    摘要: An apparatus and method for estimating a parameter of interest of an earth formation involving alignment information between non-collocated oriented receivers and their corresponding non-collocated oriented transmitters. The method may include generating signal responses indicative to energy transmitted into an earth formation; estimating differences in alignment between transmitters and receivers; using the estimated differences in alignment to compensate for misalignment; and estimating a parameter of interest using the misalignment compensated signals. The misalignment estimate may include an inversion of at least one measurement from an alignment sensor. The apparatus may include a bottom hole assembly with oriented transmitters, oriented receivers, one or more alignment sensors, and at least one processor configured to compensate for misalignment using information about difference in alignment between at least one oriented transmitter and at least one oriented receiver.

    摘要: An apparatus and method for calibrating a multi-component induction logging tool. The method may include orienting a Z-transmitter coil to be substantially orthogonal to at least one Z-receiver coil, positioning an X-transmitter coil disposed on the logging tool so that the X-transmitter coil is substantially parallel to a conducting surface; encompassing the Z-transmitter coil, the X-transmitter coil, and at least one Z-receiver coil of the logging tool with at least one conducting loop of a calibrator; and calibrating the logging tool using the calibrator. The apparatus may include a calibrator configured to receive the logging tool. The Z-transmitter coil and the Z-receiver coil may be located on separate subs that are detachable from one another.
