Hydraulic jet fracturing technology of hydraulic jet as the main method, can produce cracks along the section at a specified location, in the process of development and expansion of the cracks running through high pressure hydraulic jet fracturing fluid, all the work string into the pump and through the injection tool acting on the jet formation, and extended perforation channel and cracks. Produce. The fluid pumped from the annulus is mainly used to maintain the annulus pressure, and most of the annular fluid is used to supplement the leakage of the liquid, and a few of them enter the cracks. Water jet assisted fracturing process and conventional fracturing are similar, it will lead fluid, fracturing fluid and washing fluid from the injection of fracturing tubing. To some extent, hydraulic jet assisted fracturing is a technique that combines hydraulic jet perforation with conventional hydraulic fracturing.
