Embodiment Construction
[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0017] see Figure 1-2 , the present invention includes liquid supply reciprocating pump 1, manifold assembly 2, liquid supply main pipe 3, liquid supply manifold 4, pressurized reciprocating pump group 5. The liquid supply reciprocating pump 1 provides the drive fluid for the system, and collects it into the liquid supply main pipe 3 through the manifold assembly 2 to stabilize the pressure, and then diverts it through the liquid supply manifold 4 to each booster pump in the modular booster reciprocating pump group 5 . The driving fluid provided by the liquid supply reciprocating pump is diverted to the modular booster reciprocating pump through the liquid supply main pipe and the liquid supply manifold to realize the pumping cycle operation of high power, large displacement, long stroke and low stroke frequency. In addition to hydraulic ...

The invention discloses a high-power modular hydraulically-driven reciprocation pump system. A liquid supply reciprocation pump (1) is connected with a liquid supply main pipe (3) through a manifold component (2); the liquid supply main pipe (3) is connected with a pressurization reciprocation pump set (5) through a liquid supply manifold (4); the liquid supply reciprocation pump (1) is used for supplying driving liquid to the system; the driving liquid is gathered to the liquid supply main pipe (3) through the manifold component (2) and is shunted into all pressurization pumps in the pressurization reciprocation pump set (5) through the liquid supply manifold (4) after the pressure is stabilized. According to the high-power modular hydraulically-driven reciprocation pump system, the liquid supply reciprocation pump is used for supplying water-based or oil-based driving liquid; the driving liquid is distributed to the modular pressurization reciprocation pump set by the manifold system, so that the high-pressure pumping circulation of the working medium is achieved; the high-power modular hydraulically-driven reciprocation pump system has the characteristics of long stroke, low stoke frequency, large displacement, stable operation, environment friendliness, high efficiency and long fatigue life, is capable of flexibly configuring power and displacement according to operation requirements and can meet various operation conditions.
Description
technical field [0001] The invention belongs to the field of oil drilling equipment, in particular to a reciprocating pump. Background technique [0002] As the development of oil and gas fields, especially unconventional oil and gas resources, is becoming more and more difficult, the scale of drilling, well completion, fracturing and other construction operations is also increasing. High-power, high-pressure, high-displacement well washing, cementing, fracturing and other construction operations are more frequent, and the single well operation time is longer. The core equipment in the above operation process is the reciprocating pump that realizes the pumping circulation of mud, fracturing fluid, cement and other liquids or liquid-solid mixtures. Therefore, with the increase in scale, frequency and duration of the above-mentioned construction operations, the requirements for reciprocating pumping equipment are also getting higher and higher. Most of the current reciprocat...
