惠民凹陷江家店地区沙三下亚段储集层评价

Reservoir evaluation for Sha 3 lower subinterval in Jiangjiadian area of Huimin sag

该文以岩心分析、录井、测井资料为基础,深入研究了江家店地区沙三下亚段储集层的宏观展布特征和微观特征,详细分析了沉积微相、砂岩粒度、成岩作用对储集层物性的影响,并总结出成岩过程中尤以压实作用、碳酸盐含量及自生粘土矿物类型和含量对储集层物性的影响最为明显,据此对研究区储集层进行了区带划分。对指导该区勘探与开发具有重要作用。

Based on core analysis, mud logging and well logging data, the paper deeply studied the macroexpanded features and microfeatures of Sha 3 lower subinterval reservoir in Jiangjiadian area, made a detail analysis of the influence of sedimentary microfacies, sandstone grain size and diagenesis on reservoir physical property, and summarized that during diagenetic stage, compaction,carbonate content, authigenic clay mineral type and content exerted the most obvious influence on it, and based on this, the regional division was made to the studied reservoirs in the area. The evaluation and study have important functions in guiding the exploration and development of the area.
