摘要
针对JZ25-1构造岩性分选差,部分储层富含泥质、灰质,电性特征复杂多变等特点,对适用于纯砂岩的阿尔奇公式进行改进优化。根据泥质、灰质、纯砂岩并联导电原理,建立研究区的泥质、灰质校正后的含水饱和度模型。通过多口井的实际资料处理和岩心分析数据验证,效果较好,表明改进的阿尔奇方程可用于研究区复杂岩性储层的定量评价。
JZ25-1 structure has poor lithology sorting, the partial reservoir is rich in muddy and calcareous matter, and therefore its electrical properties are complex. For this reason, the Archie formula suitable for the evaluation of pure sandstone is improved. The corrected water saturation models of the muddy and calcareous matter in the study area are established according to the parallel con- ductance principle of muddy, calcareous and pure sandstone. The application results of in several wells and core analysis data all verify that the improved Arehie equation can be used for the quantitative evaluation of complex lithologic reservoir.
