Described stopping lock gripping members comprises retreat stop block and lock-screw, and retreat stop block coordinates with gun barrel, and retreat stop block is fixed on joint by lock-screw.
Described dredging flow groove is six, is evenly distributed in righting female joint.
The external diameter of described dredging flow groove is greater than compound cartridge case external diameter.
Described righting female joint outer wall is provided with wiper block, and wiper block two ends are by domatic transition.
Dredging flow groove is formed between described adjacent two wiper blocks.
Employing the utility model has the advantage of:
1, in horizontal well composite gun perforation process; the utility model is in perforating gun string; righting is carried out to perforating gun; reduce perforating gun string and sleeve friction contact surface; solid compound cartridge case outside protection perforating gun; avoid gun barrel jacket-type cartridge case in horizontal segment and pit shaft friction, during raising perforation, medicine cover forms fault offset space protection down-hole casing and the perforating gun of high energy gas, also can improve the handling capacity in horizontal well pit shaft.
2, the utility model controls the gap between device maximum outside diameter and pit shaft, has both met industry standard gap, plays again protection jacket-type compound cartridge case; The distribution of chute, improves the drainage area of high energy gas during perforation, reduces compound cartridge case corresponding local casing damage and avoids perforating gun to squeeze and ruin.
3, the utility model solves connectivity problem between gun barrel, junction design locking mechanism, can prevent perforating gun from moving back the situations such as button when vibrations or torsional deflection, and the property passed through improving device, by domatic transition, is intended in wiper block two ends.
