通过数值建模研究瞬时吸附模型与时间依赖模型对页岩气产量的影响，详细的分析了2种吸附-解吸模式的理论模型.通过 ECIPSE 进行了多重网格的建模，分别采用瞬时吸附、0.1、1、10、100 d 几种情况进行了研究，结果表明随着吸附-解吸时间的增加页岩气产量降低.针对近年提出的通过注 CO2提高页岩气产量的问题，进行了模拟研究显示 CO2注入到储层中后吸附到基质中被稳定的封存在页岩气储层中并且提高了页岩气的日产气量，从理论上验证了该增产方式的可行性.

Impact of transient adsorption model and time dependent adsorption model in shale gas production is investigated.The two theoretical models of adsorption-desorption are analyzed in detail.Multiple grid models are built by ECLIPSE,different conditions,such as transient and time dependent adsorption (0, 0.1,1,10,100 d),are studied.The modeling shows that with increased adsorption-desorption,time shale gas production is reduced.For CO2 enhanced gas recovery,the process of CO2 injection into reservoir is simulated. It illustrates that CO2 is absorbed by the substrate and this enhances gas recovery.It is clearly shown that CO2 is stably stored in the reservoir,therefore feasibility of the idea is verified.
