ACCUMULATOR OVER HYDRAULIC PUMP DOUBLE-ACTNG CYLINDER FOR ARTIFICAL LIFT OPERATIONS |
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 a hydraulic pressure source and a hydraulic reservoir, and the other side being selectively communicable with the hydraulic pressure source and at least one accumulator, and the accumulator being selectively communicable with an input side of a pump of the hydraulic pressure source. A method of controlling an artificial lift system can include connecting a cylinder to a hydraulic pressure source including a hydraulic pump, the pump being connected between the cylinder and 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 pump from the accumulator. |
