Abstract: The finite element numerical simulation method and parameter sensitivity function were used to simulate the response characteristics of toroidal coil excitation LWD laterolog instrument in anisotropic formation and deviated boreholes，the sensitivity of the instrument to the formation thickness/surrounding rock，anisotropy and well deviation angle were analyzed，and based on forward modeling results segment fitting，a calculation method for rapid correction of well deviation/anisotropy was proposed for different well deviation angles. The results show that：（1）When the thickness of the target layer is less than 0.5 m，the instrument response is seriously affected by the surrounding rocks. When the thickness is 0.5-5.0 m，the instrument response is affected by both the surrounding rock and anisotropy. When the thickness is greater than 5.0 m，the influence of anisotropy on the instrument response is dominant.（2）When the well deviation angle is less than 30 °，the logging response is less affected by the anisotropy coefficient，and the maximum difference of apparent resistivity is 2.5 Ω·m. When the well deviation angle is greater than 30 °，the instrument response is seriously affected by anisotropy and cannot reflect the horizontal resistivity of the formation.（3）This method has better correction effects in conductive formation and resistive formation with larger thickness.

Key words: deviated boreholes, anisotropy, LWD laterolog, investigation depth, resolution, sensitivity, finite element numerical simulation
