The beneficial effects of the utility model are：1）Save operating cost.The device can realize marine riser near mud line
Fast quick-detach avoids marine riser being caused to scrap with hydraulic cutter cutting, can retain complete riser joints, facilitate secondary recovery
It uses, avoids the waste of marine riser product, saved probing cost of winning.
2）Installing and dismounting speed is fast.Only need to rotate 160mm or so after the cooperation of male and female connector can be installed in place, and equally tear open
Upper lifting pipe string when unloading, reversion cut pin and dismounting can be realized, and substantially reduce the drilling engineering activity duration.
3）Properties of product are reliable.It is high to hang bulk strength, tension, bending resistance, the internal pressure strength of connector are above tube body, break pin
Nail has certain anti-rotating function, and shearing resistance torque is 23000Ib-ft, and multi-functional makes product structure stabilization, dependable performance.
4）Good seal performance.Sealing ring material uses nitrile rubber, has the characteristics that anticorrosive, temperature resistant range is big, anti-aging,
Internal pressure reaches 18.3MPa, has ensured the sealing performance and durability of product.
In conclusion a kind of torsion that we research and develop is cut, buckle and latchplate performance is excellent, and not only avoiding prospect pit needs
The complicated process of marine riser is cut with hydraulic cutter, while avoids the wasting of resources, has saved operating cost, is had good
Generalization.
