摘要：

松辽盆地历经燕山运动、喜山运动两期重要的构造运动。燕山期构造运动褶皱强烈,是松辽盆地北部大庆长垣大型构造油气藏形成的主要时期;喜山期构造运动尽管在松辽盆地内部表现较弱,但对盆地北部早期形成的油气藏依然具有调整、改造作用。岩石矿物有机包裹体均一化温度的测定结果,反映青山口组一段烃源岩发生过两期排烃过程,扶余、杨大城子油层经历了3期油气注入。自生伊利石的K/Ar年龄测定,表明松辽盆地大庆长垣两侧的齐家-古龙及三肇凹陷周边地区的扶余、杨大城子油层成藏时间在51～35Ma,是喜山运动期间,松辽盆地北部早期的油气藏遭到不同程度的破坏、改造形成的次生油藏。

Abstract:

Songliao basin has experienced Yanshan movement and Himalayan movement.Yanshan movement resulted in strong folding,and the large structures and oil/gas reservoirs in Daqing placanticline in northern Songliao basin have mainly been formed during this period.Himalayan movement,though being weak in Songliao basin,has adjusted and modified the early formed oil and gas pools and become a number of secondary oil and gas pools in the northern part of the basin.Homogenization temperature measurement of organic inclusion in minerals shows that there have been two periods of hydrocarbon expulsion from source rocks in the first member of Qingshankou Formation,and three periods of hydrocarbon infilling into Fuyu and Yangdachengzi reservoirs.According to authigenic illite K/Ar dating,secondary oil/gas reservoirs have been accumulated in 51-35 Ma in the above mentioned two reservoirs in the surrounding area of Qijia-Gulong and Sanzhao sags on both sides of Daqing placanticline.This indicates that during the Himalayan movement,the early formed oil and gas reservoirs in northern Songliao basin have sustained a certain alteration and then reaccumulated and become secondary oil and gas reservoirs.

Key words: Songliao basin, tectonic movement, reservoiring time, fluid inclusion, hydrocarbon accumulation
