摘要
根据中国陆上油田开发实际,探讨了不同油藏类型在不同开发阶段主力采油方式间的典型组合模式。针对中国石油老油田实施二次开发工程的具体情况,深入分析了不同类型油藏在二次开发阶段,二次采油和三次采油间的相互关系及其对提高采收率的贡献大小。提出了二次开发阶段应遵循的"二三结合"开发模式,二次开发系统要担负起二次采油和三次采油的双重任务。依靠技术创新和开发方式的有效转换,从而实现二次开发大幅度提高采收率的目标。
Based on the onshore oil field development in China,the article investigates the typical composite modesof oil reservoirs in different development period.Targeting at the specific performance of redevelopment of matureoilfields of CNPC,the authors analyze the interrelationship between redevelopment of mature oilfields andtertiary recovery technology deeply,and contribution to EOR respectively at the secondary development period.Itis put forward that the composite development mode of secondary and tertiary recovery technology should followthe redevelopment of mature oilfields.The system of redevelopment of mature oilfields is supposed to undertakethe double duties,including secondary development and tertiary recovery.With the technological innovations andefficient conversion of oil development modes,the goal of improving the redevelopment of mature oilfields EORsubstantially can be achieved.
