概述了罗马什金油田开发50多年来所取得的成就,详细介绍了该油田在开发工艺领域所解决的问题以及采用的方法。对油田开发规划的四个阶段所运用的主要原则进行了比较分析,提出前三个开发原则的不足,并在第四个开发规划中提出了相应的改进措施。为了持续提高油田可采储量,提出两种先进的可行方法:一是扩大原油储集岩的范围;二是应用三次采油乃至四次采油的先进方法持续提高原油采收率。对罗马什金油田若干年来在这两方面进行的跟踪研究做了分析,并提出:如果依靠应用提高原油采收率方法、储集岩标准值的概念以及改变与此相关的油田地质模型之后,油田预测开采量得到证实,那么罗马什金油田Д_1Д_0层的平衡储量,特别是可采储量将会增长,油田的可采储量也会因此增加,油田开发期将维持150~200年。
The achievements made over the past 50 years in the development of the Roman Shishin oilfield are summarized. The problems that the oilfield has solved in the field of development technology and the methods adopted are described in detail. The main principles used in the four phases of oilfield development planning were compared and analyzed. The deficiencies of the first three development principles were pointed out and the corresponding improvement measures were put forward in the fourth development planning. In order to continuously improve the recoverable reserves of oilfields, two advanced and feasible methods are proposed: one is to expand the scope of crude oil reservoir rock; the other is to continuously increase the oil recovery rate by advanced methods of tertiary oil recovery and even fourth oil recovery. After several years of follow-up studies on the Roman shijin oil field in these two aspects, the authors put forward that if we rely on the application of the method of enhancing oil recovery, the concept of reservoir rock standard value and the geological model of the oil field related to this change, Proved reserves of oilfields have been confirmed, so that balance reserves, especially recoverable reserves, of the Д_1Д_0 layer of the Roma Shijin oilfield will increase, and recoverable reserves of oilfields will therefore increase, and the oilfield development period will last between 150 and 200 years.
