| 摘 要： | 论述了致密砂岩气藏特低渗形成的原因:即先天的沉积因素和后天的成岩作用等。得出结论:近源和远源沉积、矿物成熟度和矿物的泥化硅化、压实胶结、有无烃类饱和以及是否接触泥岩层都是影响致密砂岩气藏渗透率的因素。

| Abstract: | This paper reviews the forming reasons of extremely low permeability of tight sandstone gas reservoir,including congenital aggradation and acquired diagenesis.All factors are proximal sedimentary source and far sedimentary source,maturation of minerals,clayey and silicification of minerals,compaction and cementation,having hydrocarbon saturation or not and its contact degree with mudstone. |
