摘要： The engine shut-off valve system includes a housing, a gate member, a rotating lever, a locking piston assembly, and a closing piston assembly. The system is installed in fluid connection with a flow line so that air flow passes through a passageway in the housing with the gate member in the locked configuration. The air flow through the passageway stops with the gate member in the closed configuration. The gate member has an asymmetry so that the forces of the spring of the closing piston assembly and the spring of the locking piston assembly are cooperative to actuate between the closed configuration and the locked configuration, while wearing on the gate member differently so as to extend the working life of the valve system. The closing piston assembly and the locking piston assembly are separately accessible for maintenance.

摘要： An artificial lift system for use with a subterranean well can include a cylinder having a piston reciprocably disposed therein, the piston having opposing sides, each of the opposing sides being selectively communicable with a hydraulic pressure source and a hydraulic reservoir, and the piston having another side in communication with a gas pressure source, and the gas pressure source including a gas compressor connected between gas containers. A method of controlling an artificial lift system can include connecting a cylinder to a hydraulic pressure source and to a gas pressure source, operating a gas compressor of the gas pressure source, thereby increasing gas pressure applied to the cylinder from the gas pressure source, and displacing a piston, thereby operating a downhole pump.

摘要： An artificial lift system for use with a subterranean well can include a cylinder having a piston reciprocably disposed therein, the piston having opposing sides, one side being selectively communicable with at least one accumulator, and the other side having two areas, each of the areas being selectively communicable with a hydraulic pressure source and a hydraulic reservoir, and a gas pressure source connected to the accumulator, the gas pressure source including a gas compressor connected between at least one gas container and the accumulator. A method of controlling an artificial lift system can include connecting a cylinder to a hydraulic pressure source and to at least one accumulator, the accumulator being connected to a gas pressure source, and operating a gas compressor of the gas pressure source, thereby increasing hydraulic pressure applied to the cylinder from the accumulator.
