摘　　要：致密砂岩气是一种重要的非常规天然气资源,并且在我国其储量占全国天然气总储量的比例较大。系统的研究致密砂岩气藏的成藏机制有助于划分气藏类型,确定勘探方向,提高天然气产量。本文通过大量的文献调研,对比分析不同致密砂岩气藏在成藏过程中天然气的运移模式,根据气体运移动力的种类,提出了"活塞充注型致密砂岩气藏"、"混合驱替型致密砂岩气藏"及"置换聚拢型致密砂岩气藏"三种成藏类型,并阐述其地质特征。The tight sandstone gas is an important unconventional natural gas resource, and its reserves accounts for a larger proportion in China＆#39;s reserves. Research on forming mechanism of tight sandstone gas reservoir can helps us to divide the type of gas reservoir, determine the exploration direction and increase the output of natural gas. ＆quot;Tight sandstone gas reservoir of piston filling”, ＆quot; tight sandstone gas reservoir of hybrid displacement model ＆quot; and ＆quot; tight sandstone gas reservoirs of replacement and gathering type.” of three reservoir types are put forward through a large amount of literature research, comparative analysis on the migration mode into natural gas reservoir in the process of tight sandstone gas reservoir, according to the types of gas migration force, and its geological characteristics are explained.
