选取小层砂体平均厚度、小层砂体孔隙度值、小层砂体渗透率值、小层砂体含油饱和度值、排驱压力、中值压力、分选系数这7个参数对储层进行综合评价,并最终建立了研究区储层分类评价标准; The average thickness of small sand body, the porosity value of small sand body, the permeability value of small sand body, the oil saturation value of small sand body, the displacement pressure, the median pressure and the sorting coefficient are selected for storage Layer comprehensive evaluation, and finally established the study area reservoir classification evaluation criteria;
