摘要
Abstract
For the new electromagnetic resistivity tool structure developed by COSL , the numerical simulation software is developed based on 3D vector finite element method . The accuracy of the algorithm is verified by comparison with the simulation results of the third-party software .On the basis of this ,researching the investigating characteristics and the influence of various environmental factors ,including the depth of the investigation ,the vertical resolution , the wellbore effect , the formation anisotropy , etc . The simulation results enhance the understanding of the ACPR detection characteristics ,and establishe a solid theoretical basis for the interpretation of logging data .By constructing the experimental platform to construct the formation model , the relative error of the instrument measurement data and the software simulation result is less than 5.0% ,which indicates the accuracy of ACPR circuit design .The comparison of the field test data shows that the phase difference resistivity of the ACPR and the dual lateral resistivity are still highly consistent in the high resistivity interval ,which shows the reliability and applicability of the ACPR instrument .关键词
