Description
technical field [0001] The invention belongs to the technical field of water injection pumps, and in particular relates to a reciprocating plunger water injection pump. Background technique [0002] Water injection exploitation of oil is the main method of oil field exploitation at home and abroad. Water injection exploitation of oil accounts for about 1 / 3 of the total development cost. At present, there are two main types of water injection equipment at home and abroad. According to the water injection volume, 70% of the water injection volume is injected by a high-pressure centrifugal pump, and its pressure is below 16 MPa; 30% of the water injection volume is injected by a mechanical plunger pump, and its pressure is 16 MPa. ~45MPa. For the development of low-permeability reservoirs, high-pressure mechanical plunger pumps must be used. With the continuous reduction of rich ore and the continuous increase of low-permeability reservoir development, the demand for mechanic...
