摘　　要：方法利用产水率与含水饱和度组合参数，对稠油储层进行研究。目的划分稠油等级，优选开采方案。结果地层产水、产油率与含水、含油饱和度组合参数（ｆｏＳｏ和ｆｗＳｗ）其比值（ＦＳＫ）大于１，稠油等级高，热采效果好，产量高；等于１，稠油等级低，热采效果差，产量低；小于１，热采无效果。结论用该方法确定的稠油等级较目前采用的其它方法效果好，简便易行且应用范围较广。Methodviscous crude oil reservoir is studied by combination parameter of waterproducing rate and water saturation. PurposeTo determine viscous crude oil grade and optimize development plan. ResultThe relationship between formation water cut, oil cut and water saturation and oil saturation(shown as f o S o, f]w S w) is as follows: if the ratio ( FSK) is more than 1, the viscous crude oil is good in grade with favorable thermal recovery effect and high production. If the ratio is 1, the viscous crude oil is low in grade with poor thermal recovery effect and low production. If the ratio is less than 1, thermal recovery has no effect.ConclusionThe viscous crude oil grade decided by this method is more effective than others. It is simple and practical and has a wide range of application.
