摘　　要：通过对下二门油田沉积岩颜色、沉积构造特征、重矿物分布特征、粒度分布特征及砂体展布形态进行研究,为该区物源和古流向分析提供有力的证据。分析认为该地区存在两个物源方向沉积,北部的侯庄辫状三角洲沉积和东部的近岸扇三角洲及重力流沉积。Through the analysis of the sedimentary rock color, sedimentary structure, distribution characteristics of heavy minerals, particle size distribution and sand body distribution, the source direction and paleo-flow direction of Xia'ermen oilfield have been made clear, which provides powerful evidence for further studies. The results show there are two source directions. One is braided delta depositional system in the north and the other is nearshore fan delta and gravity flow system.
