摘要
同一样品在不同干燥温度处理后的对比实验显示,在110℃干燥条件下页岩的失水率高于60℃的失水率;而110℃干燥的页岩样品甲烷吸附量也显著高于60℃干燥条件下的甲烷吸附量。可见,干燥温度显然是影响页岩甲烷吸附的一个重要因素。尽管页岩的甲烷吸附量受干燥温度的影响,但同一个样品的甲烷吸附曲线形态基本相似,显示干燥温度主要影响到页岩吸附量,但并不影响页岩吸附机理,这表明,较高干燥温度下由于水分的驱除增加了页岩吸附的孔隙。
The contrast experiment for the same shale sample after different drying temperature processing shows that the water loss rate of shale sample at 110 drying temperature is higher than that at 60 , and the methane adsorption capacity at 110 is also much higher than that at 60 . As a result, the drying temperature is obviously a very important factor influencing the shale methane adsorption capacity. Even so, the study indicates that the drying temperature mainly affects the shale adsorption capacity, but does not influence the mechanism of shale adsorption for the same shale sample, which suggests that higher drying temperature can remove the moisture in shale away and increase the porosity adsorpted in shale.
