摘要： A technique facilitates controlling the direction of drilling when using a rotary steerable system to drill a borehole. The method comprises processing parameters related to operation of a rotatable collar of the rotary steerable system. The parameters are used in cooperation with characteristics of actuators to control the positioning of an actuator tool face which, in turn, controls the drilling orientation of the rotary steerable system.

摘要： Exhaust pressure from at least one actuator (34,36) which can tilt joint (6) of a bottom hole assembly (4) can be utilized to determine the direction (26) tiltable joint (6) is pointing (e.g., orientation, angular displacement, and/or inclination and azimuth). In one embodiment, a known exhaust pressure can be correlated to a known orientation and/or angular displacement, and the measured exhaust pressure can be compared to the known exhaust pressure to determine the orientation and/or angular displacement. In another embodiment, the flow rate of fluid exhausted from an actuator (34,36) can be derived from the exhaust pressure. The exhaust flow rate can then be used to calculate the state of actuation, which can allow determination of the angular displacement of the tiltable joint (6). Orientation and/or angular displacement with respect to the bottom hole assembly (4) can be resolved into an inclination and azimuth with respect to a formation (14).
摘要翻译：可以利用能够倾斜底部钻具组合（4）的接头（6）的来自至少一个致动器（34,36）的排气压力来确定可倾斜接头（6）的方向（26）指向（例如，取向，角位移和/或倾角和方位角）。在一个实施例中，已知的排气压力可以与已知的取向和/或角位移相关，并且可以将测量的排气压力与已知的排气压力进行比较以确定取向和/或角位移。在另一个实施例中，从致动器（34,36）排出的流体的流量可以从排气压力导出。然后可以使用排气流量来计算致动状态，其可以允许确定可倾斜接头（6）的角位移。相对于底部钻具组合（4）的定向和/或角位移可以分解成相对于地层（14）的倾角和方位角。

摘要： The invention provides a sealing gland capable of use in high-pressure environments and methods for the use thereof. One aspect of the invention provides a sealing gland including: a first sealing surface having a first groove and a second groove, a first O-ring received in the first groove, a second O-ring received in the second groove, and a pressure port located on the first sealing surface between the first groove and the second groove. The pressure port is configured to apply a fluid pressure intermediate to a first pressure applied to the first O-ring and a second pressure applied to the second O-ring.
