20世纪70年代中期曾形成了油田开发的阶段性概念和阶段划分标准,然而在很多情况下,地质条件和所采用的开发系统的巨大差异使得具体油田的开发阶段并不相同。文章以罗马什金油田为例,介绍了油田各个开发阶段的开发时间和开发特点,详细研究了开发晚期油田的储量开采问题,论述了在油田开发第四阶段的三项主要任务:依靠开采已动用储量提高原油采收率;提高难采储量的开发效果;剩余储量的开采问题。
In the mid-1970s, the staged concepts and stage classification criteria for oilfield development had been developed. However, in many cases, the vast differences between the geological conditions and the development systems employed have led to different phases of development in a particular field. Taking the Roma Shijin oil field as an example, this paper introduces the development time and development characteristics of oilfields in various development stages, studies the reserves exploitation in the late stage of oilfield development in detail, and discusses the three main tasks in the fourth stage of oilfield development: relying on mining Use reserves to improve oil recovery; improve the development of hard-to-extract reserves; the remaining reserves of the mining problem.
