摘    要:松辽盆地庆深气田深层火山岩主要岩石类型为流纹岩、熔结凝灰岩、凝灰岩、火山集块岩、安山岩、英安岩和粗面岩,以中酸性火山岩为主,其主要储气岩为流纹岩和凝灰岩,与国内其他含油气盆地的火山岩储层明显不同。其原生孔隙受岩性、岩相控制,后期的成岩改造作用,包括构造活动、风化淋滤、溶蚀作用、脱玻化作用决定了火山岩次生孔隙发育程度,尤其是溶蚀作用,它是决定原生孔隙不发育火山岩能否成为有效储层的关键因素。不同地区火山岩储层的发育状况与火山岩所处的位置有关。火山机构多沿断裂带分布,火山口附近多种岩相叠合区和近火山口爆发相和喷溢相叠合区的储层物性较好,是天然气勘探的有利目标。

关 键 词:松辽盆地  徐家围子  火山岩储层  储集性  火山岩岩相叠合

Abstract:The gas-bearing volcanic rocks of Qingshen gas field in the Songliao Basin consist of rhyolite,ignimbrite,tuff,agglomerate,andesite,dacite,trachite,most of them belong to middle-acidic volcanic,and the mainly gas reservoir rocks are rhyolite and tuff,which is different from other volcanic reservoir of oil and gas fields in China.The primary pores of the volcanic reservoir are controlled by rock types and lithofacies.Diagenesis and reformation,such as tectonic activities,weathering,dissolves,devitrificaties decide the development evaluation of the secondary pores.The developments of volcanic reservoirs in different areas associate with the location of volcanic rocks.Volcanic apparatus distribute along the fault zones.The multi-lithofacies superimposing areas around volcanic crater,and the eruption and effusion facies near volcanic crater superimposing areas have better reservoir properties,and these areas are the favorable gas exploration target.
Keywords:Songliao Basin  Xujiaweizi  volcanic reservoir  volcanic facies superimposition
