| 摘 要： | 在地震、测井、岩心、地球化学等各种资料的基础上将松辽盆地滨北地区划分为3个一级层序,11个二级层序,16个三级层序。重点研究青山口组、姚家组以及嫩江组的层序特征,分析了滨北地区油气勘探缓慢的原因,指出下一步油气勘探的方向,确定有利隐蔽圈闭的勘探目标为青山口组中的透镜状砂体以及姚家组的河流相薄层砂体。 |
| 关 键 词： | 松辽盆地滨北地区 层序地层学 隐蔽圈闭 青山口组 姚家组 |

| Abstract: | Based on seism, well - logging, core and geochemical materials and so on, the Binbei Area of Songliao Basin can be divided into 3 first - order sequences, 11 second - order sequences and 16 third - order sequences. Studies have been focused on the sequence characters of Qingshankou Formation, Yaojia Formation and Nenjiang Formation. Analysis has been done about why the exploration of oil and gas in Binbei Area was so slow. The paper also points out the direction for the next exploration. And the favorable exploration target of subtle trap has been set. They are the sand lens in Qingshankou Formation and the thin sand bodies of fluvial facies in Yaojia Formation. |
