摘要： Latch position indicator systems remotely determine whether a latch assembly is latched or unlatched. The latch assembly may be a single latch assembly or a dual latch assembly. An oilfield device may be positioned with the latch assembly. Non-contact (position), contact (on/off and/or position) and hydraulic (flowmeter), both direct and indirect, embodiments include fluid measurement systems, an electrical switch system, a mechanical valve system, and proximity sensor systems.

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. The solids come out of openings in the side of the inlet pipe or 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 polish rod seal comprising: a post with a bottom end, top part, and circumferential flange situated between the bottom end and top part; a collar that fits over the top part of the post, the collar having one or more internal channels into which O-rings are inserted and positioned between the collar and top part of the post; and a barrel with a bottom end and two internal bushings, each of which has one or more internal channels into which O-rings are inserted. The bottom end of the barrel screws into the top part of the post. A bracket is attached to the circumferential flange and secures the collar on the top part of the post while still allowing it to flex on the post. A polish rod extends through the post, collar and barrel and is in contact with the O-rings in the internal bushings.

摘要： A wellbore sealing assembly can include a sealing ring, an energizing ring, and a multifunctional key for engaging the sealing ring and the energizing ring. The multifunctional key can have a key body, a guide member, and a retainer stud. The key body can be located in an aperture in a sidewall of the sealing ring and the guide member and retainer stud can protrude through the sidewall into a guide slot and recess of the energizing ring. Downward force on the energizing ring can cause the retainer stud to shear away while the guide member travels in the guide slot to prevent rotation of the energizing ring relative to the sealing ring. The guide member can also aid in complete seal retrieval by locking against the bottom of the key-way slot in the energizing ring.
摘要翻译： 井筒密封组件可以包括密封环，激励环和用于接合密封环和激励环的多功能键。 多功能键可以具有键体，引导构件和固定螺柱。 键体可以位于密封环的侧壁中的孔中，并且引导构件和保持器螺柱可以通过侧壁突出到通电环的引导槽和凹部中。 激励环上的向下的力可导致保持器螺柱在引导构件在引导槽中行进时剪切，以防止激励环相对于密封环的旋转。 引导构件还可以通过锁定在通电环中的键槽的底部来帮助完全密封回收。

摘要： The dual stripper device of the invention has a hollow body formed for coaxial connection to the wellhead which provides for unobstructed passage of a slick cable, such as a data transmitting cable which transmits data in real time to the well surface. Disposed coaxially within the hollow body is a resilient wiper element with an internal bore formed along its longitudinal axis for passage of the slick cable. A hydraulically actuated piston applies a compressive force to the wiper element so that a pressure seal is formed between the wiper element and the cable when the wiper element is sufficiently compressed by the piston. The seal can be maintained during dynamic movement of the slick cable through the wiper element. A mirror image backup wiper assembly can be actuated in the case of failure of the first wiper assembly.
