Background
The horizontal well technology is a main technology for developing deep and unconventional oil and gas resources, well track guiding control is required for horizontal well drilling, and the conventional horizontal well guiding drilling comprises two types of rotation guiding and bent screw sliding guiding.
The rotation of the drill string is one of the most effective means for solving the problem of 'pressure supporting', for example, the speed increasing rate of a drill string torsion pendulum system based on the reciprocating rotation of the drill string is over 30 percent, but the system cannot be applied to a deep well, and the speed increasing rate of the well depth of more than 3000m is limited. A twin-screw clutch is developed by the Canada HydroClutch company, one screw in the tool provides a rock breaking torque for a drill bit, and the other screw resists the reaction torque transmitted to a drill rod by the broken rock of the drill bit, but the pressure consumption of the tool is 5-10MPa higher than that of a conventional drilling tool combination, the requirements of site working conditions cannot be met, the tool surface cannot be accurately controlled, and an engineering application test is not seen yet. The technical research of isolating drill column rotation is developed in Chongqing drilling and the like in China, the functions of separating and combining the drill columns are realized, however, the problems of uncontrollable tool surface and overlong lower static drilling tool still exist (more than 700 meters), and three technical bottlenecks of difficult control of well track, low drilling speed and pure drilling time effectiveness and high drilling sticking risk still exist in bent screw sliding guiding.

The patents CN201710028105.1, US5458208, CN 2651413Y, CN105525875a, etc. invented the clutch mechanisms, but these clutch mechanisms perform clutch operation with a large rotation angle of over 30 ° in one time, and the control precision of the tool face is low; due to the limitation of mechanical property, the clutch time is longer, the rotating speed of the drill rod is low, and the requirement of high rotating speed is difficult to adapt.
