Background
The coiled tubing drilling operation is different from the conventional drilling operation by using a drilling machine and a drill rod, and because the coiled tubing body cannot rotate, a steering tool is required to adjust the tool orientation, so that the borehole track is ensured to extend to the target area according to the design requirement. The wellhead rotary steerable as proposed in CN201020203336.5 prolongs the service life of the rubber core, but does not allow the rotary steerable to have a strong torque. When the drill tool is being reversed towards the need using the coiled tubing side drilling, the string is lifted off the rock. The weight on bit is reduced to zero. During circulation, the pressure drop of the motor can push the piston to move so as to drive the pipe column to rotate. . The orientation parameters of the tool are transmitted to the surface by the wireless magnetic positioning tool. After confirming the direction, the locking direction is pressed down to start drilling, the locked angle is kept until the new angle needs to be adjusted, and the actions are repeated until the drilling is completed to the design purpose when the tool orientation needs to be adjusted. The expansion pipe proposed in patent number CN201720606062.6 is connected with an expansion core rotary guide which is used for extending into an inner hole of a pipe to be expanded and has taper at one end of an expansion rod extending out of an expansion shell, but the rotary guide is difficult to achieve a minimum adjustment angle.
