Abstract: A remote-controlled adjustable-speed screw drill for gas-drive hydraulic-motive during gas drilling is provided, including a piston speed control system, a motor assembly, a cardan shaft assembly and a transmission shaft assembly which are connected with each other from up to down in sequence. The motor assembly includes air inlets, a cam, air cylinders, pistons, a connecting rod, air outlets, liquid inlets, hydraulic cylinders, liquid check valves, a liquid storage chamber, liquid outlets, a liquid injecting chamber, a liquid injecting hole, an anti-drop cap, a rotor, a stator, and a motor assembly housing. The present invention utilizes the high-pressure gas injected by the gas drilling to drive the pistons to move back and forth at high-speed, so as to drive the incompressible liquid within the driving screw to achieve the self-circulating motion, and the screw rotor is driven to rotate by the liquid.

Abstract: A pressure pulse communication system and method during gas drilling are provided. The system includes a downhole solenoid valve module and a sensor module, where the downhole solenoid valve module includes a valve body, a gas inlet, a piston micro-hole, a moving piston, a piston return spring, a piston cylinder, a gas outlet, a piston pressure relief hole, a solenoid valve spring, a solenoid valve, a battery, a pressure balancer, and a rubber seal. The pressure pulse communication system and method generate pressure pulses by changing the internal pressure of a drill pipe, such that a surface pressure sensor continuously receives the pressure pulses, thereby achieving the purpose of acquiring downhole temperature, pressure, and well inclination angle data.
