摘要： An electrically operated catcher mechanism that is part of a lubricator and catcher unit used in conjunction with a bypass plunger in an oil or gas well include an electrically operated mechanism to move between the catch and release positions. The electrically operated catcher mechanism includes a cam rotated by a motor which causes the device to move between catch and release positions.

摘要： A disclosed control system for a gas assisted plunger lift (GAPL) system includes a sensor and a processor circuit. The sensor is configured to measure a plunger speed and/or velocity and the processor circuit is configured to control various parameters of the GAPL based on the measured plunger speed and/or velocity. The processor circuit may be configured to adjust a gas injection rate parameter based on the measured plunger speed and/or velocity, and/or may adjust one or more parameters including: a close time, an afterflow time, a flow rate, a load factor, a tubing pressure, a casing pressure, and a tubing/casing differential pressure. The controller may be further configured to adjust all parameters simultaneously or may sequentially adjust a first sub-set of parameters and then adjust a second sub-set of parameters. The first sub-set may include a gas injection flow rate and the second sub-set may include after-flow and close time parameters.

摘要： A bypass plunger combines a unitary or one-piece hollow body-and-valve cage, retains a dart valve within the valve cage portion of the hollow body using a threaded retaining nut secured by crimple detents. A series of helical grooves surround the central portion of the outer surface of the hollow body of the plunger to control spin during descent. A canted-coil-spring disposed within the retaining nut functions as a clutch. The valve cage includes ports that may be configured to control flow through the plunger during ascent. Other embodiments include clutch assemblies using canted-coil springs with split bobbins, and valve stems surfaced to achieve specific functions. Combinations of these features provide enhanced performance, durability and reliability at reduced manufacturing cost, due primarily to the simplicity of its design.

摘要： A bypass plunger includes a plunger body that includes a head portion located at one end of the plunger body and a tail portion located at an opposite end of the plunger body. The head portion includes at least one flow port, and the tail portion includes at least one passageway. A valve component is disposed within an internal bore of the plunger body and is moveable between an open position and a closed position. At least one plug is located within a respective one of the flow ports and/or a respective one of the passageways, and is configured to reduce or prevent flow through the respective flow port or the respective passageway.

摘要： A bumper spring assembly having a one piece mandrel including an integral head piece is further configured with a cage assembly retained on the mandrel with a cage nut locked to the mandrel to obviate the need for pins, set screws, and the like, to provide a more robust assembly. In two embodiments the cage nut is locked to the mandrel in a swaging operation. Improved flow of fluids through and around the bumper spring assembly are also provided

摘要： A bypass plunger includes a unibody, or one-piece hollow body and valve cage, retains a dart valve within the valve cage portion using a threaded retaining nut secured by crimple detents, and includes sealable flow parts. A series of helical grooves surround the central portion of the outer surface of the hollow body of the plunger to control spin during descent. A canted-coil-spring disposed within the retaining nut functions as a clutch. The valve cage includes ports that may be configured to control flow through the plunger during descent. Other embodiments include clutch assemblies using canted-coil springs with split bobbins, and surfaced valve stems surfaced.

摘要： A dome cap and tail plug assembly for a flow control device include a dome that attaches to an upper end of a body of the flow control device and a tail plug that screws into a top of the dome cap. A seal is provided between the dome cap and the tail plug. The seal can be formed by one or more sealing elements, such as O-rings, positioned between the dome cap and the tail plug. The seal can also be provided by engagement between a shoulder on the tail plug bearing against an end face of the dome cap. Also, threads used to couple the tail plug to the dome cap could be conical threads, which also help to provide a seal between the dome cap and the tail plug.
