摘要： The present invention is a fluid handling device such as a helicoidal pump or motor having a stator (8) formed by an elastomer material in which a plurality of fibers (22-25; 30-32) are encapsulated. Preferably, the fibers form a network of interlaced fibers extending in two or more directions. The fiber network preferably forms multiple layers of flexible fabric encircling the stator axis. In addition, a group of fibers (26) can extend radially through the fabric layers. The fibers increase the strength, the stiffness of the elastomer, and also create heat conduction paths that improve the heat transfer within the stator core, thereby preventing overheating of the elastomer.

摘要： A system for damping vibration in a drill string can include a magnetorheological fluid valve assembly having a supply of a magnetorheological fluid, a first member, and a second member capable ofmoving in relation to first member in response to vibration of the drill bit The first and second members define a first and a second chamber for holding the fluid Fluid can flow between the first and second chambers in response to the movement ofthe second member in relation to the first member The valve assembly can also include a coil for inducing a magnetic field that alters the resistance ofthe magnetorheological fluid to flow between the first and second chambers, thereby increasing the damping provided by the valve A remanent magnetic field is induced during operation that can be used to provide the magnetic field for operating the valve so as to eliminate the need to energize the coils

摘要： A stabilizer (1) especially adapted for use with an drill string having an eccentric drilling element, such as a bi-center bit. The stabilizer (1) has a pair of circumferentially displaced blades (18) that lie in a common circumferential plane and extend from a rotatable sleeve (20) supported on the stabilizer body (50) , as well as a stationary blade (17). The rotating blades (18) are aligned with the stationary blade (17) when in a first circumferential orientation and are disposed so that the mid-point between the rotating blades (18) is located opposite the stationary blade (17), thereby providing full-gauge stabilization, when the rotating blades (18) are in a second circumferential orientation. A magnetic system (60) senses the circumferential orientation of the rotating blades (18) and transmits the information to the surface via mud pulse telemetry. A piston (141) actuated by the drilling mud locks the rotating blades (18) into the active and inactive positions. A brake shoe (59) located on the distal end of each rotating blade (18) provides contact with the walls of the borehole and serves as a support pad (59) for a formation sensor (45).
