In order to study the petrophysical properties of mud-invaded formation in deviated well, a generalized curvilinear coordinate system is used to simulate the characteristics of mud invasion, and then the array laterolog response during mud invasion is researched. In this paper, a four-parameter inversion of array laterolog based on Marquardt method is adopted to effectively recover the invasion profile and then obtain the original formation resistivity in deviated well.
