Abstract

Many factors may affect array induction log, including skin effect. In this paper, according to relative formula deduced, a correction method of skin effect based on multi-frequency measurement signals is proposed using only the real component. This paper gives apparent conductivities that are from first order derivative correction and second order derivative correction by Chebyshev polynomial fitting method. Compared with measured data calculation, it showed that the correction results from the method above were in good agreement with the data from Express software.
