大庆油田聚合物驱后微观剩余油分布规律分析

Distribution Rule Analysis of Microscopic Remaining Oil After Polymer Flooding for Daqing Oil Field

油田开采一直是我国重要的资源开发形式之一,近几年随着科技水平的进步,人们对油田开采的研究越来越深入,逐渐分析油田分布规律,促进我国油田经济进一步发展。在油田开发研究过程中聚合物驱后分析微观剩余油的分布规律对剩余油的预测、挖潜,提升采油效率等具有最大的意义。通过对大庆油田不同水洗程度样微观剩余油分布规律研究,分析了大庆油田微观剩余油的饱和度值,并以此确定微观剩余油的分布及降低程度。

Oilfield exploitation has always been one of the important forms of resource development in our country. Recently, with the progress of science and technology, the study of oil field exploitation becomes more and more intensive, and analysis of oilfield distribution is taken gradually to promote the further development of oilfields economy in China.In the process of oilfield development and research, after polymer flooding, takes analysis of the biggest significance of the distribution rule of microscopic remaining oil on the prediction, potential tapping and promotion of oilproductionefficiency of remaining oil. By taking research on the distribution rule of microscopic remaining oil of Daqing oil field in different degree of wateroutdegree samples,it takes analysis of the saturation value of microscopic remaining oil of Daqing oilfield, based on which, to determine the distribution and decreased degree of microscopic remaining oil.
