摘　　要：东营凹陷北部陡坡带砂砾岩体分布广泛,但成因复杂。研究发现,平面上,砂砾岩体发育明显受陈家庄凸起控制,靠近北部陈家庄凸起方向的砂砾岩体厚度大,整体呈北厚南薄,由区域轴线向东西两侧减薄;纵向上,砂砾岩体为退积过程中的沉积,剖面呈叠瓦状。进而以砂砾岩体分布规律为基础,总结了区域内的油气分布规律。Glutenite is widely distributed in the north steep slope of Dongying Depression but with complex genesis. The development of glutenite body obviously subject to Chenjiazhuang bulge. The glutenite is thick in the north close to the bulge,i.e. thick to the north and thin to the south,and thinning from regional axis to both east and west. Vertically,the glutenite body was deposited during retrogradation process,showing imbricate arrangement. Oil and gas distribution is generalized based on glutenite distribution.
