摘要
详细分析四川盆地A地区侏罗系气藏的成岩及后生作用可知:破裂及溶蚀作用对孔喉有一定的改善,而以胶结作用为主的后生作用是对孔隙结构影响最为严重的破坏性成岩后生作用。
A detailed analysis of the diagenesis and epigenesis of Jurassic gas reservoirs in area A of Sichuan Basin shows that fracture and dissolution have a certain improvement in pore throats,and the epigenesis dominated by cementation is the destructive diagenesis and epigenesis which has the most serious influence on the pore structure.
