摘要:

碳酸盐岩储集层饱和度的计算一直是测井界亟待解决的难题,它直接关系到储层流体性质、储量规模等方面的评价.为了认识目前碳酸盐岩测井饱和度解释模型的研究现状,在参阅国内外相关文献的基础上,将现今针对碳酸盐岩储集层的含水饱和度模型分为六类:基于经典阿尔奇公式的经验性扩展、基于孔隙类型的多重孔隙结构的饱和度模型、基于孔隙尺寸的多重孔隙结构的饱和度模型、基于岩石导电效率理论的饱和度模型、基于网络导电理论的饱和度模型和基于J函数的饱和度模型.这些饱和度解释模型在应用时均存在潜在的假设和使用条件,因此为了能够建立出更加符合地质情况的饱和度解释模型,今后还需从理论数值模拟、导电机理、岩石物理实验等方面深入研究,而基于数字岩芯的孔隙网络导电规律研究是重要的研究方向.

Abstract:

The calculation of saturation for carbonate reservoir has always been an imperative problem to be solved. It directly affects the evaluation of fluid properties,reserves scale and other aspects. In order to understand the research situation of saturation interpretation models for carbonate reservoir,this paper summarizes the current saturation interpretation models. The saturation interpretation models are divided into six types:Archie and its extended empirical saturation models,saturation models of multiple pore structure based on different pore types,saturation models of multiple pore structure based on different pore sizes,saturation models based on rock conductive efficiency theory,saturation models based on network conductive theory and saturation models based on J function. Those saturation interpretation models have potentially assumptions and conditions when using. In order to build saturation interpretation models in line with the geological conditions,we suggest that numerical simulation,rock conductive mechanism and petrophysics experiments are need further researched,and the research of pore network conductive rule based on digital core is an important research direction.
