摘要： Disclosed is a method for determining calibration factors of an induction tool that includes three receiver coils, each having a distinct orientation. The method includes: placing the induction logging tool in a first position at a first height above a surface of the earth; performing a first set of measurements of conductivity using the receiver coils with the induction logging tool in the first position at the first height; placing the induction logging tool in a second position at a second height above the surface of the earth; performing a second set of measurements of conductivity using the receiver coils with the induction logging tool in the second position at the second height; and determining the calibration factors that correct conductivity measurements performed by the induction logging tool in a borehole penetrating the earth using the first and second sets of measurements.

摘要： An apparatus, method and computer-readable medium are provided for estimating a resistivity property of an earth formation. 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. The first antenna arrangement and the second antenna arrangement may be at substantially the same axial location on the logging tool. Alternately, the first antenna arrangement and the second antenna arrangement may be at different axial positions on the logging tool. Extendible arms of the logging tool are configured to extend one or more of the first antenna arrangement and the second antenna arrangement against a face of the borehole.

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.
