摘要
利用有效渗透率、变异系数、剩余可流动油饱和度及有效厚度等９个参数，用模糊数学方法推导出表示剩余油饱和度的隶属函数表达式，并对聚合物驱层系组合进行优化．对每个参数选取一个隶属函数和隶属度，进而得到加权隶属度值，即优先值，可用此值判断组合在一起的层系的优劣．用此方法将萨中北一、二排西部砂岩组划分为４套开发层系，并选择了７种开发方案，第一方案的层系组合，是最优的层系组合，最优值为１．９３．
The function relations denoting remaining oil saturation are deduced by means of fuzzy mathematics method as well as nine parameters such as effective permeability, variability factor and effective thickness. According to this method, the sandstone group in midwest of Saertu oilfield is divided into four devetopment series, and seven development projects are chosen, the optimal combination value in the first project's series is 1.93 and proves to be the best one.
