岩石扩散系数研究方法

The Research Method on Diffusion Coefflcent of Rock

摘要: 在深入分析岩石扩散系数影响因素的基础上,提出了实测岩石扩散系数的温度校正公式。根据岩石扩散系数与其孔隙中值半径之间的变化关系,建立了一套研究岩石扩散系数的方法。将其应用于松辽盆地三肇地区青山口组泥岩盖层的研究,其结果较客观地反映了该区青山口组泥岩盖层扩散系数的变化规律。本方法实用性较强。

Abstract: According to the relation between the diffusion coefficent and pore median radius of rock, this paper established method of researching diffusion coefficent of rock, and applied it to study of mudstone caprock of Qingsankou formation in Sanzhao region of Songlao basin. The results objectively reflect the variation law of diffusion coefficient of mudstone caprock.
