摘　　要：页岩气的赋存形式造成了页岩气藏开采周期较长,需要采用激励方法来促进页岩气的解吸,而超声波激励措施为促进页岩气的解吸提供了新的思路。为了研究超声波激励环境下页岩气的解吸规律,设计了一种超声波激励环境下页岩气解吸的实验装置,包括气源系统、超声波发生系统、吸附/解吸系统、回压系统、恒温箱系统及数据采集系统等。该装置可为研究不同激励因素对页岩吸附气解吸的影响提供实验条件,并优选出最佳的超声激励参数,以达到最大的激励效率,为促进页岩气加快解吸提供实验依据。Due to the occurrence of shale gas,the production cycle of shale gas reservoir is long.So it is necessary to adopt incentive method to promote the desorption of shale gas.Ultrasonic incentive measures provide a new way to promote the desorption of shale gas.In order to investigate the desorption law of shale gas under ultrasonic excitation,an experimental device for shale gas desorption under ultrasonic excitation is designed,including gas source system,ultrasonic generation system,adsorption/desorption system,back pressure system,incubator system and data acquisition system.The device can provide experimental conditions for studying the influence of different excitation factors on the desorption of shale adsorption gas.The best ultrasonic excitation parameters,were optimized for the maximum excitation efficiency,which provides experimental basis for enhancing desorption of shale gas.
