摘要
由岩石高压物性实验和高温高压电性实验得知 ,岩石在高温高压条件下 ,其物性参数与电性参数都将发生较大变化。岩石孔隙度的减小量与压力有关 ,岩石受压后的渗透率除与孔隙度有关外 ,亦与所受压力大小有关。随温度的升高 ,m和n值降低 ;随压力的增大 ,m和n均增大。
From the experiment of high pressure physical property and high temperature and high pressure (HTHP) electrical property, it can be known that the physical property parameter and electrical property parameter will change under the condition of HTHP. The decrease of porosity is related to pressure;the permeability of the pressed rock has a relation not only to porosity but also to pressure;And with the rising of temperature, the magnitude of m and n will decrease, but with the rising of pressure, both m and n will increase.
