摘要： An apparatus and method for estimating a parameter of interest of an earth formation involving alignment information between receivers and their corresponding oriented transmitters. The method may include generating signals indicative responses 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 apparatus may include a bottom hole assembly with one or more oriented transmitters, one or more oriented receivers, one or more alignment sensors, and at least one processor configured to compensate for misalignment using information about difference in alignment between the at least one oriented transmitter and at least one oriented receiver.

摘要： Borehole images obtained with MWD measurements have a mismatch with subsequent images obtained when measurements are repeated over the same depth interval after the drillstring has been raised up. The difference is attributable to stretch of the drillstring. This can be estimated by correlating the two images. The difference can also be estimated by monitoring drilling conditions such as RPM, WOB and torque on reentry.
摘要翻译：使用MWD测量获得的钻孔图像与在钻柱升高后在相同深度间隔上重复测量时获得的后续图像不匹配。不同之处在于钻柱的拉伸。这可以通过关联两个图像来估计。还可以通过监测钻井条件（如RPM，WOB和折返转矩）来估算这个差异。
