Abstract

The invention discloses a cavitation reservoir transformation test method. The cavitation reservoir transformation test method comprises the steps that a simulation shaft is arranged on a rock sample, and the rock sample is installed on a rack; a cavitator is installed at one end of a connecting pipe, the cavitator is installed in the simulation shaft through the connecting pipe, and the connecting pipe is clamped and fixed through the rack; a detection unit is installed on the rock sample; a high-pressure pump set is connected to one end, far away from the cavitator, of the connecting pipe, and the rock sample and the rack are installed in a test pool; and the high-pressure pump set is started and data measured by the detection unit are recorded. The cavitation effect of liquid is formed through the cavitator extending into the simulation shaft of the rock sample, the pressure and vibration of fluid in the simulation shaft and the transmission rule of vibration shock waves in the rock sample during cavitation reservoir transformation are analyzed by collecting vibration and fluid pressure data in the cavitation test, and the working mechanism of the cavitation reservoir transformation technology is disclosed.

Description

technical field [0001] The invention relates to the technical field of oil and gas exploitation, in particular to a cavitation reservoir reconstruction testing method. Background technique [0002] Unconventional oil and gas fields are currently a hot spot in oil and gas development, and reservoir stimulation is one of the key technologies to realize the development of unconventional oil and gas fields. However, traditional reservoir stimulation technologies usually have serious pollution, high energy consumption, and easy to aggravate reservoir heterogeneity. sexual shortcomings. In order to overcome the shortcomings of traditional reservoir stimulation technology and realize efficient and green oil and gas extraction, in recent years, the engineering community has proposed the technical concept of using cavitation technology to realize reservoir stimulation. [0003] Cavitation is the process of the formation, development and collapse of vapor or gas cavities (cavitations...
