Abstract

The invention discloses a foaming mechanism, a high-energy gas foam fracturing device and a process. The foaming mechanism and the high-energy gas foam fracturing device are combined to form a high-energy gas foam fracturing device. The foaming mechanism is used to form foam to Foam fracturing is performed on the target layer, and the high-energy gas fracturing device continues to perform high-energy gas fracturing on the target layer to solve the problem that the existing foam fracturing process can produce wider cracks but it is difficult to form a fracture network and the high-energy gas fracturing process can The fracture network is generated but the fractures are short, and a large area of ​​fracture surface cannot be generated, and the communication between layers is poor.

Description

technical field [0001] The invention relates to a horizontal well fracturing device and a fracturing process. Background technique [0002] The advantage of foam fracturing in the existing fracturing technology is that foam fracturing has high viscosity, which is conducive to fracturing the formation and produces wider cracks. However, the cracks generated by foam fracturing mostly extend up and down. It is not large, and it is difficult to form a seam net. [0003] High-energy gas fracturing is to use a large amount of high-temperature and high-pressure gas generated by the rapid combustion of gunpowder or rocket propellant in the wellbore to extrude a radial multi-fracture system on the production layer, improve the permeability of the near-wellbore zone, and thereby increase the production and injection rate of oil and gas wells. A production increase measure for well injection. [0004] However, most of the high-energy gas fracturing fractures have poor elongation and ...
