Specific embodiment
This utility model is further described below in conjunction with the accompanying drawings, protection domain of the present utility model be not limited to
It is lower described：
As shown in Fig. 1～Fig. 2, limit-type abrasive perforating mechanism, including stop 1 and abrasive perforating rifle 2, described is spacing
Device 1 is for cylinder and is provided with inner chamber, and three groups of through holes 3 are provided with the side wall of stop 1, and slips 4 is placed with through hole 3, and through hole 3 is leaned on
The nearly medial wall position of stop 1 is provided with U-shaped baffle plate 5, and profile and the diameter of through hole 3 of U-shaped baffle plate 5 match, slips 4
One end be fixed in the groove, the other end of slips 4 is stretched out outside through hole 3, and through hole 3 is provided with the lateral surface of stop 1
Curved baffle 9, curved baffle 9 is in close contact and curved baffle 9 is fixed on stop 1 by screw, arc with stop 1
Spring 6 is provided between baffle plate 9 and U-shaped baffle plate 5, spring 6 is enclosed within slips 4, when stop 1 is connected with current, current are passed through
The inner chamber of stop 1, U-shaped baffle plate 5 overcomes the resistance of spring 6 by slips 4 toward extrapolation in the presence of hydraulic pressure；The bottom of stop 1
It is connected with abrasive perforating rifle 2, the side of abrasive perforating rifle 2 is provided with multiple touches mouth 7, inner chamber, sandblasting of the current through stop 1
The inner chamber of perforating gun 2 is projected from the perforation tunnel of nozzle 7, and the bottom of abrasive perforating rifle 2 is fixed with gravity post；Stop 1, sandblasting
Perforating gun 2 and gravity post are arranged in sleeve pipe 8, and the nozzle 7 on abrasive perforating rifle 2 is arranged perpendicular to the side wall of sleeve pipe 8, weight
