摘　　要：青东地区是胜利油田勘探程度较低的地区之一,基于该区地层发育特征认识不足以及油气分布规律不明朗等问题,首先在构造、油藏类型、测井和地质资料基础上对研究区发育形态位置进行剖析,在明确了青东地区地层发育特征的基础上,结合烃源岩热分解资料,对该区烃源岩进行了研究,通过分析已钻井热解数据找出主要油源层以及生油潜力区,从绘制的沙四上亚段暗色泥岩等厚图和沙三下亚段暗色泥岩等厚图可以得到砂体在平面的上分布规律,进而初步确定了该区烃源岩特征以及油气在横、纵向上的分布规律,研究结果有利于对青东凹陷进行深入挖潜,为后续勘探开发提供地质依据。Qing-dong sag is one of the lower exploration areas of shengli oil field, based on the formation and development characteristics and oil and gas uncertain distribution regularity, first, with the structure, reservoir types, the geological data and well logging, the position and formation development form of the research area was analyzed. On the basis of the formation and development characteristics of Qing-dong sag, combined with the hydrocarbon source rock pyrolysis data, the hydrocarbon source rocks in the area was studied. Through the analysis of drilling pyrolysis data, the main oil source layer and genetic potential area, with the dark mudstone isopach map of Es3 and E% were found out,which could get the distribution of sand body on the plane. The characteristics of the hydrocarbon source rocks and the horizontal, vertical distribution of oil and gas were determined. The result of the study is beneficial to to carry out in-depth exploration of Qing-dong sag, providing geological basis for further exploration and development.
