摘要： Well completion cement may be pumped through a side pocket mandrel that includes parallel rows of filler sections to exclude cement from void space within the side pocket tube. The filler sections are drilled with cross-flow jet channels and surface upsets to stimulate scrubbing turbulence by well working fluid behind a cement wiper plug. The wiper plug includes leading and trailing groups of wiper discs secured to an elongated shaft. The two wiper groups are separated by a distance that permits the leading seal group to gain traction seal before the push seal on the trailing wiper group is lost. A spring centralizer spans a center section of the shaft between the two wiper groups to maintain axial alignment of the shaft as the plug traverses the length of a mandrel.
摘要翻译：完井水泥可以通过包括平行的填料段的侧袋心轴泵送，以从侧袋管腔内的空隙排除水泥。填充部分钻有横流喷射通道和表面扰动，以通过水泥刮水器插头后面的井下工作流体刺激洗涤湍流。刮水器插头包括固定到细长轴上的雨刷盘的前后组。两个刮水器组分开一段距离，允许前导密封组在拖把组件的推压密封件丢失之前获得牵引密封。弹簧对中器跨越两个擦拭器组之间的轴的中心部分，以在塞子穿过心轴的长度时保持轴的轴向对准。

摘要： An insert device can straddle an existing production string port into the annulus such as through an open sliding sleeve so that annulus access into the production string is available. An injection string is associated with the insert to allow placement of the injection fluid at the desired location even if that location is below an isolation packer. The port can be part of an existing ported sub such as a sliding sleeve. Alternatively, the port can be created at a desired location and the insert supported with an anchor so that spaced seals straddle the port that is created to allow injection access from the annulus into the production tubing. The produced fluids pass around the injection tubing and through the insert body to get to the surface. The insert can be removed if needed.

摘要： A side-pocket gas lift mandrel having tapered end caps threaded onto the ends of the mandrel with metal-to-metal sealing threads. The thickness of each made up thread set is the same as the thickness of the small end of each end cap, resulting in a mandrel having the same outside diameter as if the end caps were welded on, without sacrificing any inside diameter in the small ends of the end caps, compared to a welded mandrel.

摘要： Improved inserts for use in side pocket mandrels which include one or more annular sealing elements that are formed of an elastomeric material that swell in response to heat or fluid saturation. When the insert is emplaced within a side pocket mandrel, the swellable elastomer can then be swelled, using either heat or fluid saturation, to cause the sealing element(s) to expand and seal against the seal bore of the side pocket mandrel.

摘要： Gas lift valve designs and gas lift systems are described that feature a positive closure mechanism that is highly resistant to significant wear or damage that would result in fluid leakage. A pivotable flapper member is incorporated into a gas lift valve and used as a flow control mechanism. The flapper member provides a positive barrier to fluid flow from the production tubing to the annulus, even after substantial wear or damage.

摘要： A valving device includes a tubular having a wall including a passageway therethrough fluidically connecting an outside of the tubular with an inside of the tubular, a plug movable relative to the wall between a first position wherein the plug substantially prevents fluid flow through the passageway and a second position wherein the plug permits fluid flow through the passageway. At least one force failing member configured to maintain the plug in the first position until attainment of a selected force acts upon the plug, and movement of the plug is in a direction substantially parallel to a longitudinal axis of the tubular yet non-coaxial with the tubular.
