Description

An adjustable anti-clogging screw drill bit Technical Field

[0001] This utility model belongs to the field of screw drilling tools, specifically relating to an adjustable anti-clogging screw drilling tool. Background Technology

[0002] A screw drill is a positive displacement downhole power drill that uses drilling fluid as its power source, converting liquid pressure energy into mechanical energy. When the mud pumped out by the mud pump flows through the bypass valve into the motor, a certain pressure difference is formed between the motor's inlet and outlet, driving the rotor to rotate around the stator's axis. The rotational speed and torque are transmitted to the drill bit through the universal joint and drive shaft, thus realizing drilling operations. The screw drill mainly consists of four major assemblies: the bypass valve, the hydraulic motor, the universal joint, and the drive shaft. The screw motor is the main component of the drill. Many practical and theoretical analyses have shown that for the motor to work normally and effectively, and to prevent motor damage, the mud flow rate used on site should be within the recommended operating range. Otherwise, it will affect the motor efficiency and even increase wear. The performance parameters of the screw motor are the main performance parameters of the screw drill. The theoretical output torque of the motor is proportional to the motor pressure drop, and the output speed is proportional to the input mud flow rate. As the load increases, the drill speed decreases. Therefore, by controlling the reading of the pressure gauge on the surface and the pump flow rate, the torque and speed of the downhole drill can be controlled.

[0003] Currently available screw drills on the market have incomplete functions when users need to adjust the screw, which affects the use of the screw in certain situations. Furthermore, auxiliary tools are required when users need to install the screw drill, which increases the user's operating costs. Summary of the Invention
