Abstract
The invention discloses a fracture bomb, which comprises an explosion proof device (1), a powder accommodation shell (2) and main powder(4); the main powder (4) is arranged in the powder accommodation shell (2); and the explosion proof device (1) is used for blocking direction action of impact waves or air on the fracture bomb, so the time of igniting the main powder (4) is prolonged, the impact waves pass through the explosion proof device and is attenuated to a lower peak pressure; and the peak pressure generated by a perforating bullet is prevented from being overlapped with the peak pressure generated by the fracture bomb, so time interval between the two peaks is prolonged, and the secondary booster effect of the built-in booster fracture bomb on stratum is greatly improved.
Description
Technical field
The present invention relates to Pressure breaking bullet, particularly a kind of built-in type Pressure breaking bullet in petroleum perforation, gas fracturing with buffering delay function.
Background technology
Domestic High-Energy Gas Fracturing Technology is through the research and extension of recent two decades, developed into one and has been mature on the whole, and in each oil field extensive use and obtained good economic benefit, transforms production-increasing technique to the oil-gas Layer of comprehensive pressure break development.High enegry gas fracturing and perforation complex technique are the new technologies of the increase oil and gas production that combines with high enegry gas fracturing of a perforation.Its design principle is: filling insensitiveness propellant powder group in the perforation firing mount, and having in the body of a gun that perforating bullet and firing mount be encased in perforating bullet.Adopt oil pipe remove technology with instrument down to oil gas well target zone position. caber ignites that igniter cap, igniter cap are ignited detonating fuse, the detonating fuse ignition is connected the perforating bullet on the detonating fuse.Perforating bullet penetrates the body of a gun and target zone sleeve pipe, form preforation tunnel at the oil-gas Layer position, propellant powder in the body of a gun of delayed combustion, the high temperature and high pressure gas that burning produces washes away by preforation tunnel, strengthen intensification perforation hole depth and can reach 1-2m, the gases at high pressure of assembling form many cracks in the preforation tunnel forward position rapidly, and the crack scope can reach 1-2m, the mediation radius of perforation and single high enegry gas fracturing is all big separately, and it is more effective to increase oil and gas production.
Pressure breaking bullet in the conventional composite perforator just simply is installed between the perforating bullet, and the direct impact of shock wave that Pressure breaking bullet is produced by perforating bullet is lighted, and there is following defective in the Pressure breaking bullet of this kind assembling mode: explosive payload is few; Shorter action time to the stratum; The superimposed interior surge pressure of rifle that causes of the pressure that pressure that Pressure breaking bullet produces and perforating bullet produce is higher, has increased the hidden danger of fried rifle.
In order to hinder or slow down the impact to Pressure breaking bullet of shock wave that perforating bullet produces, the surge pressure that the control composite perforator produces has designed a kind of high-energy built-in type synergy Pressure breaking bullet that cushions time-lag action that has.
Summary of the invention
In view of this, the present invention proposes a kind of built-in type synergy Pressure breaking bullet, has the buffering time-lag action, guarantee that the surge pressure of perforating bullet generation and the surge pressure that the synergy Pressure breaking bullet produces do not superpose, thereby the prolongation Pressure breaking bullet is to the action time on stratum.
A kind of Pressure breaking bullet comprises explosion isolation device, and charge shell, main charge, main charge are installed in the charge shell, and explosion isolation device obstruction shock wave or gas have prolonged the time that main charge is lighted to the direct effect of Pressure breaking bullet.
Described explosion isolation device comprises dividing plate, bumper and absorbing shock assembly, flame proof body; The upper and lower end face of described Pressure breaking bullet all is provided with the explosion isolation device sealing; The shape of described explosion isolation device can be for cylindrical.
Described bumper and absorbing shock assembly can be a kind of in high strength aramid fiber base cloth and blowing agent filling molding, polyurethane foams, visco-elastic damping material, polyurethane foams and the volute spring cast molding material based on natural rubber.
There is clad to separate between charge shell and the main charge; Clad can be for rubber or based on the visco-elastic damping material of natural rubber; The shape of clad can be a cylindrical shape.
Charge shell can be processed into by seamless steel pipe, nylon or phenolic aldehyde cotton layer pressure pipe;
Be processed into if the charge shell heavy wall is a seamless steel pipe, then charge shell is provided with one or more ring grooves outward, makes this charge shell have the shock resistance explosion prevention function.
The propellant powder of main charge can for: single-base gun propellant is 5/7,9/7,11/7, and double-base propellant is two virtues-2, two virtue-3, and novel propellant powder is nitroguanidine propellant, Ding Fang-3 propellant powder, heat resistant propellant; The shape of described propellant powder can be granular medicine or tubulose grain medicine;
Double base propellant is two fragrant magnesium-1, Ledate-2, two cobalt-2, modified double base propellant; Described propellant shape can be tubular powder, fluting tubular powder.
Described Pressure breaking bullet uses in perforator or composite perforator.
Because the buffering of built-in type synergy Pressure breaking bullet time-delay design feature, the shock wave that makes perforating bullet produce can decay to lower surge pressure through explosion isolation device, charge shell, clad, guarantee that the surge pressure of perforating bullet generation and the surge pressure that Pressure breaking bullet produces do not superpose, thereby prolonged the blanking time of two peak values, improved the secondary synergistic effect usefulness of built-in type synergy Pressure breaking bullet greatly the stratum.
