摘要
海拉尔盆地苏德尔特油田是一个高产富含油构造带，主力含油层段兴安岭群分为4个岩性段（油组）。从砂岩岩性、成岩作用、孔隙结构特征等方面对海拉尔盆地苏德尔特油田兴安岭油层进行了分析。认为该区凝灰岩岩屑在兴安岭油层4个油组中普遍存在，属于火山碎屑沉积岩储层；主要成岩作用为压实作用、胶结作用和重结晶作用，交代作用和蚀变作用不明显；孔隙类型主要为原生粒间孔；4个油组中都有凝灰岩岩屑存在，其中Ⅰ油组孔隙度和渗透率最好，Ⅲ油组孔渗较好，Ⅱ油组、Ⅳ油组物性最差。
Suderte Oilfield in Hailer Basin is a high-production and highly oil-enriched structural belt. Its main oil layer-Xing＇ anling Group can be divided into four lithologieal intervals （ oil layer group ）. The oil layer is analyzed from the viewpoints of the sandstone lithology, diagenesis the characteristics of pore structures and so on. The studies show that the tuffaceous debris is widely distributed in above four oil layer groups, belonging to pyroelastie deposit ; the main diageneses are compaction, cementation and recrystallization, the else are metasomatism and alteration; the pore type is mainly primary intergranular pore; there is tuffaceous debris in four oil layer groups, among them the porosity and permeability in Group are the best, the next is Group Ⅲ, the worst is Group Ⅱ and Ⅳ.
