双河油田437断块Ⅱ1-2层系剩余油分布规律研究

油田进入高含水后期开发后,剩余油分布越来越复杂,给油田稳产和调整挖潜方向带来的难度也越来越大,因此,剩余油分布规律预测成为保证高含水期油田稳产的一项关键工作。根据双河油田437断块的构造、物性特征和注水开发现状,分析影响该断块剩余油分布的主要因素。运用数值模拟分析方法综合研究其剩余油分布规律,从而为制定油藏下一步开发方案,提高油藏挖掘潜力提供必要的依据和保证。

Study on remaining oil distribution of Ⅱ 1 -2 strata of No. 437 fault block in Shuanghe oilfield

In high water cut state,the distribution of remaining oil becomes more and more complex,resulting in more and more difficult to the maintenance,the stable production and the production adjustment.Therefore,it is significant to forecast the distribution pattern of remaining oil to ensure a stable output of oil field.In terms of the structure,the physical property the waterflooding situation of No.437 fault block in Shuanghe oilfield,key factors to affect the dis- tribution of remaining oil are analyzed.The numeral simula- tion analysis method is utilized to study the distribution pat- tern of remaining oil,which provides necessary references and assurances to formulate the next development plan and enhance the potentials of the pools.
