Provided is a two-stage reverse-torque bent screw orientation tool. An existing bent screw orientation technology has the technical problems of large friction resistance, difficult control of a borehole track, a low drilling speed and the like, and restricts economic, safe and long-acting development of oil and gas. In order to solve the above problems, the two-stage reverse-torque bent screw orientation tool is invented and composed of a first-stage clutch mechanism and a second-stage clutch mechanism, and the first-stage clutch mechanism and the second-stage clutch mechanism are both composed of a battery, a battery compartment, a pressure sensor, an electromagnetic valve, a body, a plug, a piston, an outer tooth cylinder, an inner tooth cylinder, a transmission cylinder, a connecting cylinder, a bearing, a limiting cylinder, a lower joint, a thrust bearing, a battery compartment, a circuit board, a cover plate and the like.
A two-stage reverse-torque bent screw orientation tool, composed of a first-stage clutch mechanism (100) and a second-stage clutch mechanism (200), wherein the first-stage clutch mechanism (100) and the second-stage clutch mechanism (200) are both composed of a fixing screw A (1), a battery plug (2), a cover plate (3), a circuit board (4), a battery (5), a battery compartment (6), a pressure sensor (7), an electromagnetic valve (8), a body (14), a plug (15), a fixing screw B (17), a piston (18), an outer tooth cylinder (20), an inner tooth cylinder (21), a transmission cylinder (22), a bearing A (23), a limiting cylinder (24), a bearing B (25), a lower joint (26), a connecting cylinder (27) and a diamond compact (28);
