| 摘 要： | 应用储层自生伊利石测年法、烃源岩生排烃史法和包裹体均一温度法等综合分析海拉尔盆地贝尔凹陷油气成藏期次。分析结果表明海拉尔盆地贝尔凹陷油气成藏期主要分为两个大阶段:第一阶段油气成藏时期在距今120~80 Ma,相当于伊敏组沉积时期—青元岗组沉积早期,是海拉尔盆地贝尔凹陷最主要的成藏时期,油气大规模注入储层时期应该在105~90 Ma,相当于伊敏组二、三段沉积时期,此时期为烃源岩大量生排烃时期,油气运移动力充足,有利于油气发生大规模的运移并聚集成藏;第二阶段为青元岗组沉积至今,青元岗组沉积以来,发生过近东西向的挤压反转,使已形成的油气藏重新调整,同时二次生成的油气继续注入成藏。

| Abstract: | On the basis of illite dating method,hydrocarbon generated and hydrocarbon expulsed process and homogenization temperatures of fluid inclusion,formation stages of oil-gas reservoirs in Beier depression of Hailaer basin are studied.It shows that there are two main formation stages of oil-gas reservoirs in Beier depression of Hailaer basin.The first stage is about 120-80 Ma,which is corresponding to sedimentary period of Yimin Formation-early sedimentary period of Qingyuangang Formation,which is the main form... |
