Problems solved by technology
[0002] After the perforation operation, the oil well cannot perform oil production immediately, or cannot obtain satisfactory production, so operations such as acid fracturing must be carried out, but the existing perforation tools and acid fracturing tools are separated, and the operation steps are cumbersome. Moreover, frequent operations in oil wells where the perforation cracks have not been fixed may easily cause crack closure. Only when perforation is done at the same time, and then the perforation is acidified, and the perforation is solidified, and the acidification is to keep the oil well for a long time. High production; however, the existing perforating guns have a single function and can only be used for perforation, and have no other functions

Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0028] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.
[0029] Such as Figure 1-5 As shown, the present invention provides a high-energy gas fracturing stimulation injection device for oil wells, including:
[0030] The main rod 1 is a hollow cylinder and is vertically arranged. The outer wall of the lower part of the main rod 1 is provided with a perforation 4 and a liquid spray hole 6 spirally wound around the outer wall of the main rod 1. The perforation 4 The liquid spray holes 6 are alternately arranged vertically, the centers of the liquid spray holes 6 and the perforations 4 are on the radial line of the same main rod 1, and ...

The invention discloses a high-energy gas fracturing stimulation and stimulated injection device for an oil well. The high-energy gas fracturing stimulation and stimulated injection device comprises amain rod, a perforation hole, a liquid spraying hole, an initiator, a liquid feeding pipe, a cylindrical barrel, a first compression spring, a second compression spring, a sliding rod, a fixed rod, afirst anti-corrosion sleeve, a second anti-corrosion sleeve, an outer sleeve, a third compression spring, a partition plate, an initiation hole, screen holes, a ground grabbing ring, a rigid sleeve and a V-shaped elastic fastener. The perforation and acidizing fracturing operations can be completed simultaneously, the problem can also be effectively prevented that a perforating gun rebounds due to explosion impact force increase in the perforating process, accidents are avoided, and the safety and efficiency of oil well operations are guaranteed.
Description
technical field [0001] The invention relates to the field of oil well equipment. More specifically, the invention relates to a high-energy gas fracturing stimulation injection device for oil wells. Background technique [0002] After the perforation operation, the oil well cannot perform oil production immediately, or cannot obtain satisfactory production, so operations such as acid fracturing must be carried out, but the existing perforation tools and acid fracturing tools are separated, and the operation steps are cumbersome. And frequent operations in oil wells where the perforation cracks have not been fixed may easily cause crack closure. Only when perforation is done at the same time, and then the perforation is acidified, and the perforation is solidified, and the acidification is to keep the oil well for a long time. High yield; but the existing perforating gun has a single function and can only be used for perforation, and has no other effects. Contents of the in...
