The invention discloses a guiding force measuring and control device and a guiding force calibrating method of a rotary guiding drilling system, which can carry out measuring and control and calibrating to the rotary guiding drilling system. The guiding force measuring and control device of the rotary guiding drilling system comprises a three-wing measuring and control tray, three thrust sensors, a data processor, and fixed screws for installing the thrust sensors, wherein the hollow three-wing measuring and control tray comprises three convex wing ribs; a guiding unit of the rotary guiding drilling system is extended into a hollow structure of the three-wing measuring and control tray, and the three wing ribs of the three-wing measuring and control tray are respectively corresponding to three guiding palm-shaped parts of the guiding unit; each wing rib is provided with the fixing screw thereon; each fixing screw is provided with a thrust sensor on the part positioned in the hollow structure of the three-wing measuring and control tray; and top heads of the three thrust sensors are one by one correspondingly propped against the three guiding palm-shaped parts of the guiding unit. The guiding force measuring and control device and the guiding force calibrating method disclosed by the invention can be applied to measuring, controlling and calibrating the guiding force of the rotary guiding drilling system.
Description
technical field [0001] The invention relates to a rotary steerable drilling system, in particular to a steering force measurement and control device of the rotary steerable drilling system and a calibration method for the steering force of the rotary steerable drilling system. Background technique [0002] The rotary steerable drilling system is equipment in the field of directional wells, which can greatly improve the efficiency and success rate of directional well operations. key technology. [0003] Rotary steerable drilling system can be divided into push-and-pull type and point-to-point type according to the structural principle. The push-on type uses three or more wing ribs to open and push against the well wall to guide the drill bit. However, there is no reliable measurement and control technology for the steering force and steering angle of the push-on rotary steerable drilling system. Contents of the invention [0004] The technical problem to be solved by the ...
