Abstract
The utility model provides an inner directional composite perforator, and relates to a bullet perforating gun. The inner directional composite perforator comprises a gun body, four gun carriers are arranged in the gun body, the gun carriers are connected through neck bearings, and the outer surface of each gun carrier is provided with a balancing weight. The inner directional composite perforator solves the strength problem of the inner directional composite perforator in a horizontal well. According to experiment testing, perforation counterpoint rate of perforating bullets of the inner directional composite perforator reaches to 100 %, flaws are not enabled to appear on the gun body, a largest height of burrs in a sleeve is 2.4mm, and various indexes all fit with relative requirements of GB / T 20488-2006 Gas Well Energy-gathered Perforation Equipment Performance Test Methods and GB / T 20489-2006 Gas Well Energy-gathered Perforation Equipment General Technical Specification.
Description
Technical field
The utility model relates to a kind of gun perforator.
Background technology
At present the horizontal well perforation technology is used widely in oil field development, employing be the conventional perforation technology.And the compound technique of perforating that beam hole, gas pressure break are integrated all is widely applied in straight well, inclined shaft, has obvious volume increase, augmented injection effect.But oriented perforating is not used widely in horizontal well perforation, chief reason is that horizontal well perforation needs orientation, especially adopt the interior orientation perforator, the body of a gun can't be opened the blind hole corresponding with perforating bullet and relief hole, and the intensity of rifle body is had certain impact.
Summary of the invention
The utility model aims to provide a kind of high-intensity interior orientation composite perforator that can use in horizontal well.
Interior orientation composite perforator described in the utility model comprises the rifle body, is provided with four firing mounts in the rifle body, link to each other by intermediate bearing between the firing mount, and the external surface of each firing mount is equipped with balancing weight.
Preferably, the rifle body is 4 meters long, and firing mount is 1 meter long.
Perhaps more preferably, the wall thickness of rifle body is 9mm.
The utility model has solved the strength problem of interior orientation composite perforator in horizontal well, through experimental test, find that interior orientation composite perforator perforating bullet perforation of the present utility model has all reached 100% to bit rate, crackle does not appear in the rifle body, the 2.4mm of sleeve pipe inner burr height maximum, indices all meet GB/T20488-2006＜＜Oil/gas Well jet perforator wood property can test method " and the relevant regulations of GB/T20489-2006 " Oil/gas Well jet perforating equipment general technical specifications ".
Description of drawings
Fig. 1 is the sectional view of firing mount among the embodiment one.
The specific embodiment
Embodiment one.
The interior orientation composite perforator, 4 meters of its rifle bodies are long, and wall thickness is 9mm.Be provided with four in the rifle body and be respectively 1 meter long firing mount 1, link to each other by intermediate bearing 3 between the firing mount 1, the external surface of each firing mount 1 has all welded balancing weight 2 in addition.Perforating bullet is horizontal in the rifle body, guarantees the horizontal perforation of perforating bullet.
