Abstract

The invention relates to a hydraulic bidirectional pumping device which comprises a prime motor, a hydraulic oil pump, a hydraulic oil tank, a control valve, a double-action hydraulic cylinder and plunger pumps. The prime motor drives the hydraulic oil pump. The hydraulic bidirectional pumping device utilizes the double-action hydraulic cylinder to drive the plunger pumps on both sides; the cylinder number is increased; stroke times are reduced; the service lives of easily damaged parts are prolonged; the coverage range of flow is effectively enlarged; suction efficiency of fracturing fluid is effectively improved; complexity of the integral structure is reduced; cost of manufacturing, maintenance and the like is reduced; the requirements on a lubricating system are lowered; the double-action hydraulic cylinder reciprocates to do work, so that working efficiency is improved.

Description

Technical field

[0001] The invention relates to the field of oil and gas exploitation, in particular to a hydraulic bidirectional pumping device applied to field operations of oil and gas wells. Background technique

[0002] Fracturing technology is currently one of the important means for developing oil and gas, especially for domestic shale gas development in China. For low-permeability oil and gas reservoirs, fracturing operations are generally required to achieve stable and increased production of oil and gas. As the main operating unit of fracturing construction, the principle of fracturing pump is to use hydraulic action to inject fracturing fluid into oil and gas wells and form high pressure, which makes the oil and gas layers form larger cracks. The main function of fracturing is to increase the seepage capacity of oil and gas and increase oil and gas production.

[0003] At present, the conventional fracturing pump is installed on the fracturing truck. During the construc...
