摘要： A technique facilitates steering of rotary steerable systems when conducting directional drilling operations. A rotary steerable system is combined with a pressurized oil system which delivers oil to a piston actuated mechanism. The pressurized oil provides precise, long-lasting control over the orientation of the bottom hole assembly and the drill bit to facilitate directional drilling of boreholes through subterranean formations.

摘要： A method, system and apparatus for steering a drill string employ, an eccentric steering device. The eccentric steering device may comprise an eccentric sleeve configured for mounting exterior to a portion of the drill string and permitting the drill string to rotate within the eccentric sleeve and a brake positioned to selectively cause rotation of the eccentric sleeve with the drill string. The eccentric steering device may further comprise one or more bearings positioned between the eccentric sleeve and the drill string.

摘要： A directional drilling system, a drilling hammer and a fluid flow telemetry modulator use a plurality of magnets arranged to convert rotational motion into reciprocating linear motion. Various types of motor can provide rotational motion to a part of the magnets and various linkages and other devices can cause steering or operation of a modulator valve. A torsional drilling hammer uses a plurality of magnets arranged to convert reciprocating linear motion into reciprocating rotational motion. A motor and linkage drives the linearly moving part of the magnets, and the rotating part provides torsional impact be striking the linearly moving part of the magnets.
