Abstract

Abstract: The indoor experiments on cyclic water flooding were made to research the oil expelling and displacement mechanism for increasing oil recovery by using long core model.The main factors affecting the effect of water flooding were revealed and analyzed.The opportunity for implementing cyclic water flooding and the guiding ideologies for optimizing the cyclic water flooding parameters for various petroleum pools were proposed.It is necessary to make fluctuation of formation pressure,bring the pressure of overlying formation and the elastic oil drainage of formation and fluid into play and enhance the action intension of the exchange of fluid between formations in the process of pressure field change for increasing the oil recovery ratio by cyclic water flooding.

Key words: cyclic water flooding, simulation rest, recovery ratio, displacement mechanism, water-driving effect, affecting factors

摘要： 为了认识周期注水改善水驱效果的机理,利用长岩心模型进行了周期注水室内实验研究,模拟了不同开发阶段、不同地层参数及不同注水方式下周期注水的采油过程,深入研究了不同孔隙结构类型储层实施周期注水改善水驱效果的机理,明确提出了周期注水的有利时机和影响因素。研究结果表明,促进地层压力波动,发挥上覆地层压力作用及地层和流体的弹性排油作用,同时增强压力场变化过程中流体层间交换的作用强度,这些是周期注水提高原油采收率的重要条件。
