| 英文摘要 | The resistivity logging through casing is that the potential distribution on the metal casing is measured to realize the measurement of formation resistivity. For this method, this study derived the differential equations of Jacobi matrix from the transmission line equation and its boundary conditions for a multi-layered formation, which are the derivative equations of the potential and current with respect to the transverse resistance of formation. With the differential equations we have given the analytic formula of the Jacobi matrix and realized the inversion of formation resistivity (Marquardt inversion method). With computing examples, the characteristics of Jacobi matrix were discussed, and the fast computing speed was obtained, in which the results of inverse are in excellent agreement with the model of formation. The realization of formation resistivity inversion and its fast computation of Jacobi matrix provide a theoretical basis and a fast inversion algorithm for the further development of the resistivity logging and data processing. |
