摘要:
缝洞型储层非均质性强烈、孔隙类型多且结构复杂,由中高孔隙度渗透率的均质砂岩实验数据建立的Archie公式失效。这类储层中,含水饱和度计算关系中的地层胶结指数和饱和度指数表现出复杂的变化特征。岩电实验观测到的地层胶结指数不仅与孔隙度相关,还出现异常大值或小值;同样,饱和度指数也表现类似特征。基于均匀分布的粒间孔基质中包含孔洞或裂缝的双孔隙储层模型,采用数学模拟方法,定量分析了孔洞型和裂缝型次生孔隙及次生孔隙的润湿性对地层胶结指数和饱和度指数的影响。明确了岩电实验中观测到的裂缝使胶结指数激剧减小,而孔洞使胶结指数增大这一结果的物理机制,有助于岩石物理学和测井处理解释相关人员对缝洞型储层含油气性评价的复杂性有一个基本的认识,也为缝洞型储层含水饱和度的准确计算奠定了理论基础。
