濮城油田开发后期剩余油分布特征及挖潜实践

Remaining Oil Distribution Features and Exploration Practice in Later Period of Pucheng Oil-field Development

综合应用地质、测井、试验测试及油水井动态数据等资料,按照系统工程的原则,从油藏描述着手弄清沉积相与剩余油分布入手,建立包括油藏地质分析——油藏工程研究——油藏数值模拟——水驱历史拟合——油藏精细综合描述等在内的配套研究技术。该研究成果的实施可以提高东沙二上1油藏水驱动用程度,使油藏的采收率得到进一步提高。

Combined with information of geology,logging,test and oil-water dynamic data and according to system engineering principle,research techniques including oil reservoir geological analysis-reservoir engineering research-oil reservoir data simulation-history match of water flooding-fine oil reservoir description are set up from reservoir description,sedimentary facies and distribution of remaining oil.The implementation of study can improve the water driving in Upper Sa Er reservoir and increase the level of reservoir recovery.
