摘要
在分析岩石电性影响因素的基础上,提出了将正交分析法用于判别岩石电性影响因素的敏感性,以正交矩阵设计来分析岩石电性影响因素的水平组合,用方差分析法和趋势分析法对岩石电性影响因素的敏感性进行量化评价,从而区分影响岩石电性的主要因素和次要因素。对选取的岩心样品进行岩石电性数值模拟,结果表明,岩石电性对不同影响因素的敏感性不同,敏感性分析结果符合岩石电性数值模拟结果。
Based on the analysis of influencing factors of rock electrical properties, this paper proposes using orthogonal analysis to identify sensitivities of the influencing factors, using orthogonal matrix design to analyze horizontal associations of the influencing factors, and using variance component and trend analysis approaches to quantitatively evaluate the sensitivities by which dominant and secondary factors can be distinguished. Case study from selected core samples shows that rock electrical properties exhibit different sensitivities to different influencing factors, and the sensitivity analysis result is in accordance with that of the numerical simulation of rock electrical properties.
