利用产出剖面测井确定剩余油饱和度

Determining Production Layer Remaining Oil Saturation by Production Profile Data

提出利用产出剖面资料确定剩余油饱和度方法。根据产出剖面测井资料与岩心实验分析资料建立了产水率与储层供液半径内综合含油饱和度的关系,并将其适用条件推广到缺少取心资料的储层。以轮南油田为实例,介绍各参数求取方法,计算剩余油饱和度与测试资料确定的饱和度基本一致,为油田确定剩余油饱和度提供了一种新的可行方法。

Presented is a method of calculating remaining oil saturation by water ratio through production profile and core experiment data.The oil saturation reflects the integrated oil saturation of reservoir in hydraulic radius.The method is used in the applicable reservoir lack of coring data reservoirs.Taken Lunnan oilfield as example,the parameters of the model are introduced in detail.The last results are consistent with the actual logging data.It provides a new feasible method to determe residual oil saturation for oil field development.
