摘　　要：陈家洼陷沙三段砂泥比值低,冲积扇、浊积扇及滑塌砂体等较发育,暗色泥岩成熟度较高,具有发育地层-岩性油气藏的潜力。但前人没有对沙三下亚段进行过精细层序划分,砂体成因类型分析更是少见,不能满足寻找隐蔽油气圈闭的需要。因此,在地震、钻测井及岩心资料分析研究的基础上,应用地质地球物理综合预测了沙三下亚段主要的砂体分布特征及发育模式,并探讨砂体与油气的关系,对陈家洼陷下一步的勘探提供了依据。In Sha No. 3 Member of Chenjia Sag, the sand-and-mud ratio is low, alluvial fan, turbidite fan, slump sand body and so on are well developed, the maturity of dark mudstone is pretty high, so the potential of developing stratigraphic-lithological petroleum reservoir is favorite. But the fine stratigraphic division for the lower submember of Sha No. 3 Member has not been done by our predecessors and moreover the analysis of the genesis type of sand body is rare to see, so the conditions stated above cannot meet the requirements of seeking lithological petroleum traps. Therefore on the basis of analysis and study of seismic, drilling, testing and core data, by integrating geology and geophysics, the distribution characteristics and development mode of main sand bodies in this submember can be comprehensively predicted. In addition, the relation between sand body and petroleum has been discussed. All the studied results possess a certain guiding significance for the further exploration of Chenjia Sag.
