摘要： The invention refers to a rotary steerable drilling tool having a tool collar and a bit shaft. The bit shaft is supported within the tool collar for pivotal movement about a fixed position along the bit shaft. Moreover, the rotary steerable drilling tool includes a variable bit shaft angulating mechanism, located within the interior of the tool collar. The variable bit shaft angulating mechanism includes a motor, an offset mandrel, and a variable offset coupling. The motor is attached to the upper end of the offset mandrel and adapted to rotate the offset mandrel. The upper end of the variable offset coupling is uncoupleably attached to an offset location of the lower end of the offset mandrel, and the upper end of the bit shaft is rotatably coupled to the variable offset coupling. The rotary steerable drilling tool also includes a torque transmitting coupling adapted to transmit torque from the tool collar to the bit shaft at the fixed position along the bit shaft. Finally, a seal system is adapted to seal between the lower end of the tool collar and the bit shaft.

摘要： An actively controlled rotary steerable drilling system for directional drilling of wells having a tool collar rotated by a drill string during well drilling. A bit shaft has an upper portion within the tool collar and a lower end extending from the collar and supporting a drill bit. The bit shaft is omni-directionally pivotally supported intermediate its upper and lower ends by a universal joint within the collar and is rotatably driven by the collar. To achieve controlled steering of the rotating drill bit, orientation of the bit shaft relative to the tool collar is sensed and the bit shaft is maintained geostationary and selectively axially inclined relative to the tool collar during drill string rotation by rotating it about the universal joint by an offsetting mandrel that is rotated counter to collar rotation and at the same frequency of rotation. An electric motor provides rotation to the offsetting mandrel with respect to the tool collar and is servo-controlled by signal input from position sensing elements such as magnetometers, gyroscopic sensors, and accelerometers which provide real time position signals to the motor control. In addition, when necessary, a brake is used to maintain the offsetting mandrel and the bit shaft axis geostationary. Alternatively, a turbine is connected to the offsetting mandrel to provide rotation to the offsetting mandrel with respect to the tool collar and a brake is used to servo-control the turbine by signal input from position sensors.
