摘要： A subsurface valve-actuator combination (13) for well production tubing is described. The valve is urged to closed position but held open by a battery-operated latch of the actuator. A receiver-relay (72) in the battery-actuator circuit maintains a switch (74) closed to permit the latch to be energized as long as the receiver-relay receives an electromagnetic signal transmitted from the earth's surface. The latch is deenergized upon interruption of the signal and/or if the battery power is insufficient to energize the same.

摘要： A downhole flow control device includes a body to be secured within a wall of a tubular, wherein the body defines a flow path therethrough, with a nozzle mounted within the flow path. A dissipation structure is positioned on a first side of the nozzle, such that fluid flowing through the body in a first direction will exit the nozzle and impinge on the dissipation structure prior to exit from the flow control device.

摘要： A downhole tool includes a valve assembly and a shock absorbing assembly. The valve assembly includes a valve spring operatively connected to a valve body. The shock absorbing assembly includes a spring operatively connected to a shock absorbing body having a fluid passage therethrough. The valve body is configured to selectively engage the shock absorbing body to create a fluid tight seal over the fluid passage in a first position, and to allow a fluid flow through the fluid passage in a second position. The repeated movement cycle of the selective engagement between the valve body and the shock absorbing body generates a pressure pulse or a varying pressure differential across the downhole tool. The repeated movement cycle is powered by a fluid flow. The tool may be selectively activated and deactivated.

摘要： A fluid flow control device comprises a housing having a fluid inlet (7) and at least one fluid outlet (8). A first fluid flow restrictor (1) serving as an inflow port to a chamber (B) in the housing, and a second fluid flow restrictor (2) serving as an outflow port from the chamber (B). The first fluid flow restrictor and the second fluid flow restrictor are configured to generate different fluid flow characteristics; and the chamber (B) comprises actuating means (5,5b-j,51) that is responsive to fluid pressure changes (”P 2 ) in the chamber. The first fluid flow restrictor (1) and the second fluid flow restrictor (2) are configured to impose its respective different fluid flow characteristics based on different fluid properties. In use, the invented fluid flow control device may be used to control fluid flow (F) through the housing, by allowing at least a portion (f) of the fluid to flow through a first fluid flow restrictor (1), into a chamber (B) and out of the chamber via a second fluid flow restrictor (2); and utilizing the pressure change (”P 2 ) in the chamber that occurs when a property of the fluid changes to operate a valve device.

摘要： A downhole pressure operated apparatus comprises a piston member mounted within a piston bore and being reconfigurable from a lock configuration to an unlock configuration in response to a pressure sequence applied within the piston bore, wherein the piston member comprises a lock profile. A lock member is arranged in a cavity which opens into the piston bore, wherein when the piston member is in its lock configuration the lock member is supported by the piston member such that the lock member partially extends into the piston bore and engages the lock profile of the piston member to restrict movement of the piston member in a first direction towards its unlock configuration. In response to a first pressure event of the pressure sequence the piston member is moveable in a second direction to desupport the lock member and permit said lock member to be wholly received into the piston bore and allow the piston member to move in the second direction towards its unlock configuration in response to a subsequent second pressure event of the pressure sequence.

摘要： A bidirectional downhole fluid flow control system is operable to control the inflow of formation fluids and the outflow of injection fluids. The system includes at least one injection flow control component 112 and at least one production flow control component 114 in parallel with the at least one injection flow control component 112. The at least one injection flow control component 112 and the at least one production flow control component 114 each have direction dependent flow resistance, such that injection fluid flow experiences a greater flow resistance through the at least one production flow control component 114 than through the at least one injection flow control component 112 and such that production fluid flow experiences a greater flow resistance through the at least one injection flow control component than through the at least one production flow control component.
