摘　　要：本文在室内试验的基础之上,分别研究了温度和围压的变化对岩石电性的影响,进而得出温度对岩石电阻率的影响是随着温度的增加,岩石的电阻率下降,同时还得出围压对电阻率的影响较为明显,基本上是电阻率随着围压的增加而增加。This paper based on the indoor test, studied the changes of temperature and confining pros sure on core electrical properties and the effect of temperature on resistivity of core are obtained with the increase of temperature, is the effect of the resistivity of the rock down, also concluded that more obvious the influence of confining pressure on the resistivity, is basically the resistivity increases with the increase of confining pressure.

关 键 词：温度 围压 地层水矿化度 电阻率 实验研究
