    摘要: An orienter, particularly on coiled tubing or small diameter drill pipe, includes a motor, turbine, or other device for selectively converting the rotational kinetic energy produced from fluid flow through the device to mechanical power, and applying the mechanical power to a downhole tool through a gear train for orienting the downhole tool. The orienter is utilized during directional drilling and other operations such as well intervention, fishing, and multilateral re-entry operations. The downhole tool preferably includes a steerable mud motor. In one embodiment, the direction of the borehole is controlled by azimuthal rotation of the orienter of the present invention in response to downlink commands from the surface by changing fluid flow rate through the orienter in a predefined series of steps.

    摘要: A technique is provided to facilitate pumping of fluids in a well. A submersible pumping system utilizes a submersible motor to power a submersible pump. A motor protector works in cooperation with the submersible motor to protect motor fluid within the submersible motor and to reduce differential pressures between the internal motor fluid and the external well fluid. The motor protector incorporates a piston slidably sealed within an interior cavity of the motor protector for movement to reduce undue differential pressures.
