Abstract
The utility model relates to a non-gun body pressure-resistance perforating bullet used in the exploitation work of oil wells, which is composed of a bullet case, a medicine-shaped hood, a bullet cover and the high explosive, wherein the center of the head part of the bullet case is provided with closed explosion transmitting holes, the hole openings of the inner ends of which are arranged in an inner cavity of the bullet case. The explosion transmitting outer end of the explosion transmitting hole is isolated and closed by the bullet case, and the booster and the high explosive are arranged between the medicine-shaped hood and the inner wall of the bullet case. A medicine filling opening of the bullet case is sealed by the bullet cover, and the inner parts of the explosion transmitting holes near the bullet case are provided with the explosion expanding tubes of the booster. The explosion expanding tube forms a shape of box body by a metal tube casing, and a medicine filling tube nozzle of the metal tube casing is sealed by a metal sealing piece. Because the explosion expanding tube filled with the booster is additionally arranged in the explosion transmitting hole, the utility model enhances the detonating force, has the advantages of high safety and reliability, avoids the extinguishing of the perforating bullet, simultaneously adopts the reasonable thickness of isolating the bullet case, efficiently ensures the reliable detonating of the perforating bullet, causes the emissivity of the pressure-resistance perforating bullet to achieve 99.99 percents and can resist the pressure of 70MPa.
Description
Technical field
The utility model is the withstand voltage perforating bullet of the no body of a gun that uses in a kind of oil mining operation.
Background technology
In petroleum industry, the oil well perforation operation is an important operation, be that high lined-cavity charge is installed in the perforating gun, treat behind the target zone of down-hole, to ignite under it, after high lined-cavity charge after the ignition penetrates perforating gun, further penetrate sleeve pipe and the cement layer of wearing the borehole wall, the stratum is communicated with oil well, reach hydrocarbon stratum and can flow into the oil well purpose smoothly.The perforating bullet of common propagation of explosion is to be made of steel shell case, booster explosive, main charge, drug-shaped cover, drug-shaped cover is arranged in the shell case, be provided with booster explosive and main charge between drug-shaped cover and the shell case inwall, this kind perforating bullet is installed in the perforating gun of sealing, directly being close to booster explosive by the detonating fuse of perforating gun serial connection detonates, after the perforating bullet main charge is ignited, the shell case fragmentation, drug-shaped cover pools high-energy fluid vertically and penetrates perforating gun, sleeve pipe and cement layer under high temperature, high pressure and high-energy effect, oil gas flows into oil well from the stratum.Another kind is the withstand voltage perforating bullet of the no body of a gun, its main quick-fried structure and common piercing bullet are similar, but withstand voltage perforating bullet is installed on the perforator of open type, detonating of withstand voltage perforating bullet is to lean on the detonation wave that produces behind the fuse arming test experiment initiation, through booster explosive and the main charge in the perforating bullet that detonates after metal partion (metp) (the propagation of explosion hole of shell case head the is a closed) decay, so, because shell case (metal division board) is arranged between booster explosive that is provided with in the propagation of explosion hole of perforating bullet bullet position and the detonating fuse isolates, just caused withstand voltage perforating bullet when initiation process, propagation of explosion is undesired, the perforating bullet emissivity is low, the phenomenon of failing to explode often occurs, cause potential safety hazard also for easily simultaneously the oil well mining operations.
The utility model content
The purpose of this utility model is to provide a kind of efficient, reliable, safe withstand voltage perforating bullet of the no body of a gun into solving the problem that prior art exists, and can stop the problem that perforating bullet can not be ignited fully.
The utility model is achieved in that the withstand voltage perforating bullet of a kind of no body of a gun is made of shell case, drug-shaped cover, bullet lid, booster explosive, high explosive, the head central authorities of shell case are provided with the propagation of explosion hole of sealing, the inner aperture in propagation of explosion hole is positioned at the inner chamber of shell case, the propagation of explosion outer end in propagation of explosion hole isolates sealing by shell case, between drug-shaped cover and the shell case inwall booster explosive and high explosive are set, the shell case medicine containing opening is provided with the propagation squib that booster explosive is housed through the sealing of bullet lid near in the propagation of explosion hole of shell case.
Described propagation squib can constitute the box body shape by Can, and the powder charge mouth of pipe of Can passes through a metallic seal sheet with the powder charge ferrule.
Described Can be aluminium casing, and the metallic seal sheet is an aluminum alloy sheet, and the powder charge mouth of pipe of Can is towards high explosive.
The diameter in described propagation of explosion hole can be Φ 3mm～Φ 8mm.
