摘要
针对河 68断块复杂的构造、储层、多种油藏类型并存的特点 ,应用了精细三维地震、储层预测、隐蔽油藏描述、油藏数值模拟、开发测井等技术手段 .在找准问题及查清剩余油潜力的基础上 ,重塑注采井网 ,配套运用工艺技术 ,使断块预测采收率由治理前的 32 .4%提高到 45 .3% .
Because of the complicated structure and more types of reservoirs of He68 fault block, fine 3D seismic data, reservoir prediction, subtle reservoir description, reservoir numerical simulation and development logging are used in the study of remaining oil distribution. According to the results of the study, injection and production well pattern is rebuilt, and some matching technologies are applied, which enhances the recovery factor from 32.4% to 45.3%. The results of the study can be used for reference to the development of similar high water cut complicated fault blocks.
