摘要
通过岩心观察、岩屑薄片分析、ECS成分识别以及FMI岩石结构及构造解释,共识别出2大类(火山熔岩和火山碎屑岩)8种(少孔和致密流纹岩、气孔流纹岩、原地自碎角砾化熔岩、晶屑熔结凝灰岩、含角砾晶屑熔结凝灰岩、火山角砾岩、火山集块岩和沉凝灰岩)火山岩岩性。以单井岩性识别及岩相划分为基础,应用地震属性分析、波形分类等方法,建立了3大类8种亚相的岩相模式。通过对火山岩储集层的储集空间类型、孔隙结构及孔缝组合进行分析,研究了原地自碎角砾化熔岩(溢流相顶部亚相)等岩性、岩相对火山岩储集层发育的控制作用,总结了长岭气田有利储集层分布规律及对应岩性、岩相特征,为油田开发方案优化及开发层位优选提供了依据。图5表3参10
Eight types of volcanic lithologies(less-pore and tight rhyolite,stomatal rhyolite,autochthonous autobreccia lava,crystal ignimbrite,crystal ignimbrite with breccia,volcanic breccia,volcanic agglomerate and sedimentary tuff) under two categories(volcanic lava and volcanic arenite) are identified using core observation,cuttings slice analysis,ECS component identification and FMI rock texture and structural interpretation.On the basis of single-well lithologic identification and lithofacies division,the facies patterns of eight sub-facies in three categories are established by using seismic attribute analysis and wave analysis.The control of such lithology and lithofacies as autochthonous autobreccia lava(top subfacies of overflow lithofacies) on the development of the reservoirs are studied,and the distribution of favorable reservoirs in Changling gasfield and the corresponding features of lithology and lithofacies are summarized,through the analysis of reservoir space type,pore structure and pore-fracture assemblage in volcanic reservoirs,which provids a basis for field development planning and production horizon optimizations.
