| 摘 要： | 根据工区内现有的钻井、测井和地震资料，应用以多级次基准面旋回为参照面的高分辨层序地层学理论与研究方法,对松辽盆地南部海坨子—大布苏地区的泉四段—姚家组地层进行了详细的层序地层研究，共识别出5个长期基准面旋回（相当于三级层序），9个中期基准面旋回（相当于四级层序），建立了研究区的层序划分方案，在连井剖面的层序地层对比基础上，建立了该区的地层格架，并对层序构成特征进行了分析，研究了储集层在层序格架内的分布规律，揭示出浊积砂体和三角洲前缘相的分流河道形成于基准面上升期，三角洲前缘相的河口坝、远砂坝和席状砂沉积形成于基准面下降期，指出浊积砂体和三角洲前缘相的远砂坝、席状砂沉积是研究区形成岩性油气藏的有利储集体。

| Abstract: | Guided with the theory of high resolution sequence stratigraphy and based on cores,well logs and seismic materials,the sequence stratigraphic scheme of the Member 4 Quantou Formation to Yaojia Formation in Haituozi-Dabusu area has been constructed,which is composed of 5 long term base level cycles(third order sequence)and 9 middle term base level cycles(fourth order sequence),and the sequence stratigraphic framework has been discussed.The result shows that turbidite sand body and distributary channels of delta front mainly develop at the half cycle increasing period and mouth bar,distal bar and sheet sand of delta front mainly develop at the half cycle decreasing period.The turbidite sand body and distal bar,sheet sand of delta front are favorable reservoirs in the study area. |
