Abstract

The invention discloses a hydraulic pulse generator and a hydraulic pulse fracturing device. The hydraulic pulse generator can convert high-pressure liquid into low-frequency pulse high-pressure liquid through the elastic potential energy of a spring so as to enhance a pulse pressure and form a high impact force. The hydraulic pulse generator is specifically applied to the hydraulic pulse fracturing device. The problem that when an existing hydraulic pulse fracturing device conducts hydraulic fracturing, fracturing liquid cannot enter a stratum with the high impact force, and consequently efficient fracture forming cannot be achieved is solved.

Description

technical field [0001] The invention relates to a hydraulic pulse generating device and a hydraulic pulse fracturing device. Background technique [0002] In the past ten years, the problem of low-permeability reservoir stimulation has become more and more serious. Hydraulic fracturing technology is the most common solution. A large amount of friction consumes part of the energy, so that the fracturing fluid cannot enter the formation with a high impact force and cannot effectively create fractures. [0003] At present, hydraulic pulse fracturing technology is a new type of technology, which can effectively solve the loss of energy, create high-impact pulse waves, and form a "water hammer effect", so that high-pressure liquid can quickly enter the formation and form a complex fracture network pattern. The technology has broad development space and application prospects. [0004] Existing hydraulic pulse fracturing devices are few and have defects. For example, Chinese pate...
