Abstract:
The static push-the-bit articulated high-built-rate rotary steerable tool has the main body of a non-rotary measurement and control unit articulated with the main body of a non-rotary actuator, rather than an integral structure. Due to the fact that the drilling tool is easy to bend in a wellbore, the bending stress in an upper portion of the steerable tool is low, and the consumption of the pushing force for bending deformation of the drilling tool is minimized. Since the steering sleeve around the main body of a load-bearing actuator only slides along the well wall in an axial direction without rotational friction there-between, the service life of the steering sleeve is long. Besides, since hydraulic pressure is used instead of pressure difference of mud to act on the pistons to form the pushing force, the pushing force is greatly improved, and the sealing life of the pistons is longer.

Claim (Index 1):
A static push-the-bit articulated high-built-rate rotary steerable tool, comprising a rotary mandrel ( 7 ), a drill bit shaft ( 15 ), a universal joint ( 13 ) connecting the rotary mandrel ( 7 ) with the drill bit shaft ( 15 ), a first non-rotary steering sleeve ( 4 ) and a second non-rotary steering sleeve ( 12 ), wherein,\n the rotary mandrel ( 7 ) is articulated with the universal joint ( 13 ), so as to transmit drilling pressure and torque for drilling to a drill bit and realize universal articulation of the first non-rotary steering sleeve ( 4 ) and the second non-rotary steering sleeve ( 12 ) as well; and the first non-rotary steering sleeve ( 4 ) and the second non-rotary steering sleeve ( 12 ) are isolated from the rotation of the rotary mandrel ( 7 ) by means of an upper mud bearing ( 6 ), a lower mud bearing ( 5 ) and a near-bit-end mud bearing ( 14 ), so that the first non-rotary steering sleeve ( 4 ) and the second non-rotary steering sleeve ( 12 ) are kept in a quasi-stationary or non-rotary state with respect to the ground.
