高温下岩石渗透率变化的探究

Research on Change of Rock Permeability under High Temperature

通过研究渗透率随温度的变化情况,分析了非常温下渗透率随温度的变化特征及其影响机制,得到了如下结论:(1)在达到一定的温度门槛值之后,岩石的渗透率发生突变并急剧增加,并且这种突变具有普遍性;(2)岩石渗透率与温度的变化关系可以用指数函数表示。

By studying and analyzing the charactenstlcs and influence mecnamsm oi rOCK permeability change with high temperature ,come to the conclusions as follows： （1）after the temperature increases to initiation threshold value, the rock permeability increases suddenly and rapidly,also,this kind of change has been consistently observed; （2）the relation between rock permeability and temperature can be approximately expressed in a mathematical function.
