Abstract
The utility model relates to a cluster detonation perforator, which mainly solves the problems that the hole density of the present perforator is limited and the interference between the bombs is existed, characterized in that the outer wall of the same cross section of a bomb rack (2) is fixed at least three perforating bombs (3); the perforating bombs (3) are homogeneously distributed along the circumferential direction; an axial center of the bomb rack (2) is provided with a blasting cord (4); and a booster hole (5) of the perforating bombs (3) is centralized on the blasting cord (4). The cluster detonation perforator can fully advance the arranging density of the perforating bombs, and makes the hole density of the perforator to reach more than 60 holes per meter, thereby effectively reducing the affect of the interference between the bombs and guaranteeing the whole capability of the perforator.
Description
Technical field:
The utility model relates to a kind of oil field perforation device, especially bunch formula perforator that detonates.
Background technology:
The high shot density perforator that uses in the present stage oil field adopts many helical arrangement such as phase angle mode of 135 °/45 ° phase angle or 138 °/42 ° to realize the highdensity arrangement of perforating bullet, in order to have reduced the pressure differential inside and outside the pit shaft, improve the oil well recovery ratio, but this arrangement mode, the Kong Mi of perforator is restricted, generally be no more than 40 hole/rice, and exist between bullet and disturb, limited the performance of the overall performance of perforator.
The utility model content:
Existing perforator hole is close to be restricted and to have a deficiency of disturbing between bullet in order to overcome, the utility model provides a kind of bunch of formula perforator that detonates, this bunch formula perforator that detonates can fully improve the arranging density of perforating bullet, make the Kong Mi of perforator reach 60 holes/more than the rice, effectively reduce the influence of disturbing between bullet, guaranteed the overall performance of perforator.
The technical solution of the utility model is: this bunch formula perforator that detonates comprises the body of a gun, firing mount is arranged in the body of a gun, fixing at least 3 launch hole bullets on the same cross section outer wall of firing mount, perforating bullet is along circumferentially evenly distributing, there is 1 detonating fuse at the place, axle center of firing mount, and the propagation of explosion hole of perforating bullet is collected at the detonating fuse place.
Above-mentioned perforating bullet is 3; Perforating bullet is multilayer and each layer along axially being interspersed of firing mount 2, and its interlayer phase angle is 120 °/60 °, 90 °/45 ° or 60 °/30 °.
The utlity model has following beneficial effect: owing to take such scheme, the mode that adopts every layer at least three launch hole bullet to detonate simultaneously, guaranteed the symmetry of detonation product field, the phase angle is adopted 120 °/60 ° or 90 °/45 ° or 60 °/30 °, the spacing and the perforating bullet spacing of every interlayer have been increased, effectively reduce the influence of disturbing between bullet, can fully improve the arranging density of perforating bullet, make the Kong Mi of perforator reach 60 holes/more than the rice, reach the desirable requirement of detonating of perforator, guarantee the performance of perforator performance, thereby obtain better perforation completion effect.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model.
The 1-body of a gun among the figure, 2-firing mount, 3-perforating bullet, 4-detonating fuse, 5-propagation of explosion hole.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this bunch formula perforator that detonates comprises the body of a gun 1, firing mount 2 is arranged in the body of a gun 1,3 launch hole bullets 3 on the same cross section outer wall of firing mount 2, perforating bullet 3 is along circumferentially evenly distributing, perforating bullet 3 for multilayer and each layer along axially being interspersed of firing mount 2, its interlayer phase angle is 120 °/60 °, 90 °/45 ° or 60 °/30 °.There is 1 detonating fuse 4 at the place, axle center of firing mount 2, and the propagation of explosion hole 5 of perforating bullet 3 is collected at detonating fuse 4 places.
During actual the use, every layer at least three launch hole bullet 3 detonates simultaneously, guaranteed the symmetry of detonation product field, the phase angle is adopted 120 °/60 ° or 90 °/45 ° or 60 °/30 °, the spacing and perforating bullet 3 spacings of every interlayer have been increased, effectively reduce the influence of disturbing between bullet, can fully improve the arranging density of perforating bullet 3, make the Kong Mi of perforator reach 60 holes/more than the rice, reach the desirable requirement of detonating of perforator, guarantee the performance of perforator performance, thereby obtain better perforation completion effect.
