Abstract
The utility model discloses a built-in secondary synergy compound gun perforator which is formed by being internally provided with a gun carrier which is provided with a perforation charge, a high-speed loading pressure cracking charge, an obstruction layer and an intermediate-speed pressure cracking charge in sequence and orderly connected by an explosive fuse. The built-in secondary synergy compound gun perforator is characterized in that a separator is arranged between the intermediate-speed pressure cracking charge and the perforation charge so as to relieve the impact of detonation waves of the perforation charge upon the intermediate-speed pressure cracking charge, thereby preventing the intermediate-speed pressure cracking charge from being quickly lighted; the intermediate-speed pressure cracking charge is lighted after the relief of the impact of detonation waves of the perforation charge by the separator so as to achieve normal combustion under high temperature and high pressure, thereby generating secondary pressure peak and enabling the secondary pressure peak to last for certain time; and the time for the secondary pressure peak lasting is determined by changing the material and the structure of the separator and the design of the intermediate-speed pressure cracking charge, thereby achieving the aim of production and injection increase.
Description
Affiliated technical field
The utility model relates to a kind of perforator, and particularly a kind of secondary synergy composite perforator that is used for oil (gas) well belongs to oil development and exploitation equipment field.
Background technology
Usually composite perforator can be divided into integral type, hanging, jacket-type etc. down, and what present domestic use was more is the integral type composite perforator.The integral type composite perforator is to install 1 high speed additional to load Pressure breaking bullet between adjacent 2 launch hole bullets, the detonation wave that produces after perforating bullet detonates can cause the detonation that loads Pressure breaking bullet at a high speed, the gases at high pressure that produce just can reach higher surge pressure at short notice, the duct that gases at high pressure are launched out by perforation, the stratum is carried out once loading at a high speed, by high speed loading effect the permeability that pressure break is improved oil reservoir is carried out on the stratum, reduce oil flow resistance, realize increasing yield and injection.Dress loads the quantity decision of the quantity of Pressure breaking bullet by perforating bullet at a high speed in this perforator, filling quantity is restricted, and the speed of action of this Pressure breaking bullet is fast, instantaneous pressure is high, the duration is short, thus limited to the action time on stratum, can not reach the effect of desirable increasing yield and injection.
Summary of the invention
For overcoming above-mentioned defective, the utility model provides a kind of built-in type secondary synergy composite perforator, it comprises rifle head, composite perforation gun, perforating bullet, high speed Pressure breaking bullet, gun breech, detonating fuse, it is characterized in that: middling speed is housed between perforating bullet loads Pressure breaking bullet, middling speed loads between Pressure breaking bullet and the perforating bullet barrier layer.The utility model is to install the middling speed Pressure breaking bullet in the integral type composite perforator additional.After the high speed of this composite perforator loads the Pressure breaking bullet detonation, the high temperature and high pressure gas that produces is realized earlier loading at a high speed to reservoir, reservoir moment reaches higher pressure peak, middling speed Pressure breaking bullet again ignites after produced simultaneously detonation wave is decayed through barrier layer, make it to be in fired state, the gases at high pressure that produce can be kept pressure peak and continue the regular hour, and by the eyelet of perforation the secondary middling speed loading of long period are carried out on the stratum, thereby reach the purpose of secondary synergy.
The firing mount of packing in perforating gun, loads Pressure breaking bullet, barrier layer, middling speed Pressure breaking bullet at a high speed at the perforating bullet of packing in the firing mount, and is linked in sequence with detonating fuse; Separate the end dress rifle head of perforating bullet, other end dress gun breech between middling speed Pressure breaking bullet and the perforating bullet by barrier layer.Barrier layer is used to alleviate the impact of the detonation wave of perforating bullet to middling speed loading Pressure breaking bullet, avoids the middling speed Pressure breaking bullet to be lighted fast; The middling speed Pressure breaking bullet is by after the detonation wave decay of barrier layer to perforating bullet it being lighted, make its normal combustion under HTHP, producing the secondary pressure peak; Material by changing barrier layer and structure and the powder charge of middling speed Pressure breaking bullet design the duration of setting the secondary pressure peak.
The utlity model has simple in structurely, with low cost,, realize the purpose of secondary synergy by setting the duration of secondary pressure peak value.
Description of drawings:
Fig. 1 rifle body middle part dress middling speed Pressure breaking bullet
Segment section dress middling speed Pressure breaking bullet in Fig. 2 rifle body
Fig. 3 rifle body bottom dress middling speed Pressure breaking bullet
The specific embodiment
As shown in Figure 1, an end of perforating gun 7 is equipped with rifle head 1, other end dress gun breech 8, and firing mount 6 is contained in the perforating gun 7, and perforating bullet 2, high speed loads Pressure breaking bullet 3, barrier layer 4, middling speed Pressure breaking bullet 5 is linked in sequence by detonating fuse and be installed in the firing mount 6.
The detonation wave that produces after perforating bullet 2 detonates causes the detonation that loads Pressure breaking bullet 3 at a high speed, and reach higher pressure peak in moment, the duct that gases at high pressure are launched out by perforation, the stratum is carried out once loading at a high speed, and the perforating bullet below igniting successively, load Pressure breaking bullet at a high speed, perforating bullet, the perforating bullet detonation wave ignites and loads Pressure breaking bullet at a high speed, load at a high speed after detonation wave that Pressure breaking bullet produces decays through barrier layer 4, the middling speed of igniting again Pressure breaking bullet 5, make the middling speed Pressure breaking bullet be in fired state, keep higher pressure peak and continue the regular hour, reach the purpose of secondary synergy.
The propellant of middling speed Pressure breaking bullet described in the utility model powder charge is selected double base propellant for use, requires 120 ℃ of heatproofs, and as two fragrant magnesium-1, two cobalt-1, two cobalt-2, requiring quiet combustion speed simultaneously is the novel propellant of 15～30mm/s; Also can select the composite propellant of anti-combustion of heatproof+170 ℃～+ 210 ℃ for use.The shape of propellant can be tubular powder, fluting tubular powder, star hole medicine, the powder charge of wheel shape.
Barrier layer 4 material selection rubber described in the utility model, nylon, ABS plastic, barrier layer 4 is shaped as circle.
Composite perforation gun 7 described in the utility model is selected for use
Perforating bullet 2 is selected DP33RDX-5 (1), DP44RDX-1, DP44RDX-3 (5) perforating bullet 2 for use.
The " loaded " position of the middling speed Pressure breaking bullet 5 of built-in type secondary synergy composite perforator can also segmentation be contained in rifle body middle part as shown in Figure 2; or at rifle body bottom loading middling speed Pressure breaking bullet 5 as shown in Figure 3, or other similar mounting means disclosed in the utility model all belongs to the scope of the utility model protection.
