    摘要: A self-cleaning temperature sensor comprises: a bellows coupled to a support structure; a pneumatic or hydraulic cylinder; a sensor configured to measure a temperature of a fluid and extending from the pneumatic or hydraulic cylinder, wherein the sensor comprises an exposure end configured to contact the fluid during sensing by the sensor; sensor wires connected with the sensor and extending to a control system; and a self-cleaning system comprising: a hood having walls extending radially outward a distance along a central axis wherein the hood defines a first volume; and a cleaning brush integrated with or adjacent the bottom of the support structure. In a retracted configuration, the exposure end of the sensor is positioned at a retracted position a distance from cleaning brush, and, in an extended configuration, the exposure end of the sensor extends a distance along the central axis away from the retracted position.

    摘要: A method for tuning a distributed acoustic sensing (DAS) system. The method may include determining a signal strength from a first Raman Pump in the DAS system, sweeping a laser pulse output from a transmitter; wherein the sweeping is an incremental increase of a power of the laser pulse output from a minimum pulse power to a maximum pulse power, and measuring a first signal-to-noise-ratio (SNR) for each of the incremental increase of the power of the laser pulse output. The method may further comprise selecting a maximum SNR from the first SNR for each of the incremental increase of the power of the laser pulse output and configuring the first Raman Pump and the laser pulse output based at least in part on the maximum SNR.

    摘要: Disclosed herein are systems and methods including an electromechanical brake used downhole to impart dynamic or static braking capabilities while absorbing or otherwise reducing shock loads. The electromechanical brake may be used for a downhole electromechanical linear actuator to control a valve for the production of subterranean fluid. In some examples, it may be desirable for an electromechanical linear actuator to maintain a retracted position during certain safety and/or maintenance operations. The electromechanical brake includes a brake housing, a first armature rotatably disposed in the brake housing, a second armature rotatably disposed in the brake housing for rotation by a motor, an electrical coil energizable to urge the second armature into axial engagement with the first armature, and a rotational spring for biasing the first armature to a neutral rotational position relative to the brake housing while allowing a limited rotation of the first armature relative to the brake housing.

    摘要: A travel joint may accommodate relative movement between an upper and lower completion for communication of well fluids and control signals, while protecting the control lines used for signal control In one example, the travel joint has an upper tubular member telescopically coupled to the lower tubular member to collectively define a flow path for well fluids through the travel joint. A plurality of telescoping control line conduits are secured about a travel joint periphery, each including an outer tube telescopically coupled to an inner tube to accommodate relative movement between the upper and lower tubular members. A control line routed through each telescoping control line conduit. A dynamic or expanding/hardening seal interface may be provided in the control line conduit to protect the control lines routed therethrough.
