摘　　要：为了搞清松辽盆地构造形成与油气藏形成的关系,利用差异压实构造和反转构造理论,从构造隆起的基底凸起、构造挤压和差异压实3个主要影响因素出发,对松辽盆地6个构造的影响因素及每种因素的影响程度进行分析,研究构造与油气成藏的关系。研究结果表明:松辽盆地大部分正向构造基本都是砂岩发育区,差异压实作用形成雏形后,再经构造反转使构造的隆起幅度加大定型,反转构造具有东强西弱的特点;构造隆起幅度越大,越有利油气藏形成,构造运动趋缓时就是油气藏定型时期;朝阳沟—长春岭背斜地区油源来自三肇凹陷;古龙西地区塔66井区油气高产与同生断层有关。In order to find out the relationship between the structural formation and the petroleum reservoir accu- mulation in Songliao Basin, with the help of the theories of the differential compaction structure and inversion tec- tonics, from the viewpoints of the three main influencing factors i. e. the basement heave, tectonic compression, and differential compaction, the influencing factors of the six tectonics and the influenced degrees of each one in the basin were analyzed, and moreover the relationships between the structures and hydrocarbon accumulation were re- searched as well. The study achievements show that the sandstones are well developed in the most of the positive structures of Songliao Basin, after the differential compaction forms in an embryonic way, the structural uplift am- plitude becomes serious and develops into a certain configurations through the tectonic inversion, the inverse struc- tures are characterized by the strong severity in the east and weakness in the west; the bigger the structural uplift amplitude is, the more favorable the petroleum accumulation will be, the slowered time of the tectonic activities is the period of the petroleum reservoir formation; the oil resource in Chaoyanggou-changchunling Anticline is fromSanzhao Sag, the high hydrocarbon productivity in Well Block Ta66 is related to the syngenetic faults.
