基于等效岩石组分理论的饱和度指数影响因素
Keywords: 孔隙结构,非阿尔奇特性,等效岩石组分理论,饱和度指数,主控因素
Abstract:
?岩石的非阿尔奇特性主要受到孔隙结构、流体分布状态、岩石骨架附加导电、润湿性、临界饱和度等的综合影响。本文应用等效岩石组分模型进行了导电模拟,引入了孔隙结构效率、饱和度因子、饱和度指数、临界饱和度等参数,综合分析了各参数对饱和度指数的影响。研究表明:临界饱和度和第一饱和度因子对饱和度指数的影响最大,第二饱和度因子的影响次之,孔隙结构效率的影响最小,表现为:饱和度指数随着临界饱和度和第一饱和度因子的增大而增大,随着孔隙结构效率和第二饱和度因子的增大而减小。文中对中国东部g油田的岩心进行了实验分析,低孔低渗、中孔低渗、高孔低渗岩心的实验测量结果表明,在岩心孔隙度范围为15.2%~20.8%时,利用等效岩石组分模型拟合的含水饱和度—电阻率指数曲线的相关系数(0.93~0.97)较传统的阿尔奇模型拟合的相关系数(0.76~0.84)大。因此应用等效岩石组分理论能更加精确地描述岩石的非阿尔奇特性,从而明显提高饱和度计算的精度。
