用岩石导电效率理论来说明低孔渗储层孔隙结构对m指数的影响

通过对库车地区储层孔隙结构的研究,发现在低孔渗储层条件下,储层孔隙结构比中高孔渗储层复杂很多,阿尔奇公式中的m指数不能简单的当作常数,随着孔隙结构的变化反应十分灵敏。本文从岩石导电效率理论来分析了m指数随孔隙结构的变化特征。

Through the study of the pore structure reservoir of Kuche area, it is found that under the condition of the low porosity and low permeability reservoir, the pore structure more complex than the medium or higher porosity, the m index number can＇t be treated as a constant, but much sensitive along with pore structure＇s change. The text analyzed how about the m index number change with pore structure based on the rock electrical efficiency theory.
