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。
The glutenite bodies in the steep slope belt in the northern part of Dongying Sag are widely distributed, but the causes are complex. The study shows that in the plane, the glutenite body is obviously controlled by the Chenjiazhuang bulge, and the glutenite body near the north of the Chenjiazhuang bulge has a large thickness with a north-south-south-thinning thinning from the regional axis to the east and west sides. In the longitudinal direction, The glutenite body is sedimentary during the de-deposition process and the section is shingled. Then based on the distribution of glutenite body, the law of oil and gas distribution in the area is summarized.
