摘要
应用统计学的方法定量研究了储层组成、结构特性影响水敏性的规律。结果表明,特低渗透与高渗透储层的岩石组成、结构等特性参数与水敏性的关系有相似规律;低渗透与中渗透储层的岩石组成、结构等特性参数与水敏性的关系有相似规律。
Water sensitivity accounts for one of the major causes for formation damage. The paper applies the statistic method to study the influences of reservoir natural parameters, which include rock components, physical property, size of pore and throat, etc, on water sensitivity. Some similarities could be found between the extra-low permeable reservoir and highly permeable reservoir on the influencing tendency > and the same is true between low permeable and medium permeable reservoirs.
