Detailed description of the invention
What illustrate typically in Fig. 1 is system 10 for well and correlation technique.Well system 10 and method can adopt principle of the present disclosure, but it should be clearly understood that this system and method is only an example of the various system and methods that can construct in the scope of the present disclosure respectively and implement.
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 and flow into the completion tubular column 26 of tubulose substantially to allow fluid 22 from the stratum 24 penetrated by pit shaft, to allow product arrive ground.
In other example, the local pit shaft 14 flowing into pit shaft at fluid 22 can not be lined with sleeve pipe 16 and cement 18 (such as, pit shaft can be uncased or bore hole, such as, at packer less than 28, completion tubular column 26 seals and fixes in the wellbore by packer 28), pit shaft can be level or tilt, packer can comprise liner hanger, and completion tubular column, perforating gun (not shown) and tubing string 12 can be sent in pit shaft as each parts of single tubing string etc. in single trip.Therefore, should be appreciated that and can make many changes to the well system 10 described in Fig. 1 and method, still remain within the scope of the present disclosure simultaneously.
Tubing string 12 can be the type as work string known to those skilled in the art, and can be made up of pipeline section and/or continuous print oil pipe etc.The tubular material of any type may be used to tubing string, includes, but is not limited to the known tubing string as production tube, coiled tubing, composite oil pipe, wired tubing etc. of those skilled in the art.
The tubing string 12 of Fig. 1 has seal 30 on its lower end, in the closed hole 32 of packer 28 (or in the closed hole extension being connected to liner hanger etc.) seal.By this way, the flow channel 34 extending longitudinally through tubing string 12 is communicated with being configured to the inner sealing fluid of completion tubular column 26, and such as can flow through passage 34 at the test period on stratum 24 to make fluid 22.
Tubing string test macro 36 is interconnected in tubing string 12.In this example, test macro 36 allows when tubing string 12 is lowered to pit shaft 14 with well fluids filling column 12.
And test macro 36 allows the flow channel 34 be applied to by the pressure of increase above valve 38, to carry out pressure test in inside to tubing string 12.Tubing string 12 can by test pressure termly, and can restart to install when each pressure test success when being lowered to pit shaft 14.
Tubing string 12 also can have the testing valve 40 and circulating valve 42 that are interconnected in wherein, for formation testing 24 (such as, in pressure recover and pressure fall-off test), for setting up the circulation by tubing string after a test, etc.Suitable testing valve for using in tubing string 12 comprises by Halliburton Energy Serv Inc. of Houston, TX, USA (Halliburton Energy Services, Inc.) LPR-N (TM) sold and SELECT (TM) testing valve, and suitable circulating valve comprises the OMNI (TM) also sold by Halliburton Energy Serv Inc., RTTS (TM) and VIPR (TM) circulating valve.Certainly, without departing from the scope of the disclosure, testing valve and the circulating valve of other type can be used, and the use of testing valve and circulating valve is dispensable.
Valve 38 in test macro 36 stops the flowing by passage 34, makes during tubing string 12 pressure test, and the pressure being applied to the increase on valve can not spill the lower end of tubing string.But in order to allow tubing string 12 to be filled by well fluids when being lowered in pit shaft 14, bypass channel is arranged around valve 38.An example with the test macro 36 of such valve 38 and bypass channel 44 illustrates typically in Fig. 2 A-F.
The test macro 36 described 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 as test macro uses in the well system and method example of Fig. 1.But, it should be clearly understood that test macro 36 can use in other well system and method, remain 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 (see Fig. 2 B), makes the pressure increased can be applied to the portion section 34a of the flow channel 34 above valve.But, when 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 (see Fig. 2 B-D) and flow.
In the example described in Fig. 2 A-F, valve 38 comprises ball valve 48 and actuator 50.Actuator 50 comprises the piston 52 be reciprocally received in casing assembly 54.
Two air chambers 56,58 are separated, under these two air chambers are initially all in substantially the same pressure (such as, atmospheric pressure) by piston 52.Gas in room 56,58 can be air or inert gas, such as nitrogen etc.
The pressure isolation of room 58 with test macro 36 outside is initially opened by rupture disk 60.If test macro 36 uses in system 10, so this pressure is by the annular space 62 be radially formed between tubing string 12 and pit shaft 14.
Configuration (as depicted in Figure 3 B a) is opened in order to valve 38 is actuated to it from its closedown configuration (as depicted in fig. 2b), pressure in annular space 62 can be increased to predeterminated level, thus sheet 60 is broken and allows the pressure in annular space to enter room 58.This will be formed from room 58 to the pressure reduction of room 56, thus valve 38 is actuated to it opens configuration with upwards dislocation valve 38 (as shown in the figure) by offset piston 52.
Replace rupture disk 60, without departing from the scope of the disclosure, can use other device of interim isolation room 58 (such as, valve etc.) or releasedly fixed piston 52 to prevent other device (such as, shear pin etc.) of dislocation.In one example, one or more valve or other flow control apparatus can via telemetry (DYNALINK (TM) acoustic telemetry system such as, sold by Halliburton Energy Serv Inc.) such as from ground or the operated from a distances of neighbouring ground.
Preferably, until tubing string 12 is fully installed, or at least until there is not the demand of tubing string being carried out to pressure test, be just actuated to it from its closedown configuration opens configuration to valve 38.But without departing from the scope of the disclosure, valve 38 can activated at any time.
As depicted in fig. 2c, multiple flap valve 64 is connected in series in each extending longitudinally through in multiple bypass channels 44 of casing assembly 54.But, in other example, as required, single bypass channel 44 and single flap valve 64 can be used.
Flap valve 64 allows fluid 46 to flow to channel part section 34a from channel part section 34b, even if valve 38 stops and such flows through valve itself.Therefore, when tubing string is just mounted, can be in it closes configuration at valve 38 and uses fluid 46 filling column 12.
Multiple flap valve 64 is used to allow in flap valve one (or multiple) to lose efficacy, all the other flap valve simultaneously in flap valve can continue to stop fluid 46 to flow backward to channel part section 34b (such as, during the pressure test of tubing string 12) from channel part section 34a.Flap valve 64 may lose efficacy, such as, because chip stops the sealed engagement with the valve seat in flap valve.
In order to prevent chip from blocking bypass channel 44, or causing ball valve 48 or flap valve 64 fault etc., using strainer 66 to filter this fluid when fluid 46 enters bypass channel (see Fig. 2 D).Strainer 66 can be such as silk screen, sintering, material winds 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 riding bypass channel 44.
As shown in figure 2d, the upper end of mandrel 68 engages hermetically with seal 70, makes the fluid 46 flowing to bypass channel 44 from passage 34 have to flow through strainer 66.But, if mandrel 68 is by upwards dislocation, so strainer 66 also will upwards dislocation, and seal 70,72 is by the part (blank portion) of leaving a blank of engagement mandrels hermetically, thus anti-fluid 46 flow into bypass channel (as in Fig. 3 D describe).
Unacceptably blocked by chip when strainer 66 becomes, when making fluid 46 no longer can flow sufficiently through bypass channel 44, mandrel 68 upwards dislocation.Due to the restriction to the flowing through strainer, strainer 66 will form pressure reduction, and this pressure reduction can be used to dislocation strainer, as hereafter described 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 rooms 76,78 be separated by piston.Room 78 is exposed to the pressure in flow channel 34, and the pressure in room 76 is exposed between mandrel 68 and casing assembly annular region, and this annular region is also communicated with bypass channel 44 fluid in the downstream of strainer 66.
Certainly, bypass channel 44 is communicated with upper channel portion section 34a fluid, as discussed above.Therefore, room 76 and upper channel portion section 34a indirectly fluid are communicated with, and room 78 is communicated with lower passage portion section 34b fluid, and strainer 66 is sandwiched between channel part section 34a, 34b.
Such as, if the pressure in lower passage portion section 34b increases relative to the pressure in upper channel portion section 34a, if strainer 66 becomes when being blocked by chip, so piston 74 will be biased by pressure reduction with upwards dislocation, thus also upwards dislocation mandrel 68.When piston 74 distance that upwards dislocation is enough, both seals 70,72 all against the part sealing of leaving a blank of mandrel 68, thus prevent from flowing into bypass channel 44 (as in fig. 3d describe).
Therefore, when tubing string 12 is just being installed in pit shaft 14, strainer 66 is filtering the fluid 46 flowing to upper channel portion section 34a from lower passage portion section 34b.But, if strainer 66 becomes by chip blocking (no matter or unacceptably being limited for the flowing of what reason by strainer), so can be stoped expediently by the flowing of bypass channel 44.The pressure test of tubing string 12 still can be carried out, such as, by carrying out from ground filling column before each test.
As in figure 2d describe, bias unit 80 (such as, spring, compression air chamber etc.) can be used to downward dislocation mandrel 68 and strainer 66, if such as when the pressure reduction across filter 66 reduces, thus again allow fluid 46 flow through strainer and enter bypass channel 44.
Now other referring to Fig. 3 A-F, test macro 36 is shown in after strainer 66 and mandrel 68 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 by carrying out the formation testing using testing valve 40 subsequently, therefore now wishing that valve 38 is in and opening configuration.
It should be noted that in figure 3 a, rupture disk 60 breaks in response to the predetermined pressure being applied to annular space 62, thus on rupture disk, form corresponding pressure reduction.Piston 52 upwards dislocation, thus open valve 38, as shown in Figure 3 B.
In fig. 3d, can see, mandrel 68 upwards offsets, thus prevents the flowing entering bypass channel 44.In this example, bias unit 80 is not used.On the contrary, the holding device 82 in elastic locking collet 84 form is used to prevent mandrel 68 dislocation downwards after upwards dislocation.Therefore, in this example, once be stoped by the upwards dislocation of mandrel 68 by the flowing of bypass channel 44, such flowing just can not be allowed to again (do not fetch test macro 12 and reset).
The holding device 82 of other suitable type can comprise clasp, breech lock, lock dog etc.Once realize 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 stop by the flowing of bypass channel 44.To the emergency measure that the prevention of the flowing by bypass channel 44 is preferably taked in the unacceptably confined situation of the flowing of the fluid 46 by strainer 66.
Although valve 38 is depicted as in the accompanying drawings comprise ball valve 48, should be appreciated that if needs, the valve (such as, baffle-type valve, gate valve or telescoping valve etc.) of other type can be used.A beneficial aspects of ball valve 48 is, it is preventing scrap, reliably, and it preferably can be sealed by the flowing of flow channel 34 on arbitrary longitudinal direction.When using floating rig to be sent in pit shaft 14 by tubing string 12, a rear feature may be especially useful, because heave movement can not cause fluid 46 upwards to flow through ball valve 48.
Flap valve 64 can have bias unit 86 (such as, the form in pressure-relief valve, see Fig. 2 C and Fig. 3 C), thus when 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 depth difference of the correspondence of the fluid in passage 34 and annular space 62 produces this pressure reduction.
Such as, 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, thus opens flap valve and filling column 12.
If needed, flap valve 64 can be deactivated, thus allows fluid 46 to flow to channel part section 34b by bypass channel 44 from channel part section 34a.This may be required, such as, by when carrying out the pressure test of the tubing string 12 below valve 38 when not opening valve 38.
A kind of mode realizing this result will be construct casing assembly 54 by nonmagnetic substance, be at least that part around flap valve 64.Magnetic devices 88 (such as, permanent magnet, electromagnet, magnetostriction materials etc., see Fig. 3 B) can be then positioned in passage 34 (such as, by steel wire cable, coiled tubing transmit, from transmit etc.), and operated to produce the magnetic field being enough to flap valve 64 is pulled away from its valve seat, thus allow adverse current by bypass channel 44.
In another optional feature, valve (not shown) can be used to provide the selective circulation with room 56.In this example, pressure in room 58 can increase relative to the pressure in room 56 to open valve 38 (such as, to allow the tubing string 12 below valve 38 is carried out to pressure test, do not produce harmful pressure reduction to allow seal 30 to enter sealing endoporus 32 on seal, etc.), or the pressure in room 56 can increase with valve-off (such as relative to the pressure in room 58, to allow to carry out pressure test to the tubing string 12 above valve 38, etc.).
Can understand completely now, the field of the disclosure to structure tubing string test macro produces significant progressive.In an above-mentioned example, strainer 66 filters the fluid 46 flowing through bypass channel 44, thus prevents the fault of valve 38 and flap valve 64.To the unacceptable high-drag by the flowing of strainer 66 (such as, chip etc. due in strainer) situation in, bypass channel 44 can be closed, and by with from ground fluid filling tubing string and then facing to close valve 38 apply pressure, still can carry out pressure test to tubing string 12.
Below openly describe the tubing string test macro 36 for using together with the tubing string 12 with flow channel 34, flow channel 34 extends longitudinally through tubing string 12.In one example, test macro 36 can comprise: valve 38, and it optionally allows and stop to provide fluid to be communicated with at flow channel 34 between section 34a, 34b; Bypass channel 44, it provides fluid to be communicated with when valve 38 is closed at flow channel 34 between section 34a, 34b; And strainer 66, it filters the fluid 46 flowing through bypass channel 44.
The flowing by bypass channel 44 is stoped in response to forming predetermined pressure reduction on strainer 66.In one example, bias unit 80 can cause the flowing allowed by bypass channel 44 in response to the reduction of the pressure reduction on strainer 66.
Can in response to the restriction of the increase to the stream by strainer 66 and/or in response to the flowing forming predetermined pressure reduction to stop by bypass channel 44 on strainer 66.
Test macro 36 also can comprise at least one flap valve 64, and this flap valve allows along the flowing by bypass channel 44 on a direction, and stops in opposite direction by the flowing of bypass channel 44.This at least one flap valve 64 can comprise multiple flap valve 64 of series connection.Flap valve 64 can be interconnected in the bypass channel 44 in strainer 66 downstream.
Valve 38 can comprise ball valve 48.Valve 38 can stop between flow channel portion section 34a, 34b, on two longitudinal directions by the flowing of valve 38 when closing.
More than also describe a kind of method of test string 12.In one example, the method can comprise: allow fluid 46 to flow through bypass channel 44, bypass channel 44 connects the portion section 34a, the 34b that extend longitudinally through the flow channel 34 of tubing string 12, and strainer 66 filters the fluid 46 flowing through bypass channel 44; The valve 38 of tubing string test macro 36 stop fluid 46 flow channel 34 between portion section 34a, 34b by the flowing of valve 38; And stop the flowing by bypass channel 44 in response to forming predetermined pressure reduction on strainer 66.
While the method also can be included in valve-off 38, increase the pressure in a 34a of flow channel portion section, thus pressure test is carried out to tubing string 12.At least one flap valve 64 that pressure test can comprise tubing string test macro 36 stops from a flowing by bypass channel 44 flow channel portion section 34a.
Flap valve 64 can be positioned in the nonmagnetic portion of casing assembly 54.The method can comprise operation magnetic devices 88, thus causes flap valve 64 to allow to be flowed by flap valve 64 in two opposite directions.
