Description

用于向井下输送缆线的系统和方法 Delivery systems and methods for downhole cable

技术领域 FIELD

[0001] 本发明一般地涉及地下沉淀物的回收,更具体地,涉及用于从井中移除所产生的流体的方法和系统。 [0001] The present invention relates to subterranean recovered precipitate generally, and more particularly, to a method and system for removing the generated from fluid in the well.

背景技术 Background technique

[0002] 水平煤层气井特别容易受到在井筒中存在和聚集的固体颗粒所引起的生产问题的影响。 [0002] CBM horizontal wells are particularly susceptible to aggregation and production problems caused by solid particles in the wellbore. 例如,在水平煤层气井的寿命期间,能够随着瓦斯和水一同产生许多吨的小煤颗粒(术语为细煤粉)。 For example, during the lifetime of horizontal CBM well can produce many tons of small coal particles (pulverized coal terminology) together with the gas and water. 在井的早期阶段,这些固体颗粒通常对生产过程不会形成多少问题。 In the early stages of the well, the solid particles are usually not much problem in the production process is formed. 高流率的水和气体在井筒内产生足够大的速度使得固体颗粒保持夹带在生产流体中并且朝向安装在井里的泵送设备移动。 Water and high gas flow rates generated within the wellbore sufficient speed so that the solid particles remain entrained in the produced fluid and moves toward the pumping device mounted in the well. 在泵的入口,固体颗粒再次保持夹带在液相中并且被从井中抽出。 Pump inlet, and the entrained solid particles are held again in the liquid phase withdrawn from the well.

[0003] 在煤层气井寿命的后期阶段,细煤粉可能就开始对生产造成问题了。 [0003] In the later stages of the life of coal-bed methane wells, coal fines may cause problems to begin production. 仅仅气体流是不可能沿着井筒带走固体颗粒的,这将导致那些滞留的固体颗粒沉淀在井筒的小角度波状起伏里。 Only gas flows away along the wellbore is not possible solid particles, which would result in that the solid particles precipitated retained in the wellbore in a small angle of undulations. 这些固体颗粒最终会形成气流流动的限制,并且会导致产量下降。 These solid particles will eventually form a restriction in the air flow, and can lead to decreased yields. 此外,那些沉淀在泵的入口附近的固体颗粒可能阻塞泵的入口,因而降低泵从井筒中排除水的能力。 Further, those solid particles precipitated in the vicinity of the pump inlet may block the inlet of the pump, thereby reducing pump capacity to exclude water from the wellbore.

[0004] 井孔稳定性问题也能够对井的生产问题产生影响。 [0004] The wellbore stability problems can also have an impact on the well production problems. 在某些情况下,井筒可能倒塌并且会在井筒中沉淀大块,中块和小片的煤。 In some cases, the well bore may collapse and the bulk precipitate in the wellbore, and block coal platelets. 立方形的煤粒能够很容易地在井筒内形成桥进而限制井筒内流体的流动。 Cuboidal coal particles can be easily formed a bridge within the wellbore thereby limiting fluid flow within the wellbore. 这种限制能够进一步引起夹带固体颗粒的沉淀。 This limitation can be further cause precipitation of solid particles entrained.

[0005] 参考图1所示,井100包括井筒105,井筒105具有大致垂直部分110和大致水平部分115。 [0005] Referring to FIG. 1, a well 100 includes a wellbore 105, bore 105 having a generally vertical portion 110 and a substantially horizontal portion 115. 井筒105从地表面120延伸到位于地表面120下面的地层123。 Shaft 105 extends from the ground surface 120-120 formations below ground surface 123 is positioned. 泵125位于井下的大致水平部分115内并且通过传输缆线126电连接到位于地表面120的供电电源128。 Downhole pump 125 is located within a substantially horizontal portion 115 and is connected to a power supply 120 located on the ground surface 128 through the electrical transmission cable 126. 泵125设置成移除由地层123产生的液体127(例如水)。 Pump 125 is arranged to remove liquid from the formation 123 generates 127 (e.g. water). 液体通过管线(tubing string) 130 被抽吸到地表面120的贮水器133。 Liquid through line (tubing string) 130 is drawn into the surface 133 of the reservoir 120. 为了说明前面提到过的例子,井100可以是钻入煤地层的煤层气井。 To illustrate the example mentioned earlier, the well 100 may be drilled into the coal formation of coalbed methane wells. 固体颗粒(例如煤)的沉淀物135可能聚集在井筒内并且能阻塞泵125的入 Solid particles (e.g., coal) precipitate may accumulate within the wellbore 135 and can clog the pump 125

[0006] 一种已经用来克服固体颗粒在井中沉淀问题的方法包括在井的某点处注入附加流体,水或气体,由此增加流体流动速度。 [0006] A method has been used to overcome the problem of precipitation of solid particles in a well comprises injecting additional fluid, water or gas well at some point, thereby increasing the fluid flow velocity. 然而,流体流动速度的增加会以附加压力的形式恶化生产地层。 However, fluid flow velocity is increased to worsen the producing formation in the form of additional pressure. 还有,生产设备必须处理附加体积的注入的流体。 Further, the production equipment must handle the additional volume of the injected fluid. 另一种用来清除井筒的系统是使用搅动装置在井孔里纵向移动。 Another system for removing a wellbore using an agitation means is moved longitudinally in the well bore. 这个系统在搅动作用方面是有效的,但是,突然增大的固体颗粒可能会引起设备卡住并且使得整套机械设备不可使用。 This system is effective in terms of agitation, however, a sudden increase of the solid particles may cause jamming and the device such that entire machinery can not be used. 这两个系统所具有的低效和问题都被这里所描述的具体实施方式的系统和方法解决了。 This system has two problems and inefficiencies are a system and method for the specific embodiments described herein solves.

[0007] 从井中移除聚集的固体颗粒的水出现了与井下的泵的使用有关的其他问题。 [0007] water from the well to remove accumulated solids particles there are other problems with the use of downhole pump related. 由于必须要处理给泵的马达提供电力的泵的缆线使得泵的安装和移除变得复杂。 Since it is necessary to deal with the pump motor to the pump is provided such that the electric power cable installation and removal of the pump becomes complicated. 在泵的安装期间,输电缆线首先接(splice)在马达的导线上。 During installation of the pump, first transmission cable connection (splice) on the wire of the motor. 然后当泵下放到井中时将缆线附接到排出管。 Then down into the well when the cable is attached to the lower pump discharge pipe. 可以使用多种方法将缆线附接到管件上,包括夹具,粘合剂和特制的附接装置。 Various methods may be used to attach the cable to the tubular member, it includes a clamp, an adhesive, and a special attachment means.

[0008] 当泵安装到井中时,泵的缆线受到由于地表面磨损和破碎而易于毁坏的风险。 [0008] When the pump is mounted into the well, the pump of the cable are subject to risks due to surface abrasion and crushing easily destroyed. 当泵迅速经过井的偏斜部分时,风险显著增大。 When the pump rapidly through the deviated portion of the well, the risk of a significant increase. 经常使用扁平的钢包缆线来减小这些风险;然而,这种特殊的缆线价格昂贵并且只提供降低风险的增加等级。 Often using a flat cable ladle to reduce these risks; however, this particular cable expensive and only available to reduce the risk of increasing the level.

[0036] 井筒204可以包括大致竖直部分2M和大致水平部分258。 [0036] The wellbore 204 may include a generally vertical portion and a substantially horizontal portion 258 2M. 第一管线216的偏移部分2¾和第二管线MO的偏移部分244优选地大致定位在井筒204的大致水平部分258 内。 Offset portion of the first line 216 and preferably the second line 2¾ MO offset portion 244 is positioned substantially within a substantially horizontal portion 204 of the wellbore 258. 利用定位于地表面220的旋转器270旋转这些偏移部分224,244允许偏移部分224, 244 “擦拭”井筒204的圆周并且搅动已经沉淀在井筒204的大致水平部分258中的固体颗粒。 Rotator 220 to the ground surface by the positioning of the offset portions 224, 244, 270 to allow rotation of the offset portion 224, 244 "wiping" and the circumference of the wellbore 204 has been precipitated in agitated substantially horizontal section of the wellbore 204 258 solid particles. 该固体颗粒的搅动有助于保持固体颗粒夹带在井筒内的任何聚集的液体内,防止固体颗粒阻塞泵212的入口274。 The agitation helps to keep the solid particles entrained solid particles in a wellbore any accumulated liquid, prevent solid particles from clogging the inlet 274 of pump 212. 在一个具体实施方式中,第一管线和第二管线216,240的旋转可以连续地阻止固体颗粒在井筒204内沉淀,而在另一个具体实施方式中,第一管线和第二管线216,240仅仅间歇地操作使得允许固体颗粒在泵212的两次操作之间沉淀在井筒204内。 In a specific embodiment, the first pipeline and the second pipeline rotating continuously 216,240 may prevent precipitation of the solid particles within the wellbore 204, while in another embodiment, the first line and the second line 216,240 only intermittently operated so as to allow the solid particles between the operations of the pump 212 within the wellbore 204 precipitated. 虽然已经参照井筒204的大致水平部分258描述了擦拭操作,应当认识到的是, 第一管线和第二管线216和204的偏移部分224,244可以在井筒204的其他部分定位和操作,包括但不限于大致竖直部分244或沿着井筒204的曲线观0。 Although reference to a substantially horizontal wellbore section 204 258 describes the wiping operation, it should be appreciated that the first line and the second line 216 and the offset portion 204 of the other portions 224, 244 may be positioned in the wellbore 204 and operation, including but not limited to a substantially vertical or curved portion 244 Views 204 0 along the wellbore. 类似地,第一和第二管线216,204的偏移部分224,244可能沿着井筒204的带有套管的或者无套管的长度定位和操作。 Similarly, the offset portion of the first and second lines 216,204 and 224, 244 may operate with the sleeve along the length of the positioning or uncased wellbore 204.

[0037] 在一个具体实施方式中,第一和第二管线216,240的偏移部分224,244可以用螺旋型螺旋体预先形成。 [0037] In one embodiment, the offset portions 216,240 of the first and second lines 224, 244 may be formed in advance with a helical spiral. 螺旋型螺旋体的外扫掠直径可以是任何尺寸,达到和包括井筒直径。 An outer spiral of the spiral body swept diameter may be any size, up to and including wellbore diameter. 在一个具体实施中,第一和第二管线216,240的偏移部分224,244可以放置在泵212附近或与泵212邻接。 In one particular embodiment, the offset portions 216,240 of the first and second lines 224, 244 may be placed in the vicinity of the pump 212 or pump 212 abut. 取决于具体应用,偏移部分可以配置在泵212的排出侧,吸入侧或者其两侧。 Depending on the application, the offset portion may be disposed on the discharge side of the pump 212, the suction side or both sides thereof. 如果偏移部分是螺旋形的,螺旋型螺旋体可以是向左旋转的或者向右旋转的。 If the offset portion is a helical, spiral helix may be rotated to the left or right rotation. 优选地, 用于管线的特定偏移部分的螺旋型螺旋体的方向与管线的旋转方向匹配以提供将固体颗粒扫向泵212的入口274的螺旋推运行为。 Preferably, the rotation direction of the helical spiral line for a particular line offset portion is matched to provide solid particles down the pump inlet 212 of the auger 274 is running.

[0038] 在另一个具体实施方式中,偏移部分224,244可以是波形的,这样偏移部分的每个纵向轴线是大致平面的。 [0038] In another specific embodiment, the offset portions 224, 244 may be a waveform, so that the longitudinal axis of offset of each section is substantially planar. 在波形或螺旋形构造中,每个偏移部分包括大致非线性的且大致从偏移部分能够围绕旋转的轴线变动的纵向轴线。 In the waveform or helical configuration, each offset portion includes a substantially linear axis and the longitudinal axis of the variation is substantially rotatable about an offset from the portion.

[0039] 如图2所示,第一管线和第二管线216,240的旋转也引起井筒中的泵212的旋转移动。 [0039] As shown in Fig 2, rotation of the first line and the second line 216,240 also causes rotational movement of the pump 212 in the wellbore. 当第一管线和第二管线216,240的旋转停止时,泵212可能会停靠在井筒204的许多不同的位置中的任何一处。 When the first line and the second line 216,240 is stopped rotating, the pump 212 may be docked in many different locations in the wellbore 204 at any point. 在许多情况下,泵212优选位于与较高位置(如图中虚线所示)相对的大致水平部分258的较低位置(如图中实线所示),因为泵212定位于井筒204 的较低位置允许移除较多的液体。 In many cases, the pump 212 is preferably located at a higher position (as shown in broken line) of a substantially horizontal portion 258 opposite a lower position (shown in solid line), since the pump 212 is positioned in a wellbore 204 than low position allows removal of more liquid.

[0040] 参考图4所示,根据例示性具体实施方式的用于控制井408的井筒404内固体颗粒的系统400包括位于井下的泵412。 [0040] Referring to FIG. 4, according to an exemplary specific embodiment of the control system 404 of the solid particles within the wellbore 400 includes a well 408 located downhole pump 412. 第一管线416从井408的地表面420延伸并且可操作地连接到泵412。 The first line 416 extending from the surface of the well 408, and 420 is operatively connected to the pump 412. 在图4所示的具体实施方式中,第一管线416不包括偏移部分。 In the particular embodiment shown in FIG. 4, a first line 416 does not include an offset portion.

[0041] 第二管线440可操作地连接泵412并且从泵412向井下延伸。 [0041] The second line 440 is operatively connected to the pump 412 and 412 extending from the downhole pump. 在一个具体实施方式中,第二管线440包括偏移部分444,在偏移部分444中第二管线440的纵向轴线448从第二管线440的管线旋转轴偏移,第二管线440能够绕管线旋转轴旋转。 In one specific embodiment, the second line 440 includes an offset portion 444, 444 in the offset portion 440 of the second line 448 is offset from the longitudinal axis of the rotary shaft line of the second line 440, second line 440 can be about line axis of rotation. 偏移部分444中的第二管线440的旋转轴大致对应于井筒404的纵向轴线。 Offset rotary shaft portion 444 of the second line 440 corresponding substantially to the longitudinal axis 404 of the wellbore.

[0042] 类似于图2和3的井208,井筒404可以包括大致竖直部分妨4和大致水平部分458。 [0042] similar to Figure 2 and 3 of 208 wells, the wellbore 404 may include a generally vertical portion and a substantially horizontal portion 4 harm 458. 泵412和第二管线440的偏移部分444优选地大致位于井筒404的大致水平部分458 中。 Offset pump 412 and line 440 of the second portion 444 is preferably located substantially in a substantially horizontal wellbore section 404 458. 偏移部分444的擦拭动作类似于参考图2和3所描述的那样,并且第一和第二管线通过位于地表面420的旋转器470进行旋转。 The offset portion 444 of the wiping action similar to Figures 2 and 3 as described, and the first and second line is rotated by the rotator 470 at ground surface 420.

[0043] 在一个具体实施方式中,期望第二管线440的偏移部分444在泵送循环之间只进行简短且间歇地旋转。 [0043] In a specific embodiment, the desired portion of the second line 440 is offset 444 only briefly and intermittently rotated between the pumping cycle. 因为泵412可以邻接于偏移部分444或者在偏移部分444的附近, 泵412遇到与前面描述的相同定位问题。 Because the pump 412 can be adjacent to or in the vicinity of the offset portion 444 of the offset portion 444, the pump 412 is positioned the same problems encountered previously described. 当第一和第二管线416,440的旋转停止时,泵412 可能停靠在井筒404的许多不同位置中的一处。 When the rotation of the first and second line 416,440 is stopped, the pump 412 may be docked in a number of different positions in the wellbore 404. 在许多情况下,泵412优选位于大致水平部分458的与较高位置相对的较低位置(如图4所示),因为泵412定位于井筒404的较低位置允许移除较多的液体。 In many cases, the pump 412 is preferably located in a substantially horizontal portion 458 and the upper position opposite to the lower position (FIG. 4), since the pump 412 is positioned at a lower position of the wellbore 404 to allow removal of more liquid. 测斜器475可以可操作地与第一管线416或泵412关联以提供泵在围绕井筒圆周的圆环形路径内的位置指示。 Clinometer 475 may be operatively associated with the first pipeline 416 or a pump 412 to provide an indication of the position of the pump within the circular path about the circumference of the wellbore. 测斜器475可以电连接到位于地表面420 或者井下的控制系统477,控制系统477能够与转动旋转器470的马达479通信以可选择地定位井筒404中的泵412。 Clinometer 475 may be electrically connected to the ground surface 420 or positioned downhole control system 477, the communication control system 477 capable of turning the rotary motor 479 and 470 to selectively position the pump 412 in the wellbore 404.

[0044] 参考图5,根据例示性具体实施方式的用于控制井508的井筒504内固体颗粒的系统500包括位于井下的泵512。 [0044] Referring to FIG 5, according to an exemplary embodiment of a control system DETAILED within the wellbore 504 508 500 solid particles located downhole comprises a pump 512. 第一管线516从井508的地面520延伸并且可操作地连接到泵512。 The first line 516 extends from the surface 520 of the shaft 508 and operatively connected to a pump 512. 第二管线540可操作地连接到泵512并且包括类似于前述的那些偏移部分的偏移部分。 The second line 540 is operatively connected to the pump and includes an offset portion 512 similar to those of the offset portion.

[0045] 泵512是电动潜水泵。 [0045] pump 512 is an electric submersible pump. 旋转器570位于地表面520以转动第一和第二管线516, 540以及泵512。 Rotator 570 located on the ground surface 520 to rotate the first and second lines 516, 540 and a pump 512. 具有计时器的控制单元590与可操作地连接到旋转器570的马达591进行通信。 A timer control unit 590 is operatively connected to the rotary motor 591,570 communicate. 控制单元590也通过泵缆线592或其他通信线路与泵512通信。 The control unit 590 also communicate through a pump 592 or other communication cable line and the pump 512. 虽然泵缆线592 能够位于第一管线516的外侧时,但在图5所示的具体实施方式中,泵缆线592位于第一管线516内以防止泵缆线磨损或毁坏。 Although the pump 592 when the cable 516 can be positioned outside of the first line, but in the particular embodiment shown in FIG. 5, the cable 592 is located in the pump to prevent the pump cable wear or destruction of the first line 516. 泵缆线592可以使用类似前面描述的方法和系统输送到井下。 Pump cable 592 may be used similar to the methods and systems previously described delivery downhole.

[0046] 参考图6A-6E,提供根据例示性具体实施方式的缆线输送系统608,用于将缆线612输送到定位于井618的井筒616内的井下位置614处的井下设备。 [0046] with reference to FIGS. 6A-6E, provides a cable delivery system according to an exemplary embodiment 608 of the particular embodiment, transmission cable 612 for location to the downhole apparatus 614 is positioned downhole in the wellbore 616 in a well 618. 在图6A-6E所例示的具体实施方式中,井下设备是泵620,缆线612是给泵620提供电力的电缆线。 In FIGS. 6A-6E illustrated embodiment, the downhole device is a pump 620, cable 612 is a cable to provide power to the pump 620. 缆线612 的输送发生在泵620进入井616内之后且在管线624的一个端部流体地连接到泵620时。 Cable 612 occurs after delivery of the pump 620 into the well 616 and connected to a pump 620 in a line 624 is fluidly end time. 在安装了管线6M和泵620之后,缆线612被安装在管线624内,这将在下面详细描述。 After the line 620 and the pump 6M installation, the cable 612 is installed in line 624, which will be described in detail below. 泵的安装和移除过程通过以这种方式输送缆线612而大大简化了,因为同时处理管线和缆线612的耗时过程取消了。 Pump installation and removal through the transmission cable 612 in this manner greatly simplified since the pipeline processing while consuming process and the cable 612 is canceled. 另外,通过将缆线612安装在管线624内,缆线612受到保护以免毁坏。 Further, by mounting the cable 612 in line 624, cable 612 protected from destruction.

[0047] 缆线输送系统608包括插塞6¾和接收器632。 [0047] The delivery system 608 includes a cable plug 632 and a receiver 6¾. 更具体地参考图6B,插塞6¾包括适于装配在管线624内的插头壳体640使得插塞拟8能够在管线624内纵向移动。 More specifically, with reference to Figure 6B, comprises a plug adapted to fit 6¾ plug housing 624 in the line 640 such that the plug 8 can be moved longitudinally proposed in line 624. 插头壳体640包括连接到应变消除构件648的导向构件644。 The plug housing 640 includes a strain relief connected to the guide member 644 of member 648. 导向构件644可以是大致圆筒形的形状并且在尺寸方面紧配合管线624的内径。 The guide member 644 may be substantially cylindrical shape and is a tight fit in the inner diameter of line 624 dimensions. 导向构件644的外地表面可以由弹性材料制成并且可以包括波纹,波状起伏,或其他类似的不规则地表面以提供与管线624的接触点652。 Field surface of the guide member 644 may be made of an elastic material and may comprise corrugations, undulations, or other similar irregular surface to provide a contact point 652 to line 624. 大量的接触点652确保插头壳体640能够充分地限制流体流过插头壳体640,却使得接触管线624的地表面积最小,这改善了插头壳体640在管线624内滑动的能力。 A large number of contact points 652 to ensure that the plug housing 640 can sufficiently restrict fluid flow through the plug housing 640, but the minimum surface area of ​​the contact line 624, which improves the ability of the plug housing 640 to slide in line 624.

[0048] 应变消除构件648包括用于接收缆线612的缆线通道654。 [0048] The strain relief member 648 includes a cable 612 for receiving cable channel 654. 可以使用一个或多个螺栓656,螺钉或其他紧固件以将缆线紧固到应变消除构件648上。 You may use one or more bolts 656, screws or other fasteners to fasten the cable to the strain relief member 648. 在图6B所示的具体实施方式中,缆线612是双股缆线并且包括一对单独地绝缘的电线658。 In the particular embodiment shown in FIG. 6B, the cable 612 is a twinax cable 658 and includes a pair of individually insulated wires. 每根电线658通过排出口660并且被紧固到电线接头662。 Each of the wires 658 through the discharge port 660 and fitting 662 is secured to the wire. 每个电线接头662电连接到导电体664。 Each wire connector 662 is electrically connected to the conductor 664.

[0049] 插塞6¾包括允许流体流过插头壳体640的通道668。 [0049] The plug comprises 6¾ allow fluid flow through passage 668 of the plug housing 640. 通道668延伸穿过导向构件644和应变消除构件648。 Passageway 668 extending through the guide member 644 and the strain relief member 648. 诸如单向或止回阀的阀670可操作地关联到通道668以限制流体向井下方向流过通道648并且允许流体向井上方向流过通道668。 670 operatively associated with a valve such as a one-way or check valve to the passageway 668 to restrict fluid flow through the passage 648 and the downhole direction 668 allows fluid to flow through passage uphole direction. 阀670包括阀座672 和阀体674。 Valve 670 includes a valve seat 672 and a valve body 674. 阀体包括中心区域676,上肩区域678和下肩区域680。 The valve body includes a central region 676, region 678 and a shoulder 680 lower shoulder region. 中心区域676可以是大致圆筒形的并且由阀座672滑动地接收。 The central region 676 may be substantially cylindrical and is slidably received by the valve seat 672. 阀通道684贯穿阀体的674的上肩区域678,中心区域676和下肩区域680。 Shoulder area of ​​the valve passage 684 through 678 of the valve body 674, a central region 676 and a lower shoulder 680 region. 多个口686布置在阀中心区域676以与阀通道684连通。 A plurality of ports 686 arranged in communication with the valve passage 684 in the central region of the valve 676.

[0050] 阀体674在阀座672内的纵向运动受到上肩区域678和下肩区域680的限制。 [0050] The longitudinal movement of the valve body 674 in the valve seat 672 is limited by shoulder 678 and the lower region 680 of the shoulder area. 阀体674能够在阀座672内在打开位置(未例示)和关闭位置之间(参见附图6B)滑动。 Valve element 674 to open position (not illustrated) and a closed position (see FIG. 6B) to slide in the inner valve seat 672. 当出现插塞628的井上流体所具有的压力高于插塞628的井下流体的压力时达到关闭位置。 Reaches the closed position occurs when fluid uphole of the plug 628 has a pressure higher than the pressure of fluid downhole plug 628. 在关闭位置,多个口686与阀座672对齐,其阻止插塞6¾的井上流体流过通道668和阀通道684。 In the closed position, a plurality of ports 686 is aligned with the valve seat 672, which prevents the plug uphole fluid flow through 6¾ valve passage 668 and passage 684. [0051 ] 为了便于从井里移除缆线612和插塞628,压力安全装置690位于阀体674的上肩区域678中的阀通道684内。 [0051] In order to facilitate removal of the cable from the well 612 and the plug 628, the pressure on the security device 690 is located within the shoulder region 678 of the valve body 674 in the valve passage 684. 在图6B所示的具体实施方式中,压力安全装置690是构造成在预定压差时失效的爆破膜。 In the particular embodiment shown in FIG. 6B, a pressure safety device 690 is configured as a bursting disc failure when a predetermined pressure differential. 当插塞628的井上流体的压力小于压力安全装置690的设定压力时,阻止流体流过上肩区域678附近的阀通道684。 When the plug 628 is uphole fluid pressure is less than the set pressure of the safety device 690, close to prevent fluid flow through the valve passage 678 on the shoulder 684 region. 在这种情况下,只有阀体674移动到打开位置时,流体才能流过阀通道684。 In this case, only the valve element 674 moves to the open position, fluid can flow through the valve passage 684. 然而,当插塞628的井上流体的压力超过压力安全装置690的设定压力时,爆破膜将破裂,因此允许流体流过阀通道684,即使阀体674处于关闭位置。 However, when the set pressure of the plug 628 uphole fluid pressure exceeds the pressure safety apparatus 690, the bursting disc will rupture thus allowing fluid flow through the valve passage 684, even when the valve element 674 is in the closed position.

[0052] 需要着重指出的是,安全装置690可以是更传统的、能够重复使用的安全阀。 [0052] It is important to point out that the safety device 690 may be more conventional, the valve can be reused. 安全阀可以与阀体674或插头壳体640可操作地关联,以便当插塞628的井上流体的压力等于或超过压力安全装置的设定压力时允许流体流过通道668。 Allow fluid flow through passage 668 when the valve 640 may be operatively associated with the valve body or plug housing 674, so that when the plug 628 is uphole fluid pressure equals or exceeds the set pressure of the safety device.

[0053] 更具体地参考图6C,图6C例示了另一具体实施方式的插塞700,其包括那些参照插塞拟8所讨论的类似于部件。 [0053] Referring more particularly to FIG. 6C, FIG. 6C illustrates another particular embodiment inserted plug 700, which comprises means 8 similar to those discussed with reference to plug intended. 图6B中所例示的相同的附图标记用来说明类似的部件。 The same reference illustrated in FIG. 6B for explaining the mark like parts. 插塞700和插塞6¾之间的主要区别是插塞700包括球状物704和阀座672布置。 The plug 700 and the plug is the main difference between 6¾ plug 700 comprises a ball 704 and seat 672 are arranged. 流体流过通道668是由球状物704移入且接触阀座672和移出且解除与阀座672的接触来控制的。 Fluid flow through the passage 668 by the ball 704 is moved into and out of contact with the valve seat 672 and valve seat 672 and is in contact with the release controlled. 关于插塞700的另一个区别是不存在压力安全装置;但是,应该指出的是类似于上面描述的安全阀能够与插头壳体640联合使用。 Another difference on the plug 700 is a pressure safety device is not present; however, it should be noted that the relief valve similar to that described above can be used in combination with the plug housing 640.

[0054] 更具体地参考图6D,接收器632位于井的井下位置614。 [0054] Referring more particularly to 6D, the receiver 632 located at a downhole location in the well 614. 虽然图6D中所例示的井下位置614位于井618的水平部分内,井下位置614以及由此泵620和接收器632的位置可替代地位于井618的垂直部分内。 Although the downhole location shown in FIG. 6D Example 614 located within the horizontal portion of the well 618, 614 and thus the position of the downhole pump 620 and the position of the receiver 632 may alternatively be located within the vertical portion of the well 618. 接收器632包括可以位于管线6M和泵620之间的接收器壳体740。 The receiver 632 comprises a receiver housing may be located between the pump line and 6M 620,740. 在图6D所例示的具体实施方式中,接收器632通过连接器742连接到管线624。 In FIG. 6D illustrated embodiment, the receiver is connected to the line 632,742 through the connector 624. 接收器632可以螺纹连接地(threadingly)连接到泵620。 The receiver 632 may be a threaded connection (threadingly) connected to the pump 620.

[0055] 接收器壳体740包括用于接收与泵620电连通的电跨接线755的缆线通道754。 [0055] The receiver 740 comprises a housing for receiving electrical communication with the pump 620 electrical jumper cable channel 755 754. 类似于缆线612,跨接线755是双股电缆并且包括一对单独绝缘的电线758。 Similar to cable 612, jumper 755 is a twinax cable and comprises a pair of individually insulated wires 758. 电线758各自终接在导电体764处。 Each wire 758 terminating at the conductive body 764.

[0056] 接收器632包括通路768以允许在管线拟4和泵620之间流体连通。 [0056] The receiver 632 includes a passage 768 to allow fluid communication between the line 620 and the pump 4 intended. 诸如单向阀或者止回阀的阀770与通路768可操作地关联以限制流体向井下方向流过通路768并且允许流体向井上方向流过通路768。 Such as one-way valve or check valve 770 and associated passageway 768 is operable to restrict fluid flow through the passageway 768 and allow the downhole fluid to flow through passage 768 to the uphole direction. 阀770包括阀座772和阀体774。 Valve 770 includes a valve seat 772 and the valve body 774. 流体流过通路768是通过阀体774移入且接触阀座772或移出且解除与阀座772的接触来控制。 Fluid flow through passage 768 and through the valve body 774 into contact with the valve seat 772 and out of contact with the valve seat 772 and the release is controlled. 阀体774可以是如图6D所示的大体球状的形状,或者可以是能够适合与阀座密封的任意其他形状。 Valve 774 may be a substantially spherical shape as shown in FIG. 6D, or can be sealed with the valve seat can be adapted to any other shape.

[0057] 阀体774能够在打开位置(未例示)和关闭位置(参见图6D)之间移动。 [0057] The valve element 774 can be (not illustrated) movable between an open position and a position (see FIG. 6D) closed. 当出现接收器632的井上流体所具有的压力大于接收器632的井下流体的压力时到达关闭位置。 Inoue occurs when the receiver 632 has a fluid pressure greater than the receiver 632 of the downhole fluid pressure reaches the closed position. 当接收器632的井下流体的压力超过接收器632的井上流体的压力时,阀体774移动到打开位置。 When the fluid pressure downhole receiver 632 exceeds the fluid uphole of the receiver 632, the valve body 774 moves to the open position. 在打开位置中,流体在泵620和管线6¾之间能够连通,因而为由泵620排出的流体提供了路径。 In the open position, fluid communication is possible between the pump 620 and line 6¾, thus by the fluid pump 620 provides a discharge path.

[0058] 接收器安全阀790与接收器壳体740可操作地关联,以便当通道768中的流体压力达到或者超过接收器安全阀790的设定压力时允许通道768和形成于管线7M和井筒616间的环形空间769之间流体连通。 [0058] Receiver valve 790 associated with the receiver housing 740 is operable to allow the passage 768 and is formed when the fluid pressure in the passage 768 reaches or exceeds the set pressure of the safety valve the receiver 790 in the wellbore and the pipeline 7M fluid communication between the annular space 616 to 769. 当通道768中的流体压力小于接收器安全阀790的设定压力时,接收器安全阀790将阻止在通道768和环形空间769之间流体连通。 When the fluid pressure in passage 768 is less than the set pressure of the safety valve the receiver 790, the receiver 790 valve 769 will prevent fluid communication between the passage 768 and the annular space.

[0059] 仍然参考图6A-6E,在操作时,缆线612是通过将插塞6¾和缆线612 “泵送”到管线拟4下而安装的。 [0059] Still referring to FIGS. 6A-6E, in operation, the cable 612 by the cable 612 and plug 6¾ "pumped" into the line 4 at the intended installation. 更具体地,加压流体通过插头壳体640后面的或插塞壳体640的井上的泵795引入以推动插头壳体640下到管线624。 More specifically, the pressurized fluid through the back of the plug housing 640 or plug uphole to the pump housing 640 of the housing 795 to push plug 640 is introduced into line 624. 当插塞6¾必须行进于井618的并不竖直的部分时给插塞6¾提供这个力是必需的。 When the plug is not vertical portion 6¾ must travel to the well plug 618 6¾ provide this force is required. 缆线612可以通过位于井618(参见图6A) 的地表面的线轴665和滑轮系统667提供给井618。 Cable 612 may be provided to the well 618 through a pulley system 665 and the spool 618 is located in the well (see FIG. 6A) of the surface 667.

[0060] 在将插塞6¾泵送到井6¾下之前,管线6¾可以充满流体以控制插塞6¾和缆线612的下降。 [0060] Before the plug 6¾ pumped downhole 6¾, 6¾ may be filled with a fluid line to control the drop and the cable plug 612 6¾. 接收器安全阀790的设定压力大到足以支承从井618的地表面延伸到接收器632的管线624中的整个流体柱的重量再加上推动插塞628的缆线的静重。 The receiver pressure relief valve 790 is set large enough to support 618 extending from the surface of the well to the entire weight of the fluid column line receivers 624,632 in pushing the plug 628 coupled with the dead weight of the cable.

[0061] 在流体充满管线6M后,插塞6¾可以插入到位于井618的地表面处的管线6M 中并且流体压力作用到插塞6¾后面以泵送插塞628。 [0061] After the fluid fills the pipeline 6M, 6¾ plug may be inserted into the well located at the surface of 6M line 618 and the fluid pressure behind the plug 6¾ to pump the plug 628. 在插塞的井上或者后面施加流体压力增加插塞和接收器之间的流体压力,因而超过接收器安全阀790的设定压力点并且打开接收器安全阀790。 Applying fluid pressure increases the fluid pressure between the plug and the receiver in the uphole or behind the plug, and thus the set pressure of the relief valve exceeds a receiver point 790 and opens the receiver valve 790. 随着接收器安全阀790的打开,插塞6¾和接收器632之间的流体从管线6¾排进环形空间769。 With the receiver of the relief valve 790 opens, the plug 632 is inserted between the receiver and the 6¾ fluid from the discharge line into the annular space 769 6¾. 优选地,管线中的流体是不可压缩的,例如水,并且这种不可压缩的流体通过接收器安全阀790的释放允许插塞6¾受控地下降到接收器632。 Preferably, the pipeline is incompressible fluid, such as water, and this incompressible fluid is released through the receiver valve plug 790 permits controlled 6¾ drops to the receiver 632.

[0062] 当插塞6¾到达井下位置614和接收器632时,插塞628的井上管线624中聚积的流体(即,已经通过泵795泵送到插塞6¾后面的管线624中的流体)推动插塞6¾使其与接收器632接合。 [0062] When the plug 632 reaches 6¾ plug 624 628 Inoue line accumulated fluid downhole location and a receiver 614 (i.e., the back of the plug has been inserted to 6¾ fluid in line 624 by a pump 795 pumps) driven 6¾ plug 632 engage it with the receiver. 插塞6¾和接收器632之间的接合使得导电体664与导电体764紧密配合。 6¾ plug and a receiver 632 such that the engagement between the conductor 664 and the conductor 764 mate. 可以使用可拆卸的锁定机构以在泵工作期间保持接合。 You can use a removable locking mechanism to remain engaged during pumping. 导电体664,764之间的接触允许电连通,由此将缆线612联结到泵620。 The contact between the conductors 664,764 allow electrical communication, whereby the cable 612 coupled to the pump 620. 随着缆线612的输送,缆线612可以连接到井618的地表面的电源(图中没有显示)以给泵提供电力。 With the transmission cable 612, the cable 612 may be connected to a power supply ground surface of the well 618 (not shown) to provide power to the pump.

[0063] 当泵工作时,从泵620排出的流体使阀体774和阀体674移动到打开位置,这允许排出的流体流经管道768,管道668和管线6¾到达井618的地表面。 [0063] When the pump is operated, fluid discharged from the pump 620 and valve 674 the valve body 774 moves to the open position, which allows fluid to flow through the discharge conduit 768, conduit 668 and reaches the surface of the well 6¾ line 618. 当泵620停止工作时,任何聚集在插塞6¾和接收器632上方的管线624中的流体由移动到关闭位置的阀体674来阻止回流。 When the pump 620 is stopped, any aggregates in the fluid line is inserted over plug 624 632 6¾ and the receiver to the closed position by the valve body 674 to prevent backflow.

[0064] 在深井中,通过简单地拉动缆线使插塞6¾与接收器632脱离,这如果不是不可能的,也是非常困难的。 [0064] In deep wells, by simply pulling the cable so that the plug 632 from the receiver 6¾, which if not impossible, is very difficult. 如果插塞6¾上方的流体柱对插塞6¾施加足够的力,这个力可以超过缆线的强度。 If the plug of the fluid column above the 6¾ applying sufficient force to the plug 6¾, this force may exceed the strength of the cable. 在这种情况下,在接收器632和插塞拟8脱离之前,插塞拟8的井上流体可以从管线中排干。 In this case, before the receiver 632 and the plug 8 from the quasi plug intended uphole fluid 8 may be drained from the pipeline. 在一个具体实施方式中,将诸如水的流体泵入管线624以便当缆线612 和插塞6¾从井618中拉出来时引起爆破膜690失效并且允许截流在插塞6¾上方的流体流过插塞。 In one specific embodiment, the fluid pump, such as water, into the line 624 such that when cable 612 and a plug 690 6¾ cause bursting disc when pulled out of the well 618 fails and the plug closure allows fluid flow through the top plug 6¾ plug. 在另一具体实施方式中,诸如空气的低密度流体被泵入管线,使堵在插塞上方的高密度流体通过安全装置690和接收器安全阀790转移。 In another specific embodiment, the low density fluid such as air is pumped into the pipeline, so that plug 790 is transferred through the safety valve means 690 and the receiver in the high density fluid above the plug.

[0065] 虽然图6A-6E中例示的具体实施方式主要指向将电力缆线输送给电动潜水泵,这里所描述的缆线输送的系统和方法可以应用到电力缆线,数据传输缆线,光纤维缆线或者用于井下的其他任何缆线。 [0065] Although in FIGS. 6A-6E illustrate specific embodiments will be mainly directed to the electric power cable delivery submersible pump, a cable conveying systems and methods described herein may be applied to the power cable, a data transmission cable, optical fiber cable or any other cable downhole. 如果使用光纤维缆线,设有插塞和接收器的导电体可以用被用于与光缆接头相媲美的适当部件替换。 If the optical fiber cable with a plug and a receiver may be replaced with an appropriate conductive member is comparable with a cable connector. 类似地,缆线被输送到的井下设备不仅局限于电动潜水泵。 Similarly, cable is conveyed to a downhole electric submersible pump apparatus is not limited. 其他设备可以包括有线测井设备,阵列传感器,钻孔马达,或者在井下环境中需要输送电力或数据的其他任何设备。 Other devices may include wired logging apparatus, an array of sensors, drilling motors, downhole environment or in any other device needs to be delivered power or data.
