Abstract: A drilling system includes a drill string for connecting with a drill bit for drilling a borehole, a fixed stabilizer fixed on the drill string, and an active stabilizer including a body and actuators connecting the body and the drill string. The actuators are capable of driving the drill string away from a center of the borehole with a displacement. The body has an outer surface for contacting a wall of the borehole, an inner surface facing the drill string, and at least one guiding portion projecting from the inner surface and each defining at least one groove. The drill string includes at least one sliding portion slidable within the at least one groove respectively to constrain movement between the drill string and the active stabilizer along an axial direction of the drill string and guide movement between the drill string and the active stabilizer perpendicular to the axial direction.

Abstract: A power integrated system includes a gas storage unit, a gas driven generator, a power bus, a drilling rig, oil/gas production equipment, and a gas reformer. The gas storage unit is used for storing natural gas. The gas driven generator is used for generating electric power based on the stored natural gas. The power bus is used for receiving the electric power generated by the gas driven generator. The drilling rig is used for being driven by the electric power from the power bus. The oil/gas production equipment is used for being driven by the electric power from the power bus and for generating associated gas. The gas reformer is used for reforming the associated gas and supplying the reformed gas to the gas storage unit.

Abstract: A system for steering a drilling device comprising a drill pipe, is provided therein, the system comprising: a hoop sleeved on the drill pipe of the drilling device and having an outer diameter substantially equal to an inner diameter of a hole to be drilled; and a steering driving mechanism provided between the hoop and the drill pipe, for controlling a radial displacement of the drill pipe relative to a center axis of the hole to be drilled while drilling. The steering driving mechanism comprises one or more sub-mechanisms for connecting the hoop and the drill pipe and driving the drill pipe to move inside the hole, wherein each of the sub-mechanisms comprises an actuator adjustable in length, and a link element with one end rotatably coupled to the actuator and the other end rotatably coupled to hoop.
