目前,我国东部大多数油田已进入中后期开采,油田综合含水率普遍升高,开发难度逐渐加大。如何提高其开发效果,剩余油分布规律研究就显得尤为重要。通过剩余油规律研究,可以为油田开发方案的调整提供可靠的依据。剩余油饱和度研究方法 At present, most of the eastern part of China’s oilfield has entered the mid-late mining, oilfield water cut generally increased, the difficulty of developing gradually increased. How to improve its development effect, the study of remaining oil distribution is particularly important. Through the study of remaining oil law, it can provide a reliable basis for the adjustment of oilfield development plan. Remaining oil saturation research methods
