摘要
对辽河油田面临的严峻开发形势,创新提出了利用新技术通过改变驱替类型、驱替方式、渗流方式,重新开发老油田、进一步提高老油田采收率的二次开发理念。在探索与实践中,初步形成了二次开发技术框架,建立了二次开发技术标准,针对不同类型油藏地质开发特点,形成了系列二次开发研究和配套技术。通过现场实施,取得显著成效,从根本上改善了老油田开发效果,实现了新一轮有效开发,为老油田提高采收率探索了一条新路,对老油田开发具有普遍的借鉴意义。
Some principle blocks in Liaohe oil province have been explored and developed for a long time and are facing many problems.Liaohe oilfield has proposed a concept of secondary development by using new technology and converting ways of displacement and percolation to re-develop old oilfield and further improve oil recovery factor.Through exploration and practices,the technical framework and standard for secondary development is preliminarily set up,and a series of supporting techniques has been developed for various types of reservoir geology and development features.These have been implemented in secondary development of old oilfields in Liaohe oil province and achieved remarkable efficacy.Reservoir development performance has been improved.The old oilfields in Liaohe have come to a new round of effective development,thus providing a new way and reference of improving recovery factor in old oilfields.
