For achieving the above object, the technical solution adopted in the utility model is:
A kind of reusable oil gas well synergistic perforator, its special character is: comprise perforating gun rifle body, in the described perforating gun rifle body firing mount is housed, firing mount is provided with the bullet trustship that is used to place perforating bullet, have the stepped hole corresponding with playing trustship on the rifle body, rifle body upper end is an ignition and detonation mechanism.
Above-mentioned firing mount can be the nonmetal energy firing mount that contains, and is evenly equipped with the through holes of 90 degree on it, plays trustship and fixedlys connected with firing mount by through hole.
Above-mentioned perforating bullet is with the guiding supporting positive cover outward.
The contact surface of above-mentioned guiding supporting positive cover and stepped hole inside diameter surface can be oval, and in the minor axis center one open gap is arranged, and open gap one side is a taper surface.
Can be provided with detent mechanism in the firing mount two ends above-mentioned nonmetal containing.
Above-mentioned ignition and detonation mechanism comprises the top connection of being located at rifle body upper end, and top connection is connected with reducer union, is fixed with high pressure skewer pin in the reducer union, and high pressure skewer pin is connected with detonator, and detonator is connected with detonating fuse, and detonating fuse also passes the nonmetal energy firing mount that contains.
Be stamped the seal cover board of two ends perk on the stepped hole of above-mentioned rifle body.
Above-mentioned rifle body lower end can be a plug.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
1, the utility model perforating effect is good, and can reuse, and has reduced cost effectively;
2, the utility model is easy to use, is the regeneration product of existing perforating system, has vast market prospect.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
