The torque generated by the screw drill tool only turns the drill bit, which can dramatically decrease drill pipe wear; The screw drill tool can be incorporated into special BHA to realize high built-up rate or screwed to orientating tool to perform continuously controlled kick-off; Output torque of the screw drill tool is in linear relationship with drilling fluid differential pressure generated by the hydraulic motor;
