摘　　要：松辽盆地发育2套主力生油岩,即青山口组一、二段和嫩江组一、二段泥岩.在2套生油岩之上、之间和之下均发育含油层,由于烃源岩与储层的空间配置关系不同,造成了油气运移方式和成藏模式的差异.通过对见油气显示井及已经发现的油气藏进行油源对比和成藏控制因素分析,把黑帝庙油层的油藏归纳为叠瓦状原生油气藏和串珠状次生油气藏2种成藏模式.叠瓦状原生油气藏受生油凹陷控制,主要分布在古龙凹陷和长岭凹陷及周边地区,油源主要来自凹陷内嫩江组生油岩;串珠状次生油气藏油源来自萨尔图、葡萄花、高台子油藏,主要分布在大庆长垣,油源主要来自青山口组生油岩.Two main sets of the hydrocarbon source rocks are developed in Songliao Basin： Member 1 and 2 mud- stones in Qingshankou Formation and Nenjiang Formation. All the oil-bearing layers are developed above, between and under these two sets of the oil-generating rocks, while the different space associations between the source rocks and reservoirs result in the differential of the hydrocarbon migrating and accumulating models. With the help of the oil source correlation between the shown petroleum occurrences and discovered hydrocarbon reservoirs and further- more the analyses of the controlling factors of the accumulations, the oil reservoirs in Heidimiao Oil Layer are gen- eralized and induced into imbracated primary and moniliform secondary hydrocarbon accumulating models. The for- mer is controlled by the oil generating sags, which is mainly distributed in Gulong and Changling Sags and the sur- rounding areas, the oil is principally from the oil-generating rocks in Nenjiang Formation of the sags; the oil sources of the latter are from Saertu, Putaohua and Gaotaizi oil reservoirs, which are mainly distributed in Daqing Placanti- cline, the oil is generally from the oil source rocks in Qingshankou Formation.
