摘要
综合运用分布函数曲线、排驱压力、测试、试油、产能和束缚水饱和度等方法,求取了高邮凹陷阜三段储层不同深度的物性下限,通过回归拟合获得了其物性下限与深度之间的函数方程,并探讨了各种方法的特点与物性下限的控制因素。结果表明:分布函数曲线法最为可靠,其他几种方法各有利弊,应将这些方法综合使用。而工区孔隙度下限主要受以原生孔隙为主的储层控制,受深度影响大,与埋深的对数呈较好的线性关系;渗透率下限主要受以次生孔隙为主的储层影响,与埋深呈指数关系,相关性相对较差。
The lower limits of physical properties at different depths of E1f3 reservoir in Gaoyou Sag were determined by comprehensive use of distribution function curve,displacement pressures,tests,well testing,capacity and irreducible water saturation,etc.And the functional equation between lower limit of physical property and depth was obtained.Characters of these used methods and control factors of lower limit of physical property were discussed.The results showed that the method of distribution function curve was most reliable,and the other methods had advantages and disadvantages respectively.The authentic lower limit of physical property should be determined by combined uses of these methods.The lower limit of porosity and logarithmic depth were preferable linear relationship,and it was controlled by primary porosity reservoir.The lower limit of permeability and depth were exponential relationship,and it was affected by induced porosity reservoir.
