摘要
本文选取大庆油田萨北地区萨尔图二类油层和高台子二类油层的相同渗透率级别的天然岩心进行水驱实验,对比水驱规律,实验结果表明,水测渗透率为50×1-0 3μm2、100×1-0 3μm2、200×1-0 3μm2的天然岩心,萨尔图油层的水驱采收率均高于高台子油层,通过用水驱规律曲线对比发现,在半对数坐标系下,二类油层的水驱采收率与水油比存在较好的线性关系,这一点与一类油层相同。
In this paper,different permeability cores of class П reservoir in the north of Sa Ertu and Gao Taizi are selected to proceed water drive,the displacement law is compared,laboratory results show that the oil recovery of water drive in Sa Rrtu reservoir is higher than that of Gao Taizi reservoir which water permeability includes 50,100 and 200 millidarcy.By the comparison of regular pattern curve of water drive,it was found that in the semi-log coordinate,oil recovery of water drive and water-oil ratio presents good linear relationship,which is same to the class Ι reservoir.
