摘　　要：ELAN_PLUS软件是从国外引进的复杂岩性测井资料处理解释软件,可以对储层进行准确合理的定量解释,但该软件未公开算法,不能进行有效的二次开发。针对这一问题,在其提出的地层是由冲洗带和原状地层组成的梯级侵入剖面等假设的基础上,建立了地层组分模型、常规测井仪器响应方程及测井最优化目标函数,通过起作用集法求得各地层组分的最优解。利用该方法对实际测井资料进行处理,与ELAN_PLUS软件处理结果及岩心分析结果基本一致,对比结果表明该方法可以满足常规测井资料处理解释需求。ELAN_Plus is a software for processing and interpreting complex lithology data imported from abroad,which can accurately and reasonably interpret reservoir quantitatively.However,this software does not disclose the algorithm and can not be effectively redeveloped.Based on the assumption that the formation is a step invasion profile composed of flushed zone and undisturbed formation,the formation component model,the response equation of conventional logging tool and the optimization objective function of logging are established.The optimal solution of each formation component is obtained by the action set method.This method is applied to processing and interpreting the actual logging data,and the results are basically consistent with that of ELAN_PLUS and core analysis.The result shows that this method can meet the needs of conventional logging data processing and interpretation.
