Analyzed the gas adsorption characteristics in the experiment and the influence of injection pressures on the replacement of with CO₂, and proposed that replacement effect was better at low pore pressure. The results are as follows. Adsorption capacity of CO₂ is stronger than that of CH₄ under the same condition in the process of displacement; CH₄ volume ratio decreases with injection pressure decreasing, while CO₂ volume ratio shows the opposite trend; When the confining pressure is 8 MPa, the CH₄ output ratio reduces with linear relation and the replacement ratio of CO₂ reduces with exponential relation as injection pressure increases, and indicating that the replacement is better at low injection pressure in this displacement experimental; The replacement effect of meager lean coal sample is better than anthracite under the same conditions in this experimental., authors=WANG Jin, WANG Yanbin, FAN Jingjing, LIU Chenglong, XUE Pei, authorsList=WANG Jin, WANG Yanbin, FAN Jingjing, LIU Chenglong, XUE

articleAbstract=利用屯留矿和寺河矿圆柱体原煤试样,进行不同注入压力条件下注CO₂置换CH₄试验,研究分析了置换过程中气体的吸附特性及注入压力对CO₂置换效果的影响,提出了低孔隙压力条件时具有更好的置换效果。研究结果表明,同等条件下,置换平衡后煤体吸附CO₂气体能力远强于CH₄;煤体中CH₄体积比随注入压力的降低而减小,而CO₂体积比则呈现相反趋势;在8 MPa围压条件下,随着注入压力的升高,CH₄产出率呈线性关系降低,CO₂置换比呈指数关系减小,显示出在试验压力范围内,低压条件下的CO₂置换效果更佳;同等条件时,相对于试验中的无烟煤,贫瘦煤置换效果更好。, authors=王晋, 王延斌, 范晶晶, 刘成龙, 薛培, authorsList=王晋, 王延斌, 范晶晶, 刘成龙, 薛培,
