【摘要】 通过对松辽盆地昌德气田13口井的岩心观察、薄片鉴定、单井分析、平面展布等分析认为:营城组一段储集岩以火山岩、沉积岩2类岩石为主,其中火山岩以凝灰岩、火山角砾岩、流纹岩为主,沉积岩以砂砾岩和泥岩为主,有效储集岩主要为凝灰岩、流纹岩及砂砾岩;火山岩相以爆发相的热碎屑流亚相和热基浪亚相为主,沉积岩相以浅湖亚相、扇三角洲平原亚相及扇三角洲前缘亚相为主,储集岩相主要为爆发相的热碎屑流亚相、喷溢相的上部亚相和扇三角洲相的扇三角洲平原亚相;营城组一段有3个主要的有利目标区。更多还原

【Abstract】 The conducted analyses of the core observation,thin section identification,individual well,planar distribution and so on for 13 wells in Changde Gasfield of Songliao Basin show that two kinds of rocks including volcanic and sedimentary rocks are dominant in Member 1 reservoir of Yingcheng Formation,among them,the former is mainly composed of tuff,volcanic breccia and rhyolite;the latter is generally made of glutinite and mud stone,the effective reservoir rocks include tuff,rhyolite and glutinite;the volcanic facies includes pyroclastic flow subfacies and base surge subfacies of the eruptive facies,the sedimentary facies are mainly composed of shallow lake,fan delta plain and fan delta front subfacieses,the reservoir facieses are mainly pyroclastic flow subfacies of the eruptive facies,upper subfacies of the eruptive and overflow facieses,and fan delta plain subfacies of the fan deltaic facies;there are 3 principal favorable areas in Member 1 of Yingcheng Formation.更多还原
