摘要： A shock absorbing system has a nose assembly that is formed to inwardly collapse on impact and is guided by a sleeve that can slide with the nose as the nose collapses or can extend for a portion of the length of the nose while being held fixed. In the latter instance the nose can have a leading end that has a biasing member in a resilient material so that on impact some of the shock is taken up by compression of the biasing member with subsequent extension of the biasing member retracting the resilient covering so that it is less likely to bind in the surrounding tubular. The leading end of the sleeve or the resilient material encasing the biasing member also soften the blow to a closed ball when the tool is dropped so that the ball surface is less likely to mar.
摘要翻译：冲击吸收系统具有鼻部组件，其形成为在冲击时向内折叠，并且由套筒引导，套筒可随着鼻子塌陷而与鼻子滑动，或者可以在保持固定的状态下延伸一部分长度的鼻子。在后一种情况下，鼻子可以具有前端，其具有弹性材料中的偏置构件，使得在冲击时，通过偏压构件的压缩来吸收一些冲击，随后偏置构件随后延伸缩回弹性覆盖物，使得在周围的管中不太可能结合。当工具下落时，套筒的前端或包围偏置构件的弹性材料也会使打击成为闭合的球，从而不太可能损坏球表面。

摘要： A position monitoring system includes a tubular with a cavity formed therein, a magnet movable relative to the tubular, and a sensor sensible of a magnetic field of the magnet. A housing positioned within the cavity sealably isolates the sensor from environmental properties while permitting the sensor to sense the magnetic field of the magnet.

摘要： A ball type downhole barrier valve capable of bidirectional sealing features a ball rotating on its axis to open or close with control line pressure to an actuating rod piston assembly. The ball is also shiftable to a locked open position. A cage surrounds the ball and retains opposed seats to it. The cage is made from one piece and tangential holes are drilled and tapped before the piece is longitudinally split with a wire EDM cutting technique. Fasteners to rejoin the cut halves properly space them to the original one piece internal dimension. Auxiliary tools allow determination of spacing of internal components so that a desired spring preload on the seats against the ball can be achieved. Seals on the sleeves that form ball seats help prevent leakage due to ball distortion at high differential pressures when the valve is closed.

摘要： An improved control system, particularly useful for SSVs, is disclosed. It is responsive to a rupture of the tubing and control line to equalize pressure on an operating piston to allow the SSV to go to its failsafe position. The annulus pressure-sensing feature can be employed with a variety of control systems, a particular one is used as an example.

摘要： A flapper base provides a flapper base body with a hinge portion unitarily formed thereupon and a flapper seat surface formed within the flowbore of the body. The flapper base may be formed from a single section of tubular metallic stock. In a method of forming a base, the stock is gripped by a rotary clamp, and a five-axis milling machine is used to cut away portions of the stock section and to form the seat surface.

摘要： A downhole ball valve is mounted n a string and features a rotating ball that turns on its axis as it is held against an upstream and a downstream seal by a cage. The cage accepts a slide that engages the ball off-center to rotate it between the open and closed positions. The slide is operated by a sleeve attached to a piston assembly. The sleeve is mechanically operated in opposed directions such as by a wireline shifting tool. Differential pressure on a closed ball does not affect the actuation piston because pressure across the actuating piston is balanced while holding pressure differential across the closed ball. A check valve allows the actuation piston to be in pressure balance as the ball stays closed.
