摘　　要：根据物性差异,混合矿物体积模型将地下岩层简化为三部分:混合矿物骨架、泥质和孔隙空间,由此建立不同测井方法的测井响应方程及约束条件,产生一个误差目标函数,用可变误差多面体法优化计算目标函数,反演测井理论响应值,求解储层参数.经对若干井的应用,取得了满意的结果。The mixed mineral volume model simply divides ground formation into three portions: mixed mineral matrix、shale and porous space according to the petrophysical anomalies. On the basis of the model, we established the log response equations and limit conditions of different log modes, from which an error objective function is developed. By optimizing the objective function with the changeable error polyhedron method, we inversed the log theoretical response value and finally got the parameters of complex reservoir. By utilizing such an approach in a number of wells, a satisfactory result is achieved.
