Abstract

The invention relates to a pulser for fracturing. The pulser includes a constant-speed constant-pressure pump, an energy accumulator, a servo motor, an automatic valve and a PLC control center, wherein the constant-speed constant-pressure pump communicates with a water inlet of the automatic valve through a liquid inlet pipe, a water outlet of the automatic valve communicates with a fracturing well through a liquid outlet pipe, the automatic valve is connected with the servo motor, the servo motor drives the automatic valve to open and close and is connected with the PLC control center, the PLC control center controls the rotate speed of the servo motor, the energy accumulator is arranged at the front end of the water inlet of the automatic valve, and the energy accumulator communicates with the liquid inlet pipe through a first valve. According to the pulser for fracturing, the PLC control center controls the rotate speed of the servo motor, thus opening frequency of a ball valve is controlled, fracturing liquid enters the fracturing well and forms certain pulse, thus pulse fracturing of rock is achieved, usage amount of the fracturing liquid is largely lowered, and the fracturingefficiency is high.

Description

technical field [0001] The invention relates to the field of fracturing devices, in particular to a pulse generator for fracturing. Background technique [0002] The existing rock fracturing technology adopts the method of hydraulic fracturing, which requires a large amount of fracturing fluid, resulting in a lot of waste of resources, and the fracturing efficiency of hydraulic fracturing is relatively low, which leads to the extension of the construction period and affects the follow-up process . Contents of the invention [0003] The object of the present invention is to provide a pulse generator for fracturing to solve the problems of low hydraulic fracturing efficiency and waste of resources in the prior art. [0004] The invention provides a pulse generator for fracturing, including a constant speed and constant pressure pump, an accumulator, a servo motor, an automatic valve and a PLC control center. The constant speed and constant pressure pump is connected to the ...
