针对大港枣西地区孔店组储层特点,选择反映储层宏观和微观特征参数,在建立储层评价标准基础上,应用模糊理论分析方法、对储层进行多因素综合分类评价,克服了储层评价过程中人为因素影响。研究区内储油层为湖底扇砂体和滩坝砂体,小层评价结果表明,各类储层与沉积微相关系十分密切,浊积水道和滩坝主体是区内最好储层。经储层综合评价,揭示出各类储层分布规律,为下一步油田编制开发方案,合理划分开发层系奠定可靠地质基础。
According to the reservoir characteristics of Kongdian Formation in Zaoxi area of Dagang, the reservoir macro and micro characteristics parameters are selected to reflect. Based on the establishment of reservoir evaluation criteria, the fuzzy theory analysis method is applied to comprehensively evaluate and classify the reservoir. Human factors influence the evaluation process. The reservoirs in the study area are sublacustrine fan bodies and beach bar sand bodies. The evaluation results of the small reservoirs show that the relationships between all kinds of reservoirs and sedimentary microfacies are very close, and the turbid water channel and beach dam bodies are the best reservoirs in the area. The comprehensive evaluation of the reservoir reveals the distribution of various types of reservoirs and establishes a reliable geological foundation for the next step in the preparation and development of oilfields and the rational division of development strata.
