| 摘 要： | 关于层序地层学在陆相湖控条件下的适用性探讨一直在不断地进行着，尤其是陆相油气盆地占优势的中国，陆相层序地层学的研究已处于世界先进的行列。其中对松辽盆地层序地层的研究引人注目。层序地层学理论对于陆相盆地适用性问题的探讨，产生了众多层序地层学学派。笔者总结探讨了层序控制的基本因素与盆地类型的关系，在此基础上研究了断陷期层序地层发育特点。首次对晚侏罗世—早白垩世的松辽盆地徐家围子裂陷盆地阶段的地层——火石岭组、沙河子组与营城组，进行了层序地层分析，对可容空间变化与充填情况进行了研究，划分了超层序，对其中的火山岩地层、沉积岩地层分别进行了研究，并总结了火山作用与沉积作用的相互关系。从可容空问概念出发，把火山岩地层纳入层序框架．并对层序控制下的生储盖组合及油气勘探远景进行了评估。

| Abstract: | The applications of the principle and method of sequence of rifting basin is being researched by many workers. Especially the research of sequence of Songliao Basin in China where the continental oil and gas dominate in energy resources draws more and more attention from geologists. Some schools are formed for theory of sequence,such as tectonic theory, climate theory and comprehensive theory. This paper discusses relationship between sequence types and basin types, and then the oil and gas promising and sequence of rifting basin,and analyzes strata of Late Jurasic and Early Cretaceous period of rifting basin, i.e.Huoshiling Formation, Shahezi Formation and Yingcheng Formation.According to analysis of sequence of these strata,the changes of accommodation space and its filing process were investigated,and then divided the ultra sequence.The relationship between sedimentation and volcanism was investigated.From the concept of accommodation space,volcanic rocks were put into the frame of sequence,and the system of hydrocarbon-reservoir-cover controlled by sequence and the oil and gas exploration potential were evaluted. |

| Keywords: | rifting basin control factors of sequence sequence frame source-reservoir-cover complex |
