针对采油一队复杂小断块油藏经过历年开发,已到高含水开发后期,措施优选空间逐年变小,区块的采油速度等指标逐步恶化的问题,有针对性地在不同单元进行了“低渗单元建立恢复注水关系,夯实注采单元稳产基础;加强储层性质研究改造油层、稠油单元依靠科技新工艺”等手段,在优化注采方式改善开发效果上取得了一定的效果,使得我们对复杂小断块油藏在开发管理上的有了进一步的认识,对下步提高此类油藏的开发水平制定下一步的计划。

Aiming at the problem that a group of complex small fault block reservoirs of oil recovery development over the years, has reached the late development stage of high water cut, the preferred space for measures to become smaller year by year, oil production rate of blocks and other indicators gradually deteriorated, targeted in different units “The establishment of the relationship between recovery and waterflooding of the low-permeability units and the solid foundation of the injection and production units; the improvement of the reservoir properties and the reformation of the reservoir based on the new technology of heavy oil units” have made some achievements in optimizing the injection-production methods and improving the development results , So that we have further understanding of the development and management of complex small fault block reservoirs and formulate the next plan for further development of such reservoirs.
