Illustratively, a long horizontal section of a horizontal well, which is conventionally drilled using sliding directional drilling, is installed in the drill string at a distance of 50 meters from the drill bit, with the segmented rotary counter-torque tool connected to the upper string of tubulars and the lower string 45 connected to the lower string of tubulars. Along with the gradual lengthening of the horizontal section of the horizontal drilling well, when the supporting pressure is 30 tons, the reaction torque of the screw drill is suddenly and rapidly increased after the bit pressure is suddenly released, the tool surface is possibly unstable, the tool surface is swung again at the moment, the push-pull rod 11 is lifted up in an electric control or hydraulic mode after the tool surface is swung, the torque clutch mechanism 1 starts to work, the push-pull rod 11 rises along the axis direction of the push-pull rod 11 and is separated from the gear shaft 16, the torque of the upper pipe column and the torque of the lower pipe column are separated at the moment, the rotary table can rotate to feed the drill at the rotating speed of 60r/min, and the small bit pressure is applied to carry out directional drilling.
During the directional drilling process, in order to overcome the reactive torque of the screw drill (assuming that the reactive torque is 8KN.m), the preset torque of the friction plate torque retaining mechanism 3 before the sectional rotary type overcoming reactive torque tool enters the well is 5KN.m, so that the sectional rotary type overcoming reactive torque tool can keep 5KN.m of positive torque rotation underground, but not enough to overcome the 8KN.m of the screw drill. If the pump pressure is 20MPa at this moment, the friction ring torque-increasing mechanism 2 of the segmented rotary type counter-torque tool plays a role, and can provide 3KN.m forward torque for balancing the counter-torque. The reaction torque absorbing mechanism 4 can continuously absorb the fluctuating torque to achieve the purpose of stabilizing the tool face.
