摘要： Selective and non-selective lock mandrel assemblies include a lock mandrel affixing to a running tool. A collet on the tool holds an inner mandrel in a downhole position in the lock mandrel. For the non-selective assembly, a biased key on the lock mandrel extends into a nipple profile, and shoulders on the key and profile stop further run-in. Operators shear a first shear pin on the running tool by jarring down, and the collet moves and releases its hold on the inner mandrel. Freed, the inner mandrel biased by a spring moves to an uphole position, and a flange fits behind the extended key to lock it in the profile. For the selective assembly, the biased key is held retracted until activated using locator dogs on the running tool to engage a transition when running uphole. Once the lock mandrel is set, operators detach the running tool from it.

摘要： Operators manufacture a wellscreen by forming a wire-wrapped screen on a base pipe. Rather than stopping and restarting winding, the desired length of screen is completed along the base pipe, and then the wire screen is segmented into a plurality of screen sections as required for the various zones and details of the implementation. Operators arrange the screen sections relative to one another on the base pipe, which can have different lengths with and without perforations. On the free ends of these separate screen sections, mating split ring components fit around the free ends and the base pipes. Male edges of one split ring component mate to complementary female edges of another to form the end ring around the screen section and base pipe, and longitudinal welds made in seams along the mating edges affix the split ring components together.

摘要： Methods and apparatus enable reliable and improved isolation between two portions of a bore extending through a casing string disposed in a borehole. A downhole deployment valve (DDV) may provide the isolation utilizing a valve member such as a flapper (2002) that is disposed in a housing (2006) of the DDV and is designed to close against a seat (2114) within the housing. The DDV includes an operating mechanism for blocking/unblocking the valve member. In use, pressure in one portion of a well that is in fluid communication with a well surface may be bled off and open at well surface while maintaining pressure in another portion of the casing string beyond the DDV.

摘要： A backspin retarder for a progressive cavity pump deploys on the drive string uphole from a pump unit. The backspin retarder has a shaft that connects to portions of the drive string. An impeller disposes on the shaft and can move axially and radially. In an unengaged condition, the impeller and shaft can rotate relative to one another so the drive string can rotate in a drive direction without impediment from the impeller. In an engaged condition, the impeller rotates with the shaft in a backspin direction. In this way, vanes on the impeller can retard the backspin of the shaft and drive string by attempting to force the lifted fluid column flowing downhole past the impeller back uphole. The retarder can use a pin and slot arrangement or an arrangement of engageable teeth to engage the impeller to the rotation of the shaft.
摘要翻译：用于渐进式空腔泵的反向延迟器部署在从泵单元向上钻孔的驱动串上。后旋减速器具有连接到驱动串的部分的轴。叶轮配置在轴上并可以轴向和径向移动。在未接合状态下，叶轮和轴可以相对于彼此旋转，使得驱动串可以在驱动方向上旋转而不受叶轮阻碍。在接合状态下，叶轮以轴旋转方向旋转。以这种方式，叶轮上的叶片可以通过试图迫使提升的流体柱在井下通过叶轮回到井上来阻止轴和驱动柱的后倾。延迟器可以使用销和槽布置或可啮合齿的布置以将叶轮接合到轴的旋转。
