摘要:
研究了基于有限元仿真软件COMSOL的阵列感应测井偏心响应数值计算方法。通过解决偏心模型的建立、地层大小的选取、网格剖分设计和求解器的选取等问题,高效准确地计算出阵列感应测井仪器MIT的偏心响应。均匀地层COMSOL仿真软件计算结果与解析解的相对误差最大为0369 796%,能够较好地满足计算精度,计算数据可靠有效。应用COMSOL仿真软件对阵列感应测井仪器MIT建立偏心响应数据库,对偏心严重的响应绘制图版进行分析,可有效分析偏心对视电导率的影响。
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.
