Abstract: The disclosure concerns oil drilling technology, and specifically an all-metal intelligent control motor (AMIM). The AMIM comprises an electric control module, a power module and a transmission module. The electric control module determines the axial position of the connecting rod valve through an electromagnet and controls the connection between the connecting rod valve and the piston through an electric motor. The hydraulic pressure of drilling fluid and the spring reaction force in the power module push a double worm to move axially and circumferentially under the action of internal teeth on the inner surface of shell. A one-way bearing ensures that the power module only transmits unidirectional motion. The transmission module axially limits the power module through TC bearings and transmits circumferential motion, drilling pressure and torque to the lower drilling tool. The AMIM is suitable for all kinds of deep well exploration, with a stronger drilling force, a lower cost and a higher applicability.

Abstract: A method with which mechanical properties of the interface of the fiber reinforced thermoplastic resin matrix composite material can be improved by conducting grafting on surfaces of materials. A carbon fiber (CF) and a polymethyl methacrylate resin (PMMA) are subjected to interface modification treatment to introduce active carboxyl groups to the surfaces of the materials. Then, hexamethylene diisocyanate (HDI) is used as a coupling layer for connecting the carboxyl groups on the surfaces of the carbon fiber and on the surfaces of the polymethyl methacrylate resin to form a “molecular bridge”. Accordingly, the interface binding force between the resin and the fiber is improved by chemical grafting. A modified carbon fiber reinforced polymethyl methacrylate composite material sample (CF/PMMA) is prepared by a thin film lamination method, and the composite material sample prepared is subjected to a microscopic verification testing of the validity of the method provided in the present disclosure.
