运用岩心观察描述、电性、生产测试及开发动态等动静态资料 ,综合分析了蒙古林砂岩油藏的沉积相 ,并在单井微相划分及各微相对应电性特征研究等的基础上 ,进行了油藏各沉积时间单元微相的划分 .分析认为 ,各微相具有不同的岩性、电性、物性、产能特征以及不同的砂体与油层发育规律 ,纵向上不同微相组合、平面上不同微相注采井组合对油田开发以及开发中后期剩余油分布具有较大的影响 ,从而明确了油藏潜力的分布与挖潜方向 .在以上研究的基础上 ,对已进入高含水开发期的蒙古林砂岩油藏施行了合理的纵、横向注采结构调整等调水增油措施 ,收到良好效果 ,确保了油田长期超开发方案指标运行
On the basis of core observation and description, electrical properties, production testing and development dynamic and other dynamic data, the sedimentary facies of the Mongolian sandstone reservoir are comprehensively analyzed. On the basis of single-well microfacies classification and the corresponding electrical characteristics of each microfacies , The division of microfacies in each depositional time of the reservoir was carried out.Analysis shows that the microfacies have different lithology, electrical property, physical property, productivity characteristics and different sand body and oil layer development law, different vertical micro-facies combination, The combination of injection and production with different micro-facies in the plane has a great influence on the development of oilfields and the distribution of remaining oil in the middle and late stages of development, so as to clarify the distribution and potential tapping potential of reservoir potential.Based on the above studies, The Mongolian sandstone reservoirs underwent a period of water and oil increase measures such as reasonable vertical and horizontal injection-production structure adjustment and received good results, ensuring long-term over-development of oilfield program indicators
