A logging tool includes a first antenna arrangement and a second antenna arrangement of the logging tool; and at least one device for maintaining the first antenna arrangement and the second antenna arrangement in proximity to a wall of the borehole.

摘要： Measurements made by a multi-component induction logging tool are corrected for tool eccentricity in a deviated borehole. The eccentricity angle is determined from single frequency skin-effect corrected data and is then used to correct multifrequency data. Multifrequency focusing is then applied to the corrected multifrequency data. An inversion is then used to recover formation resistivity and relative dip and azimuth of the borehole.

摘要： Multi-component induction measurements are made using a resistivity logging tool in an anistropic earth formation. The X- signal (quadrature) is insensitive to borehole eccentricity. A subset of the multi-component measurements are inverted to first determine horizontal resistivities. Using the determined horizontal resistivities and another subset of the multi-component measurements, the vertical resistivities are obtained. Results of using the in-phase signals are comparable to those obtained using multifrequency focusing of quadrature signals.

摘要： A misalignment angle between the transmitter (18) and receiver (19) antenna of a multicomponent induction logging tool (9) are estimated from quadrature component signals at multiple frequencies. Alternatively, measurements are inverted without using a selected cross-component measurement. A model is used to predict the value of the selected cross-component. A misalignment angle is estimated from the predicted and actual values of the selected cross component. Alternatively, using measurements made at a plurality of rotational angles, a misalignment angle between the transmitter antenna (18) and the second receiver antenna (19) is estimated.
