Abstract: 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.

Abstract: Disclosed are a wireless remote control method and system for controllable rotary sliding guiding drilling. An upper end of a controllable rotary sliding guiding drilling mechanism is provided with a drill rod; and the wireless remote control system for controllable rotary sliding guiding drilling further comprises: an MWD arranged at a lower end of the controllable rotary sliding guiding drilling mechanism; a bent screw drill tool mounted at a lower end of the MWD; a drill bit mounted at a lower end of the bent screw drill tool, the drill bit being connected with the bent screw drill tool through a connector; and a clutch module mounted on the controllable rotary sliding guiding drilling mechanism, the clutch module comprising an electromagnetic valve, a processor, an internal pipe pressure sensor, an external pipe pressure sensor and a wireless data transmission module.

Abstract: A traditional Chinese medicine compound composition with immune bidirectional regulation effect and its preparation method and applications are disclosed. The traditional Chinese medicine compound composition with immune bidirectional regulation effect is prepared by compounding a volatile oil obtained after heating and refluxing of Schizonepetae herba and an extract jointly extracted by Schizonepetae herba extract residue, Astragali radix and Atractylodes macrocephala in the disclosure. The traditional Chinese medicine compound composition has no side effects and remarkable effect, and the traditional Chinese medicine compound composition disclosed by the disclosure can be used as a dietary supplement or health food raw material to regulate allergic reaction and low immunity. The traditional Chinese medicine compound composition disclosed by the disclosure is suitable for promotion and application.
