摘要
Abstract
Studied is a method for computing the eccentric response of array induction logging based on the finite element simulation software COMSOL Multiphysics. The eccentric response of array induction logging tool MIT is computed accurately and effectively through solving multiple problems, such as model building, formation limit selection, grid division design and solver selection. The maximum relative error between COMSOL simulation results and analytic solutions for uniformed formation is 0. 369 796%. It can reach required computational accuracy, and the calculated data are reliable and effective. Established is an eccentric response database for array induction logging tool MIT with application of COMSOL software. Plotting charts for badly eccentric responses are analyzed, which may help interpreting influence of eccentricity on apparent conductivity.关键词
