Abstract
The utility model relates to an axle sleeve type perforating and fracturing combined apparatus, which belongs to the technical field of petroleum exploitation and stratum alteration. The utility model is composed of fracturing gunpowder 3, a bullet holder 4, perforating bullets 5, a perforating gun barrel 7, etc., wherein, the perforating bullets 5 are arranged on the bullet holder 4, a detonating cord 6 is inserted into the perforating gun barrel 7, and the fracturing gunpowder 3 is piecewise penetrated into the perforating gun barrel 7 from bottom to top, and is fixedly pasted with the outer surface of the perforating gun barrel 7. The utility model has the advantages that perforation and fracture are integrated, and the per meter loading quantity of the utility model can reach 11.04 kg; the utility model has strong crack making ability and long crack prolongation, and detonator and gunpowder can be completely isolated by the gun barrel; the perforating gun barrel is completely made from that of conventional perforating guns, having no need of other higher strength of steel, and thus, the cost is low.
Description
The utility model relates to a kind of combined apparatus for perforation fracturing in oil development, the stratum renovation technique.
At present, deep penetration compound technique of perforating commonly used, exactly perforating technology and High-Energy Gas Fracturing Technology are combined effectively, mainly contain two kinds of form of structure, the one, adorn flammable firing mount in the body of a gun, the 2nd, under perforating gun, hang caseless cartridge, its purpose is exactly behind perforation, further extend formation fracture, preceding a kind of big-entry-hole of deepening, but its shortcoming is: and explosive payload is little, and pressure is short action time, flammable firing mount treatment process program is many, the structure relative complex, and higher to composite perforation gun tubing requirement of strength, strengthened cost perforation quantity few (8-10 hole/rice), a kind of suspension caseless cartridge formula composite fracturing in back, can play the effect of high enegry gas fracturing to preforation tunnel, but because the gas after the burning of perforating gun tail end bottom has stronger upwards thrust to tubing string, safety is not high yet, owing to the restriction of perforating gun length, it is limited to carry caseless cartridge simultaneously.
The purpose of this utility model is: provide a kind of and satisfied normal perforation needs and can carry big propellant dose and the strong combined apparatus for perforation fracturing of width generation capacity simultaneously again
The utility model is achieved in that by priming device 1, go up that plate washer 2, pressure break medicine 3, firing mount 4, perforating bullet 5, detonating fuse 6, perforation casing 7, tail are stifled 8, lower baffle 9, manometer 10 are formed, perforating bullet 5 places on the firing mount 4, detonating fuse 6 inserts in the perforation casing 7, pressure break medicine 3 penetrates from bottom to top piecemeal on the perforation casing 7 and with perforation casing 7 external surfaces bonding and fixes, tail stifled 8 is equipped with in the bottom of perforation casing 7, the upper and lower part of pressure break medicine 3 has last plate washer 2 and lower baffle 9 respectively, and the upper and lower part of perforation casing 7 has priming device 1 and manometer 10 respectively.
Advantage of the present utility model is: perforating and fracturing is integrated, every meter explosive payload of this device can reach 11.04kg, width generation capacity is strong, fracture extension is long, because gun barrel isolates explosive, gunpowder fully, got rid of that explosive, gunpowder load in mixture unsafe factors such as explosive in the existing deep penetration composite gun perforation, perforating gun adopts conventional perforating gun fully, do not need the steel of selecting for use other intensity higher, with low cost.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model is achieved in that by priming device 1, go up that plate washer 2, pressure break medicine 3, firing mount 4, perforating bullet 5, detonating fuse 6, perforation casing 7, tail are stifled 8, lower baffle 9, manometer 10 are formed, perforating bullet 5 places on the firing mount 4, detonating fuse 6 inserts in the perforation casing 7, pressure break medicine 3 penetrates from bottom to top piecemeal on the perforation casing 7 and with perforation casing 7 external surfaces bonding and fixes, tail stifled 8 is equipped with in the bottom of perforation casing 7, the upper and lower part of pressure break medicine 3 has last plate washer 2 and lower baffle 9 respectively, and the upper and lower part of perforation casing 7 has priming device 1 and manometer 10 respectively.
Its assembling process is: at first assemble conventional perforating gun, promptly perforating bullet 5 is packed into and press on the firing mount 4 that the phasing parallactic angle offers perforating bullet, and detonating fuse 6 installed on request, insert in the perforation casing 7, perforating bullet 5 phase angles that distribute on the firing mount 4 should be corresponding consistent with the blind hole phase angle offered on the perforation casing 7, locate the back pressure break medicine 3 piecemeal from down (gun breech) upwards (rifle head) penetrate on the perforation casing 7, and install lower baffle 9 and tail stifled 8, eyelet on the pressure break medicine 3 should be corresponding consistent with the blind hole on the perforation casing 7, pressure break medicine 3 surfaces are through covering processing deeply, guarantee the reliability and stability of burning, inner surface is smeared adhesive with fixing with perforation casing 7 external surfaces bondings, adorned pressure break medicine 3 piecemeal after, load onto plate washer 2 above that, and add Upper gasket, connect initiator 1 then.
