摘要： According to the present invention, there is provided a device for guiding a tool on a string within a blow out prevention ("BOP") stack. In one embodiment, the device includes a top collar connected to a bottom collar by a shroud having a plurality of flexible members which bow outwardly from the collars, wherein the shroud covers a portion of the tool. An energy absorbing bumper is provided above the top collar to absorb structural impact caused by a blow out or other inadvertant pressure in a downhole application.

摘要： A gate valve includes a pressure relief port located on the gate valve. When the gate is positioned such that the port communicates with one of the two flow passages and the valve body interior, uni-directional flow is permitted from the other of the flow passages. Flow is blocked bi-directionally when the port is positioned out of communication with the flow passage.

摘要： A casing seal for use with a source of high pressure fluids with apparatus for preventing shredding of the seal with variations in fluid pressure. A T-shaped annular metal ring provides a multiplication of fluid pressure so pressure exerted on an elastomeric sealing ring is greater than the fluid pressure. This multiplication prevents gases from entering the elastomer and prevents shredding of the elastomer when pressure is released. The multiplication of pressure also forces the elastomer firmly against a casing and a casing head to provide a fluid-tight seal.
摘要翻译：一种用于与高压流体源一起使用的套管密封件，具有用于防止密封件随流体压力变化而破碎的装置。 T形环形金属环提供流体压力的乘积，因此施加在弹性体密封环上的压力大于流体压力。这种倍增防止气体进入弹性体，并防止压力释放时弹性体的破碎。压力的增加也迫使弹性体牢固地抵靠套管和套管头以提供流体密封。
