Abstract: A well choke, and an actuation mechanism for the well choke are described. The actuation mechanism includes a linearly translating drive mechanism which is coupled to a valve member drive assembly through a fluid coupling which facilitates a change in the overall length of the actuation mechanism. Fluid in the fluid coupling can be released in response to fluid pressure exerted on the valve member when it is proximate a valve seat of the choke, to achieve this change in length. In some embodiments, the fluid coupling will provide a retained fluid column and the valve member drive assembly will include a piston with in the fluid coupling which is movable from a fully extended to a compressed, by the release of fluid from the coupling in response to pressure in the chamber reaching a threshold level.

Abstract translation: 描述了井膛和井扼流器的致动机构。 致动机构包括线性平移驱动机构，其通过流体联接件联接到阀构件驱动组件，该流体联接器有助于致动机构的总长度的变化。 流体联接器中的流体可以响应于当阀构件靠近扼流圈的阀座时施加在阀构件上的流体压力而释放，以实现长度的这种变化。 在一些实施例中，流体联接器将提供保持的流体柱，并且阀构件驱动组件将包括具有在流体联接器中的活塞，该活塞可通过从耦合器释放流体而从完全延伸到压缩的活塞，以响应于 室内的压力达到阈值水平。

Abstract: A valve stem arrangement for use in an adjustable choke, the valve stem being configured to prevent damage to components of the adjustable choke during downstream overpressure conditions. The valve stem generally connects a valve gate to an actuator for moving the valve gate within the choke. A set of shear screws couple components of the valve stem together. During overpressure conditions, the shear screws shear, permitting retraction of the valve gate towards an open position, thereby relieving loads on various choke components.

Abstract: A seal bore protector for protecting a seal bore of a rotating control device (RCD) is provided. The seal bore protector includes a cylindrical body, a throughbore extending through the cylindrical body, and a sealing element disposed around an external surface of the cylindrical body. The sealing element includes a first sealing ring, a second sealing ring, and a sealed area between the first sealing ring and the second sealing ring. The sealed area is fluidly coupled with a port when the seal bore protector is installed in the rotating control device.

Abstract: A rotating control device (RCD) sensor assembly is provided. The rotating control device sensor assembly includes an emitter disposed on a rotational component of a rotating control device, wherein the emitter emanates a detectable signal field, a cap coupled to the rotational component to form a volume between the cap and the rotational component, wherein the emitter is enclosed within the volume, and wherein the cap is made of a transmissive material, and a sensor that detects the signal field through the cap as the emitter passes within a proximity of the sensor.
