摘　　要：松辽盆地不同埋深的青一段泥岩,有机质在成烃演化过程中有两个成烃高峰,与之对应有两个主要排烃深度段。青一段泥岩的有利排烃期是松辽盆地发育稳定期——第三系的沉积时期。第三纪末,青一段泥岩的两个主要排烃深度在平面上所确定的排烃范围,对松辽盆地东部扶余、杨大城子油层的油气藏、西部的青山口组泥岩裂缝油气藏的形成起着重要的控制作用。<ABSTRACT> There are two hydrocarbon peaks for organic matter during hydro carbon generation evolution of shale in Qing No.I Member of different burried debths in Songliao Basin.Two depth intervals of hydrocarbon expelling respond 1o these peaks.The favorable hydrocarbon expelling period of Shale in Qing No.I Member was the stable development period of Songliao Basin Tertiary dcpo- sitional period. At the end of the Tertiary system, two main hydrocarbon expe- lling depths in shale of Qing No.1 Member which determined horizontally the hydrocarbon expelling range playe an important controlling role for oil & gas pools generating in Fuyu, Yangdachengzi leservoirs in the cast of Songliao basin and fractured oil & gas pools of Qingshankou formation in the west of Songliao basin.
