摘要:
静态建模过程中饱和度模型的准确性对于油藏合理开发,储量计算有着重要意义。对于非均质性较强的储层,单一岩石类型和单一的K-φ难以准确描述储层物性的变化,也无法准确的计算储层含水饱和度。针对非均质性较强的碳酸岩油藏,通过岩石类型划分,并结合实验室毛管力数据逐类进行处理,进而确定出每类岩石类型的饱和度模型。基于此建立的饱和度模型能够准确的反应地下流体的真实流动状况和流体分布特征。通过与常规测井结果进行对比,计算结果准确可靠,能够较好的反应储层的流体分布特征。这种方法对于非均质较强的储层尤为适用。
Abstract:
Water saturation is an important parameter for building up a static model,which is the base of STOOIP calculation.Generally,single rock type and K-φ relationship can not be used to describe the flow characteristics of liquid due to not considering the impact of formation heterogeneity,especially in carbonate reservoir.Aiming at the pore type of carbonate reservoir with serious heterogeneity,an advanced method is proposed to characterize formation according to rock type.Meanwhile,based on the results of capillary pressure data for each rock type,several saturation height functions are introduced for saturation initialization.The established saturation model through this method can reveal actual flow characteristics of liquid under reservoir conditions.This method showed an excellent agreement with log interpretation after being compared with log saturation.For heterogeneous reservoirs,this method is highly suggested on building-up the saturation model.
