摘要
在对储油岩芯液体吸附特性研究的基础上 ,提出了用核磁共振弛豫方法测定岩芯“有效渗透率”的方法 ,并对实际样品进行了测定分析 ,获得了较满意的结果 .此方法测定的有效渗透率较传统方法测定的渗透率更接近于实际的储油岩层的渗透率 .有效渗透率的值可以用来进行油藏注水开发效果分析 ,研究油层剩余油分布 .
Based on a previous study on the absorption mechanisms of liquids in oil reservoir core, a method for determining the effective permeability of sandstone was developed in this study, and the results obtained appeared relatively satisfactory. The effective permeability of sandstone determined by this method was closer to the real value than that obtained by the conventional method. The value of effective permeability derived can be used for evaluating the performance/cost ratio of using the water flooding method in an oil field, and for studying the distribution of surplus oil in an oil field. It is believed that this method will find many practical applications.
