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：来自至少一个能够倾斜底部孔组件（4）的接头（6）的致动器（34,36）的排气压力可用于确定可倾斜接头（6）指向的方向（例如，取向，角度位移和/或倾斜度和方位角）。在一个实施例中，已知的排气压力可以与已知的取向和/或角位移相关联，并且可以将测量的排气压力与已知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，这可以允许确定可倾斜接头（6）的角位移。相对于底孔组件（4）的取向和/或角位移可被分解成相对于地层（14）的倾斜度和方位角。
