页岩气吸附作用及影响因素研究进展

Research of shale gas adsorption and its factors

美国页岩气成功开发,改变了世界能源格局,同时也掀起了页岩气研究热潮。页岩气主要有游离气、吸附气、溶解气三种类型。吸附气占据了页岩气产出较大的比例,研究页岩气吸附作用对于页岩气评价、开发都具有重要意义。本次论文,主要论述吸附作用,并探讨页岩气吸附影响因素的研究进展,因素主要包括:温度和压力、粘土矿物、TOC、成熟度(Ro)、水介质等。

The successful development of US shale gas has not only changed the pattern of world energy,but also raised a research boom of shale gas. There are three types of shale gas including free gas,adsored gas,dissolved gas. Adsorbed gas occupies a large proportion of total shale gas output,so the studies of shale gas adsorption is very important for shale gas evaluation and development. This paper focuses on the shale gas adsorption,and explores the progress of studies of shale gas adsorption factors including: temperature and pressure,clay minerals,TOC,maturity( Ro),aqueous medium Quality,etc.
