Abstract

The utility model relates to an oil-gas well high-energy gas annular slotted fracturing bullet, of which the pressure and action time can be adjusted; wherein, a plurality of annular grooves (2) is opened on a cylindrical compression fracture (1). The fracturing bullet performs progressive burning and can improve the burning pressure of the explosive.

Description

The oil gas well high-energy gas circular groove type Pressure breaking bullet of adjustable pressure and action time
(1) technical field:
After the utility model belonged to perforating oil gas well, the high pressure that utilizes gunpowder to produce carried out the adjustable pressure of gas fracturing and the oil gas well high-energy gas circular groove type Pressure breaking bullet of action time to the stratum.
(2) background technology:
At present, the high energy gas fracture bomb that adopt in the oil field, the solid gunpowder of employing single structure, it is to ignite by the igniting powder column, and surge pressure is lower, and powder combustion time and pressure are non-adjustable, do not reach geological effect preferably.
(3) utility model content:
Technical problem to be solved in the utility model is at the problem of depositing in the background technology, and the oil gas well high-energy gas circular groove type Pressure breaking bullet of a kind of adjustable pressure and action time is provided.
The invention for solving the technical problem can reach by following technical solution: have a plurality of ring grooves on the cylindricality pressure break.
The utility model is compared with background technology has following beneficial effect: gunpowder is an ignite gunpowder and regulate surge pressure of the energy that utilizes detonating fuse blast to produce, regulates powder combustion time by fluting, boundling and solid gunpowder various combination.
(4) description of drawings:
1 Pressure breaking bullet master of accompanying drawing looks complete section figure;
(5) specific embodiment:
Below in conjunction with the drawings and specific embodiments will the utility model is described in further detail:
By shown in Figure 1, on cylindricality pressure break 1, have a plurality of ring grooves 2.

Claims (1)

  1. A kind of oil gas well high-energy gas circular groove type Pressure breaking bullet that relates to adjustable pressure and action time is to constitute on Pressure breaking bullet, it is characterized in that: have a plurality of ring grooves (2) on cylindricality pressure break (1).
