A continuous tube of drilling torque-proof means
2014
The present invention relates to a coiled tubing drilling and completion technologies, and the drilling torque-proof apparatus and particularly to a continuous tube. The lower end of the inner wall of the threaded joint torque sleeve sealingly connected to the device, connected to the lower end of the joint sleeve placed outside the package and the torque sleeve, the inner wall of coupling sleeve mounted at the step stepped outer jacket lower torque, torque is locked by the locking sleeve blocks the connecting sleeve , Belleville springs disposed inward from the locking block, the stopper sleeve sealingly connected inside the threaded sleeve and to block the torque disc spring, the lower end of a threaded connecting sleeve seal the connection joint. The present invention permits to avoid damaging the continuous pipe coiled tubing drilling process due to excessive torque hindering the formation and the screw drill drill counter torque caused by the accumulation, screw drill failure problems, can be achieved when a large coiled tubing drilling WOB, high drilling drilling speed, further reducing the coiled tubing drilling cycle, reduce drilling costs.
