摘要： An acoustic logging while drilling tool includes an acoustic transmitter and a linear array of acoustic receivers. At least one of the transmitter and the linear array of receivers is deployed on a blade having an outer diameter greater than that of the tool body. In preferred embodiments the transmitter and linear array are each deployed on a distinct blade. Deployment of the transmitter and/or the receivers on a blade reduces the standoff distance to the borehole wall which tends to improve the signal strength of received guided waves without an increase in transmitter power or receiver sensitivity.

摘要： A method for correcting subterranean resistivity measurements to account for tool bending includes processing at least one coupling component and at least one cross-coupling component in combination with a tool bending angle. Such processing may, for example, remove one or more coupling components from a cross-coupling component. Removal of the coupling component(s) tends to increase the sensitivity of directional resistivity measurements to remote boundaries.

摘要： A transmitter on a bottomhole assembly (BHA) is used for generating a transient electromagnetic signal in an earth formation. A pair of receivers on the BHA receive signals that are indicative of formation resistivity and distances to bed boundaries. A time dependent calibration factor or a time-independent calibration factor may be used to combine the two received signals and estimate the distance to bed boundaries that are unaffected by the drill conductive body. Further improvement can be obtained by using copper shielding.

摘要： Methods for making calibrated microresistivity logging measurements in nonconductive drilling fluid are disclosed. A calibrated measurement parameter (e.g., a calibrated electrical impedance or a calibrated potential difference) is obtained and further utilized to compute a formation resistivity. The methods tend to be particularly well suited for drilling applications in which the borehole environment is highly resistive (i.e., boreholes in which both the drilling fluid and the formation have a high resistivity).

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.
