Jet gun

Abstract

The invention provides a jet gun used for fracturing operation. The jet gun comprises a body and a jet nozzle, wherein the body is provided with a cavity, the jet nozzle is formed in the body and provided with a jet hole, the jet hole is used for communicating the cavity with the outside, and a jet included angle A is formed between the axis of the jet hole and the radial plane of the body. The jet gun solves the problems of low sand jet perforation efficiency and short service life due to imperfect perforation of a jet gun in the prior art.

Description

technical field [0001] The invention relates to the technical field of oil fracturing, in particular to a spray gun. Background technique [0002] In the field of fracturing technology, hydraulic jet fracturing technology has been widely used due to its advantages of accurate fracture location, no need for mechanical isolation and no pollution to the formation. [0003] With the continuous development of oilfields, the depth of wells and the scale of reconstruction are increasing, and higher technical requirements are put forward for fracturing tools. Spray gun is a commonly used fracturing tool that relies on hydraulic sand-carrying perforation. [0004] However, when the traditional spray gun is in use, the problem of low efficiency of sandblasting and perforating operation will occur due to the imperfect perforation. After the tube is on, it will splash back and cause erosion of the spray gun, which seriously affects the service life of the spray gun. Contents of the i...
