2 A-F can use in the well system 10 of Fig. 1 and method, and test macro further describes in this article and in the well system and method example of Fig. 1, uses for test macro.But, it should be clearly understood that test macro 36 can use in other well system and method, remains within the scope of the present disclosure simultaneously.
Although tubing string 12 is installed in pit shaft 14, the valve 38 of test macro 36 is closed (referring to Fig. 2 B), makes the pressure increasing can be applied to the section 34a of portion of the flow channel 34 of valve top.But, in the time that tubing string 12 is just being lowered to pit shaft 14, even if valve is closed, allows well fluids 46 to walk around valve 38 by bypass channel 44 (referring to Fig. 2 B-D) and flow.
In the example of describing in Fig. 2 A-F, valve 38 comprises ball valve 48 and actuator 50.Actuator 50 comprises the piston 52 being reciprocally received in casing assembly 54.
Piston 52 separates two air chambers 56,58, and these two air chambers are initially all for example, under substantially the same pressure (, atmospheric pressure).Gas in chamber 56,58 can be air or inert gas, such as nitrogen etc.
Be actuated to it and open configuration (as depicted in Figure 3 B a) for valve 38 is closed to configuration (as described Fig. 2 B) from it, pressure in annular space 62 can be increased to predeterminated level, thereby sheet 60 is broken and allow the pressure in annular space to enter chamber 58.This will form from the pressure reduction of 58Dao chamber, chamber 56, thereby offset piston 52 is with dislocation valve 38 (as shown in the figure) upwards and valve 38 is actuated to it opens configuration.
Replace rupture disk 60, without departing from the scope of the disclosure, can use other device (for example, valve etc.) of interim isolation room 58 or releasedly fixed piston 52 for example, to prevent other device (, shear pin etc.) of dislocation.In one example, one or more valves or other flow control apparatus can for example, via telemetry (DYNALINK (TM) acoustic telemetry system of, being sold by Halliburton Energy Serv Inc.) for example, from ground or near the operated from a distance of ground.
Preferably, until tubing string 12 fully installed, or at least until there is not the demand of tubing string being carried out to pressure test, valve 38 is just closed configuration and is actuated to it and opens configuration from it.But without departing from the scope of the disclosure, valve 38 can activated at any time.
As described in Fig. 2 C, multiple flap valve 64 are connected in series in longitudinal extension and pass in each in multiple bypass channels 44 of casing assembly 54.But, in other example, as required, can use single bypass channel 44 and single flap valve 64.
Flap valve 64 allows fluid 46 to flow to channel part section 34a from channel part section 34b, even if valve 38 stops such stream by valve itself.Therefore,, in the time that tubing string is just mounted, can in the situation that closing configuration, it use at valve 38 fluid 46 filling columns 12.
Use multiple flap valve 64 to allow one (or multiple) in flap valve to lose efficacy, all the other flap valve in flap valve can continue to stop fluid 46 to flow backward to channel part section 34b (for example,, during the pressure test of tubing string 12) from channel part section 34a simultaneously.Flap valve 64 may lose efficacy, for example, and due to the sealed engagement of the valve seat in chip prevention and flap valve.
In order to prevent that chip from stopping up bypass channel 44, or cause ball valve 48 or flap valve 64 faults etc., in the time that fluid 46 enters bypass channel (referring to Fig. 2 D), filter this fluid with strainer 66.Strainer 66 can be for example silk screen, sintering, that wire rod is wound around or the strainer of other type.It should be noted that in this example, strainer 66 is merged in the longitudinal part section of mandrel 68, and the external surface of mandrel 68 can be engaged hermetically by the seal 70,72 that rides bypass channel 44.
As shown at Fig. 2 D, the upper end of mandrel 68 engages hermetically with seal 70, makes the fluid 46 that flow to bypass channel 44 from passage 34 must flow through strainer 66.But, if mandrel 68 is by dislocation upwards, so strainer 66 also will be upwards dislocation, and seal 70,72 is the part (blank portion) of leaving a blank of engage mandrels hermetically, thereby prevents that fluid 46 from flowing into bypass channel (as described in Fig. 3 D).
When becoming by chip, unacceptably stops up by strainer 66, while making fluid 46 no longer can flow through bypass channel 44 fully, and upwards dislocation of mandrel 68.Due to through the mobile restriction of strainer, on strainer 66, will form pressure reduction, and this pressure reduction can be used to dislocation strainer, as below description more fully.
In Fig. 2 E, can see, piston 74 is connected to mandrel 68, and is reciprocally received in casing assembly 54.Piston 74 is exposed to the pressure in two chambers 76,78 that separated by piston.Chamber 78 is exposed to the pressure in flow channel 34, and chamber 76 is exposed to the pressure in the annular region between mandrel 68 and casing assembly, and this annular region is also communicated with in the downstream of strainer 66 and with bypass channel 44 fluids.
Certainly, bypass channel 44 is communicated with upper channel portion section 34a fluid, as discussed above.Therefore, chamber 76 and the section 34a of upper channel portion indirectly fluid are communicated with, and chamber 78 is communicated with lower passage portion section 34b fluid, and 66 of strainers are sandwiched between channel part section 34a, 34b.
If the pressure in the section 34b of lower passage portion increases with respect to pressure in the section 34a of upper channel portion, for example, if strainer 66 becomes while obstruction by chip, piston 74 will be setovered with dislocation upwards by pressure reduction so, thus also dislocation mandrel 68 upwards.When piston 74 is upwards when the enough distance of dislocation, seal 70,72 both all against the part sealing of leaving a blank of mandrel 68, thereby prevent from flowing into bypass channel 44 (as described) in Fig. 3 D.
Therefore,, in the time that tubing string 12 is just being installed in pit shaft 14, strainer 66 filters the fluid 46 that flow to the section 34a of upper channel portion from the section 34b of lower passage portion.But, if becoming by chip, strainer 66 stops up (no matter or for what reason unacceptably being limited by flowing of strainer), can be stoped expediently by flowing of bypass channel 44 so.The pressure test of tubing string 12 still can be carried out, for example, by carrying out from ground filling column before each test.
As described in Fig. 2 D, bias unit 80 (for example, spring, compression air chamber etc.) can be used to downward dislocation mandrel 68 and strainer 66, if for example in the time reducing across the pressure reduction of strainer 66, thereby again allow fluid 46 to flow through strainer and enter bypass channel 44.
Now in addition referring to Fig. 3 A-F, test macro 36 is shown in after strainer 66 and mandrel 68 be upwards offset to close bypass channel 44 typically, and after actuator 50 is operated to open valve 38.In this example, tubing string 12 is arranged in pit shaft 14 fully, and will carry out subsequently the formation testing of use test valve 40, therefore now wishes that valve 38 is in opening configuration.
It should be noted that, in Fig. 3 A, rupture disk 60 breaks in response to being applied to the predetermined pressure of annular space 62, thereby on rupture disk, forms corresponding pressure reduction.Upwards dislocation of piston 52, thus valve 38 opened, as shown in Figure 3 B.
In Fig. 3 D, can see, mandrel 68 is upwards offset, thereby prevents from entering flowing of bypass channel 44.In this example, do not use bias unit 80.On the contrary, the holding device 82 that is elastic locking collet 84 forms is used to prevent mandrel 68 dislocation downwards after dislocation upwards.Therefore, in this example, once be stoped by the upwards dislocation of mandrel 68 by flowing of bypass channel 44, such flowing just can not be allowed to (do not fetch test macro 12 and reset) again.
The holding device 82 of other adequate types can comprise clasp, breech lock, lock dog etc.Once realized certain dislocation, holding device 82 just can fixed central spindle 68 to prevent further dislocation.
It should be noted that in the process of operational testing system 36, unnecessary upwards dislocation mandrel 68 or prevention are flowed by bypass channel 44.The emergency measure that mobile prevention by bypass channel 44 is preferably taked in the unacceptably confined situation that flows of the fluid 46 by strainer 66.
Flap valve 64 can have bias unit 86 (for example, being the form of pressure-relief valve, referring to Fig. 2 C and Fig. 3 C), thereby in the time forming predetermined pressure difference from channel part section 34b to channel part section 34a, flap valve is opened.This pressure reduction can be selected, and makes the fluid 46 for certain density, and certain corresponding depth difference of the fluid in passage 34 and annular space 62 produces this pressure reduction.
For example, bias unit 86 can be set up, and makes, along with tubing string 12 is lowered in pit shaft 14, to keep the consistent depth difference of fluid 46 between passage 34 and annular space 62.By this way, before carrying out pressure test, passage 34 will only need to be filled this depth difference.Alternatively, before carrying out pressure test, pressure can be applied to annular space 62 as required to form predetermined pressure reduction on flap valve 64, thereby opens flap valve filling column 12.
If needed, flap valve 64 can be deactivated, thereby allows fluid 46 to flow to channel part section 34b by bypass channel 44 from channel part section 34a.This may be required, for example, by carry out the pressure test of the tubing string 12 below valve 38 in the situation that not opening valve 38 time.
A kind of mode that realizes this result will be by nonmagnetic substance structure casing assembly 54, be at least that part around flap valve 64.Magnetic devices 88 (for example, permanent magnet, electromagnet, magnetostriction materials etc., referring to Fig. 3 B) (for example can then be positioned in passage 34, transmitted by steel wire cable, coiled tubing, certainly transmit etc.), and operated to produce the magnetic field that is enough to flap valve 64 to be pulled away from its valve seat, thereby allow adverse current by bypass channel 44.
In another optional feature, valve (not shown) can be used to provide the selective circulation with chamber 56.In this example, pressure in chamber 58 can (for example increase to open valve 38 with respect to the pressure in chamber 56, with permission, the tubing string 12 of valve 38 belows is carried out pressure test, on seal, do not produce harmful pressure reduction to allow seal 30 to enter sealing endoporus 32, etc.), or the pressure in chamber 56 can with valve-off (for example increase with respect to the pressure in chamber 58, to allow that the tubing string 12 of valve 38 tops is carried out to pressure test, etc.).
Can understand completely now, the disclosure produces significant progressive to the field of structure tubing string test macro.In an above-mentioned example, strainer 66 filters and flows through the fluid 46 of bypass channel 44, thereby prevents the fault of valve 38 and flap valve 64.In the unacceptable high-drag of flowing to by strainer 66 (for example, due to chip in strainer etc.) situation in, bypass channel 44 can be closed, and by using from the fluid filling tubing string on ground and then exerting pressure facing to the valve 38 of closing, still can carry out pressure test to tubing string 12.
Below openly described the tubing string test macro 36 using for together with having the tubing string 12 of flow channel 34, flow channel 34 longitudinal extensions are through tubing string 12.In one example, test macro 36 can comprise: valve 38, and it optionally allows and stops between the section 34a of portion, the 34b of flow channel 34, to provide fluid to be communicated with; Bypass channel 44, it provides fluid to be communicated with in the time that valve 38 is closed between the section 34a of portion, the 34b of flow channel 34; And strainer 66, the fluid 46 of bypass channel 44 is flow through in its filtration.
Stop flowing by bypass channel 44 in response to form predetermined pressure reduction on strainer 66.In one example, bias unit 80 can cause in response to the reducing of pressure reduction on strainer 66 and allow flowing by bypass channel 44.
Can stop flowing by bypass channel 44 in response to the restriction of the increase of the stream to by strainer 66 and/or in response to form predetermined pressure reduction on strainer 66.
A kind of method of test string 12 has below also been described.In one example, the method can comprise: allow fluid 46 to flow through bypass channel 44, bypass channel 44 connects portion section 34a, the 34b of longitudinal extension through the flow channel 34 of tubing string 12, and strainer 66 filters the fluid 46 that flows through bypass channel 44; The valve 38 of tubing string test macro 36 stops fluid 46 flowing by valve 38 between the section 34a of portion, the 34b of flow channel 34; And stop in response to form predetermined pressure reduction on strainer 66 by bypass channel 44 flow.
When the method also can be included in valve-off 38, increase the pressure in a 34a of flow channel portion section, thereby tubing string 12 is carried out to pressure test.Pressure test can comprise that at least one flap valve 64 of tubing string test macro 36 stops flowing by bypass channel 44 from the section 34a of flow channel portion.
Flap valve 64 can be positioned in the nonmagnetic portion of casing assembly 54.The method can comprise operation magnetic devices 88, thereby causes flap valve 64 to allow to flow by flap valve 64 on two rightabouts.
