摘　　要：喇嘛甸油藏的成藏年代学研究对于深入认识陆相含油气盆地大型油气藏成藏机理具有重要意义．采用储层自生矿物年代学分析方法，研究了松辽盆地喇嘛甸油藏成藏年代，结合埋藏史研究结果，分析了油藏形成时间与构造抬升的关系．结果表明：大庆油田北部的喇嘛甸油藏成藏年龄为65-40Ma；松辽盆地在73Ma左右和65～35Ma期间发生了2次构造抬升，受65-35Ma期间构造抬升的控制，喇嘛甸油藏在构造抬升的早期快速成藏．Analysis of chronological accumulation of Lamadian oil reservoir is of great significance in recognizing the mechanism of bigness hydrocarbon accumulation of continental hydrocarbon-bearing basin.Using the methods of the K-Ar dating of authigenic illites in oil-bearing sandstone reservoir and reconstruction of buried history,the accumulation time and its relationship to tectonic upwelling have been discovered.The data of K-Ar dating of authigenic illites in Lamadian oil-bearing sandstone reservoir indicates that the oil reservoir had been formed during 65 Ma to 40 Ma.The analysis of buried history revealed that 2 tectonic upwellings during about 73 Ma and 65-35 Ma occurred in Songliao basin,controlled by the tectonic upwelling during about 65-35 Ma,therefore,the Lamadian oil reservoir rapidly formed in the early period of tectonic upwelling.
