摘要:
研究了基于有限元仿真軟件COMSOL的陣列感應測井偏心響應數值計算方法。通過解決偏心模型的建立、地層大小的選取、網格剖分設計和求解器的選取等問題,高效準確地計算出陣列感應測井儀器MIT的偏心響應。均勻地層COMSOL仿真軟件計算結果與解析解的相對誤差最大為0369 796%,能夠較好地滿足計算精度,計算數據可靠有效。應用COMSOL仿真軟件對陣列感應測井儀器MIT建立偏心響應數據庫,對偏心嚴重的響應繪制圖版進行分析,可有效分析偏心對視電導率的影響。
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.
