低渗透煤层气间歇注热实验研究

Experimental Study of Low-permeability Coal Bed by Intermittent Inject Heat

以型煤为实验样品,通过对煤样在不同有效应力、瓦斯压力条件下,进行间歇注热的解吸实验,并对注热前后的煤样进行孔隙、裂隙的微观扫描,研究温度、间歇注热对煤层气解吸量及孔隙、裂隙发育的影响。

Based on the briquette which regard as experiment samples in different effective stress, gas pressure, conducting desorption experiments of intermittent inject heat, the pore and fracture micro scanning of experiment samples round about the heat injection,in order to study the effect of temperature, intermittent inject heat act on the pore and fracture, then the desorption.
