The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
With reference to Fig. 1, Fig. 2, the structure of the utility model device is, comprise and free pipe nipple 1, free pipe nipple 1 top (in upper end edge) and be provided with drill rod thread for being connected with drill string, free pipe nipple 1 bottom (outer, lower end) and be connected with suspension joint 2 tops (in upper end edge) by trapezoidal thread, the contact surface of freeing pipe nipple 1 and suspension joint 2 is provided with sealing II 12;
The outer, lower end of freeing pipe nipple 1 is provided with left-handed trapezoidal thread and sealed groove.
In the upper end of suspension joint 2, along being provided with left-handed trapezoidal thread and sealing surface, simultaneously, in the lower end of suspension joint 2, edge is provided with dextrorotation trapezoidal thread and sealing surface.
The outer, upper end of conversion pipe nipple 3 is provided with dextrorotation trapezoidal thread and sealed groove, and simultaneously, in the upper end of conversion pipe nipple 3, edge is provided with drill rod thread.
The operating principle of the utility model device is,
When carrying out lower drain line operation, if the bad weather of hurricane and so on occurs, while needing operating personnel's emergency escape, can connect upper kelly stand by freeing pipe nipple 1, connect the tubing string of having transferred by reducing pipe nipple 9 simultaneously, transfer together.When the urgent hanging tool of oil pipe is positioned at 10 meters left and right, blowout preventer set top, start heave compensator, slowly transfer by blowout preventer set, until sitting, the load-bearing joint 5 of the urgent hanging tool of oil pipe is placed on subsea production tree inner support step.Now, the antirotation keys 8 on swirel 7 is inserted in subsea production tree guiding anti-rotation groove, has stoped the urgent hanging tool of oil pipe and has transferred the rotation of tubing string.Then, by clockwise dextrorotation drill string, to freeing pipe nipple 1, apply the shackle moment of torsion, make and free pipe nipple 1 disengaging suspension joint 2.Then, give upper lifting force of drill string, regain and free pipe nipple 1, close blowout preventer set shear ram or blind rams, the operating personnel withdraws.
