摘　　要：目的探究大牛地气田盒3段有利储层的控制因素及展布特征。方法通过数理统计、回归分析方法,结合薄片分析、粒度分析和物性分析等资料进行研究。结果粒度和碎屑成分是控制大牛地气田下石盒子组盒3段储层物性优劣的主要因素,粗粒且富含石英砂岩的储层物性明显较好。利用分析测试资料和测井数据,从粒度和成分入手,实现了储层的测井定量解释。结论研究区西南部的DK26-DK2井区粗粒富石英砂岩分布广且厚度大,是有利储层发育区。Aim To better understand controlling factors and distribution for reservoirs in H 3 member ot Daniudi Gas Field. Methods Using data of thin-section analysis, particle size analyses, and property analysis, methematical statistics method and regression method were employed. Results Grain size and composition are the key facors in controlling the physical characteristic of reservoirs, The coarse-grained quartz-rich sandstone have a better physical properties; According to grain size and composition, lithofacies are interpreted by wireline data combination with a large number of experimental data such as the thin-section analysis and particle size analyses. Based on this, lithofacies isopach maps was constracted. Conclusion Analysis suggests that DK16-DK2 well zone is favorable exploration areas.
