摘　　要：依照复式含油气系统理论 ,以区域盖层为界 ,将长岭地区划分为出 3个含油气系统 :以青山口组为盖层的深部、嫩江组为盖层的中部以及以明水组为盖层的上部含油气系统。其中深部含油气系统是长岭地区重要的含油气领域 ,目前发现有东岭气藏、达字井含气构造 ,以下生上储、自生自储及上生下储式组合方式为主 ,据盆地模拟表明成藏的关键时刻是明水组末期 ( 6 5Ma) ;中部含油气系统以下生上储及自生自储式的组合方式为主 ,成藏的关键时刻是明水组末期 ( 6 5Ma)和现今 ;上部含油气系统以下生上储式组合方式为主 ,目前正处于低成熟—成熟阶段 ,成藏的关键时刻是现在。According to the theory of oil gas bearing multi system and regarding regional cap rock as the boundary,Changling area is divided into 3 oil gas bearing systems:deeper oil gas bearing system with Qingshankou formation cap rock,middle oil gas bearing system with Nenjiang formation cap rock and upper oil gas bearing system with Mingshui formation cap rock.Among them,the deeper,as an important realm of oil gas bearing in Changling area and with Dongling gas pool and Dazijing gas bearing structure discovered at present,mainly is the style of lower source upper reservoir,self source self reservoir and upper source lower reservoir,the key period of forming pools is at the end stage of Mingshui formation (65 Ma);the Middle mainly is the style of lower source upper reseroir,the key peroid of forming pools is at the end stage of Mingshui formation and present (65 Ma);the Upper,at low mature—mature stage,mainly is the style of lower source upper reservoir,the key period of forming pools is at present.
