砂岩在温度作用下渗透率的实验研究

The Experiment of the Rmeability Law Under Temerature Function of Sandstone

在以往实验的基础上,充分考虑岩石在温度作用下内部结构变化,选用阜新地层砂岩进行高温下的渗透率的实验研究。实验结果得砂岩的渗透率随温度增加而降低,为研究阜新地层地热开发提供理论基础。

Based on the previous experiments and fully taken account of changes in the internal structure of rock and changes of viscosity of water under the temperature the paper carries on experiments of permeability of sandstone selecting from fuxin under the high temperature. The experiment result is that the viscidity coefficient of drawing water reduces with the temperature rising, the permeability of the sandstone reduces with temperature increasing. Exploit the theoretical foundation in order to study formation geothermal development of Fuxin.
