摘要(Abstract)：
伊利石测年法、包裹体均一温度法综合分析表明,海拉尔盆地乌尔逊凹陷油气成藏期主要分为两大阶段:第一阶段大约在120～80Ma,油气成藏时期相当于伊敏组沉积晚期,是海拉尔盆地乌尔逊凹陷最主要的成藏时期,也是海拉尔盆地一次重要的油气成藏期;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,第二阶段油气成藏时期对海拉尔盆地油气藏形成起着重要作用。
The comprehensive analysis of illite measuring age method and inclusion equal temperature method indicates,the periods of reservoir-forming of Wuerxun Sag of Hailaer Basin consist of two stages:the first stage is about 120-80 Ma,in which the reservoir was mainly formed and the late Yimin formation was deposited,which is also the important period of reservoir-forming in Hailaer Basin;the second stage is from the deposition of Qingyuangang formation up to now.Since deposition of Qingyuangang formation,the formed reservoirs have altered because of the compression-inversion near east-west direction.At the same time re-formed oil and gas was carried into reservoirs continuously.This stage plays a very important role in the reservoir- forming in Hailaer Basin.
