摘要： A first wireline tool embodiment includes a segmented tool body having a joint deployed between each adjacent pair of tool body sections. The joint may be configured to extend axially (causing a relative axial displacement of the adjacent tool body sections) when the wireline tool is subject to an axial load. The joint may include, for example, a compliant joint or a protractible joint. The joint may be further configured to cause a relative rotation between the adjacent tool body sections when the wireline tool is subject to axial load. A second wireline tool embodiment includes a plurality of standoff rings deployed about an outer surface of a rigid tool body. The standoff rings engage helical grooves in the outer surface of the tool body such that axial displacement of the tool body causes the standoff rings to rotate.

摘要： A method of freeing a pipe stuck in a subterranean well can include determining a location of a portion of the pipe stuck in the well, and penetrating and/or heating a sidewall of the pipe portion with a beam of light. A system for freeing a pipe stuck in a subterranean well can include a tool deployed into a portion of the pipe stuck in the well by a differential pressure from a wellbore to a formation penetrated by the wellbore. A beam of light emitted from the tool penetrates the pipe portion. Another method of freeing a pipe stuck in a subterranean well can include determining a location of a portion of the pipe which is biased against a wall of a wellbore by differential pressure, and directing a beam of light to the pipe portion.

摘要： A debris removal device for subterranean use features a debris laden inlet tube within a housing to define a debris collection space at the lower end of the housing. An eductor draws the debris laden fluid to the top of the inlet tube where the flow stream is returned to a downhole direction with discrete passages formed between the housing and the inlet tube by spaced parallel plates. The plates feature extending tabs on diametrically opposed lower ends of the plates. As a result flow heading back downhole can release debris and turn back uphole in passages defined between the outside of the plates and the inside wall of the housing. The tabs allow the flow turning uphole to make a greater radius turn because of a crossing over effect created by the tabs. There is less turbulence and narrower width to the flowing stream going uphole.
摘要翻译：用于地下使用的碎片去除装置在壳体内具有载满碎屑的入口管，以在壳体的下端限定碎屑收集空间。喷射器将载满碎屑的流体抽吸到入口管的顶部，其中流动流返回到井下方向，并且通过间隔开的平行板在壳体和入口管之间形成分离的通道。板的特征在于板的直径相对的下端具有延伸的突出部。结果，向下返回到井下的流动可以释放碎屑并在通过限定在板的外部和壳体的内壁之间的通道中向后回转。由于标签产生的交叉作用，这些突片允许流向上的孔进行更大的半径转弯。流向井的流动的波动较小，宽度较窄。

摘要： A subterranean debris catcher swirls the incoming debris laden stream by putting grooves or spiral projections on the inside of the inlet pipe. In some embodiments the solids come out of openings in the side of the inlet pipe and in others the solids can exit near the top either directly into the enclosed solids holding volume as the liquid exits straight out or the solids can be discharged out the end of the inlet pipe into the bigger open space defined by the housing. In the latter case the inside housing wall can have a screen or vanes that slow down the solid particles as the fluid continues to a housing exit and eventually to an exit screen before being discharged to either go to the surface or recirculate back along the outside of the tool to the inlet pipe while picking up additional debris.

摘要： A combination tool is delivered to compacted debris above a packer whose plug is to be removed. The shoe or mill is on the lower end of an outer bushing and the grapple or overshot is held within the bushing but away from the shoe so that the shoe can advance into the debris as reverse circulation takes the cuttings up through a mandrel to a debris removal tool. When the shoe lands on the packer the surface personnel can see it on the weight indicator. Weight is then set down to overcome a resisting force of a breakable member such as a shear pin or a spring or both so that the grapple advances to engage the packer plug. Advancing the mandrel relative to the bushing with the shoe at its lower end also releases a torque lug that previously allowed tandem rotation of the mandrel with the bushing.

摘要： A selectably operable passive gripping device for gripping tubular materials has an elastomeric element which is provided with integrally bonded segmented end rings to prevent the extrusion of the elastomer when it is subjected to high compressive loads. The elastomeric element is molded so that its as-molded gripping surface interferes with the surface of tubular objects to be gripped. The elastomeric gripping element is mounted and supported by a structural element or housing and allows axial flow communication through the gripped tubular objects. The gripping device is used to lift tubular objects such as a tubular string used in oil field applications.
