鄯善油田三间房油藏开发技术及效果

THE DEVELOPING TECHNOLOGY AND RESULTS FOR SANJIANFANG RESERVOIR OF SHANSHAN OIL FIELD

针对低孔特低渗油田,在开发过程中调整挖潜难度较大,暴露出不同于中高渗油田的开发特点,为寻求处理好各种矛盾的政策界限和技术途径,达到改善低渗油田开发效果和提高经济效益的双重目的。本文以鄯善油田三间房油藏为例,根据其主要开发特点及规律,总结了油井整体压裂、强化注采系统、分层注水、开发层系调整等所做的工作,评价了所取得的效果,对低孔特低渗油田合理高效开发具有参考和借鉴价值。

It is more difficult to adjust and develop potential process for low porosity and lowest permeability oil field.It's developing feature is obvious different from medium and high permeability oil field.In order to find the way to deal with various contradictions of strategy limit and technology way and to attain the purposes of improving low permeability oil field development result and increase economic profit,this paper presents methods of oil well integral fracturing, intensified flooding and recovery system,separate zone waterflooding and developing series of strata,evaluates attained results base on the main developing character and law of Sanjianfang reservoir in Shanshan Oil Field.It has reference to reasonable and high effective development for low porosity and lowest permeability oil field.
