具体实施方式 Detailed ways

[0054] 图1示出了用于在井4的裸眼部分3中密封生产水61的生产区域30的井下密封系统100。 [0054] FIG 1 illustrates a sealing system for a downhole borehole 4 in the production of the water seal portion 61 of the production zone 330 of 100. 井下密封系统100包括第一和第二环形基础结构2和设置在两个环形基础结构之间的管子31,以使得管子的第一管子端53重叠于第一环形基础结构并且管子的第二管子端54重叠于第二环形基础结构。 The downhole system 100 includes a first seal and a second annular basic structure 2 and the tube 31 disposed between the two annular base structure, so that the first tube end 53 of the pipe overlaps the first and second annular tube infrastructure tube a second annular end 54 overlaps the base structure. 系统100还包括设置在环形基础结构2和管子31之间的两个封隔器32。 The system 100 further includes two packers 32 between the ring 31 and the tube 2 infrastructure. 环形基础结构2压在井的裸眼部分的壁3a上,并且因而与封隔器一起在管子31的外侧提供环形屏障,所述环形屏障密封生产区域30。 The annular structure 2 is pressed against the base wall portion 3a of the open-hole well, and thus provides the packer 31 together with the outer tube an annular barrier, the annular barrier seal 30 production areas. 每一环形基础结构2包括围绕可扩张管道10的环形密封元件11,可扩张管道10将环形密封元件压向井4的裸眼部分3的壁3a。 Each ring comprises a base structure 2 around an expandable annular sealing element 10 of the pipe 11, the duct 10 may be expandable annular seal member against the borehole wall 3a of the portion 3 of 4.

[0055] 环形基础结构通过井下安装工具1安装,如图2-10所示。 [0055] By mounting the annular downhole infrastructure installation tool 1, shown in Figure 2-10. 井下安装工具1包括具有工具轴线6的工具主体5和轴7,在轴的第二端9轴连接至工具主体。 1 comprises a downhole tool having a tool mounting axis of the tool body 56 and the shaft 7 is connected to the tool body at the second end 9 of the shaft. 轴7的第一端8通过位于输送位的可扩张管道10从工具壳体29中伸出,在输送位可扩张管道具有未扩张的直径du。 The shaft 7 extends from a first end 810 of the tool housing 29 by the conveying position expandable conduit, having a diameter du unexpanded expandable conduit in the conveying position. 在图1中,可扩张管道10具有扩张位,在扩张位扩张管道具有扩张的直径4。 In Figure 1, the expandable conduit 10 having an expanded position, having expanded diameter in the expanded 4-bit expansion pipe. 如图2-10所示,轴7还通过环形密封元件11延伸并且进入设置在轴7的第一端用于扩张管道10和环形密封元件11的管道扩张元件12。 Shown in Figure 2-10, shaft 7 extends through an annular seal member 11 and into an expansion chamber 10 disposed in the pipe 11 and the annular sealing member 12 of the expansion element 7 of the first end of a shaft. 因而,可扩张管道10和环形密封元件11沿着工具轴线6相继布置,因此最小化了安装工具1的外径。 Thus, the expandable conduit 10 annular sealing member 116 and arranged in succession along the tool axis, thus minimizing the outer diameter of the tool 1 is installed. 安装工具1因此能够向下穿过井的带套管部分(未示出)至井4的裸眼部分3。 An installation tool with the sleeve portion can thus down through the well (not shown) to the open hole section of the well 4 3.

[0056] 如图2所示,井下安装工具1还包括具有倾斜外表面15的第二扩张元件14,环形密封元件11在倾斜外表面15上滑动,如图3所示,以给环形密封元件提供大于可扩张管道10的未扩张外直径du的内直径di。 [0056] 2, further comprising a downhole tool mounting having a second expansion member 14 is inclined outer surface 15, an annular seal member 11 on the inclined outer surface of the slide 15, shown in Figure 3, to send annular sealing element provide more than the inner diameter of the expandable conduit 10 di unexpanded outer diameter of the du. 环形密封元件11具有面向扩张元件14的外表面15的倾斜表面34,并且在轴7缩回至工具主体5中时,具有更宽部分27的轴的第一端8压在环形密封元件11上并且因而推压环形密封元件以在第二扩张元件14的倾斜表面34上滑动。 Annular sealing element 11 facing the expanding member has an outer surface 14 of the inclined surface 15 34, and is retracted to the tool body 75 when the shaft, the shaft having a first end 8 of the wider portion 27 is pressed against the annular sealing element 11 on and thus pushed to slide on the inclined surface 34 of the second expansion member 14 is pressed annular sealing element. 第二扩张元件14为空心,环绕轴7延伸,放置为部分在可扩张管道10内并且通过例如剪切销的可断裂部件35紧固至可扩张管道。 The second expansion member 14 is a hollow, extends around the shaft 7, placed in a portion of the expandable conduit 10 and the shear pins, for example, by rupturable member 35 secured to the expandable conduit. 通过这种方式,环形密封元件11被推入至可扩张管道10的外侧36,如图3所示。 In this manner, an annular sealing member 11 is pushed into the expandable conduit 10 to the outside 36, as shown in FIG. 可扩张管道元件12因而是推压元件。 The expandable conduit 12 is thus urging member member.

[0057] 为了收回轴7,井下安装工具1还包括液压缸19,如图2所示。 [0057] In order to recover the shaft 7, the downhole tool 1 further comprises mounting a hydraulic cylinder 19, as shown in FIG. 液压缸19包括缸壳体24和活塞23,形成轴7的第二端9的一部分。 The hydraulic cylinder 19 includes a cylinder housing 24 and piston 23, forms part of a second end of the shaft 9 7. 活塞23将缸壳体24分成第一壳体部分37和第二壳体部分38,并且当加压流体注入至第一壳体部分时,轴7上的活塞移动,轴缩回至工具主体5中。 The piston 23 of the cylinder housing 24 into a first housing portion 37 and the second housing portion 38, and when a pressurized fluid is injected into the first housing portion, the movement of the piston shaft 7, the shaft 5 is retracted to the tool body in.

[0058] 当环形密封元件11已经一路被推压至可扩张管道10上时,轴7进一步被缩回至工具主体5中,如图4所示。 [0058] When the annular sealing member 11 has been pushed all the way to the expandable conduit 10, shaft 7 is retracted further to the tool body 5 as shown in Fig. 管道扩张元件12包括可在半径方向移动的数个锥形区段20, 并且在这个阶段,锥形区段20已经径向向外移动,并且因而爬过更宽部分27上的阶梯式半径增加的表面28。 Expandable conduit 12 includes a movable element in the radial direction a plurality of conical section 20, and at this stage, the tapered section 20 has moved radially outwardly and thus increasing the climb over the stepped portion 27 is wider radius surface 28. 通过这种方式,轴7的第一端8的外直径增加,并且当轴被进一步缩回时,可扩张管道10和环形密封元件11被扩张。 In this manner, the outer diameter of the shaft 8 of the first end 7 increases, and when the shaft is further retracted, the expandable conduit 10 and the annular sealing member 11 is expanded. 当轴7的第一端8的更宽部分27向工具主体5运动时,第二扩张元件14的可断裂部件断裂,第二扩张元件被允许移动至可扩张管道10内。 When the motion to the tool body 275 a first end of the wider portion 7 of the shaft 8, a second expandable member rupturable member 14 is broken, the second expandable member is allowed to move within the expandable conduit 10.

[0059] 随着管道扩张元件12向着工具主体5进一步移动,可扩张管道10完全扩张,如图5所示,第二扩张元件也被推压至工具壳体29中。 [0059] With the expansion of the pipe member 12 is moved further toward the tool body 5, the expandable conduit 10 is fully expanded, as shown in FIG. 5, the second expandable member is also pushed to the tool housing 29. 为了能够完全扩张可扩张管道10,井下安装工具1还包括在工具主体5和可扩张管道10之间围绕轴7布置的割缝衬管25的形式的可扩张管子。 In order to fully expand the expandable conduit 10, further comprising a downhole installation tool between the tool body 5 and the expansion chamber 10 may be disposed about the shaft 7 slotted liner 25 in the form of expandable tubes. 当管道扩张元件12进一步向工具主体5移动时,割缝衬管25通过管道扩张元件12扩张,因而使得管道扩张元件12能够在割缝衬管25内穿过。 When expanding the pipe member is moved further toward the tool body 512, the slotted liner 25 the expansion member 12 through line expansion, thus making the dilatation element 12 to pass through conduit 25 in the slotted liner. 通过这种方式,工具能够完全扩张可扩张管道10和环形密封元件11以压靠在井的裸眼部分3的壁上,如图1 示出,即使井的裸眼部分具有大于井的带套管部分的直径,因为环形密封元件11在可扩张管道10的外侧被挤压,管道10保持环形密封元件11压向井的裸眼部分3的壁。 In this way, the tool can be fully expand the expandable conduit 10 and the annular sealing member 11 is pressed against the wall of the well open hole section 3, shown in FIG. 1, even if the open-hole portion of the well having a cased portion of the well is greater than diameter, annular sealing element 11 as is compressed on the outside of the expandable conduit 10, the conduit 10 holding annular sealing element 11 against the borehole wall portion 3.
