摘要
本文论述了温压下岩石孔隙度、渗透率参数测定仪器原理、仪器结构以及 各种条件实验。实验结果表明，该仪器在不同温压下，孔隙度、渗透率测量最大相 对误差分别小于０．３％和１．９％。同一压力下，随温度升高，岩石孔隙度变化呈负相 关；同一温度下，随压力的升高，岩石孔隙度变化呈负相关，而岩石的气体渗透率 与压力和温度变化不太明显。
This paper discusses the principle and structure of the instrument for measuring rock porosity and permeability under temperature and pressure, and also various conditional experiments. Large quantity of experimental results show that under different temperature- pressure the maximum relative error of this instrument are respectively less than 0.3% and 1.9%.
