Abstract: To simplify the calculation of the logging response, a fast approach
for simulating the cylindrical electrode only with a point source is presented
in this paper. This approach transforms the problem with hollow cylindrical
electrodes to that with point sources, which does not only simplify the
calculation, but also makes the numerical mode-matching (NMM) method can be
employed directly in the calculation. The NMM method is an efficient
half-numerical and half-analytical method. By using the approach and the NMM
method, a high-efficiency code has been developed and valified. The
characteristics between responses and parameters are analyzed, which is crucial
to the inversion problem of logging and useful for logging engineers.
