摘　　要：胜利海域埕岛油田是胜利油田重要的油气聚集带。埕岛油田东斜坡地区东营组发育一套浊积岩,是重要的油气储层类型。明确浊积砂体成因类型及沉积特征对于推动浊积岩油藏的勘探开发具有重要理论意义和实际价值。本文在前人研究成果的基础上,以沉积学原理为指导,选取东斜坡东营组浊积砂体为研究对像,综合粒度分析、地质录井、钻井岩心等资料,明确了洪水湖底扇和滑塌湖底扇两种成因的浊积砂体,分析了研究区沉积相展布,建立了沉积模式。结合相邻凹陷浊积岩油藏勘探开发情况进行了讨论。Chengdao Oilfield in Shengli sea area is one of the important oil and gas accumulation zones in Shengli Oilfield. A set of turbidites is developed in Dongying Formation in the east slope area of Chengdao Oilfield, which is one of the important oil and gas reservoir types. Clarifying the genetic types and sedimentary characteristics of turbidite sand body has important theoretical significance and practical value for promoting the exploration of turbidite reservoir. On the basis of previous research results, guided by the principle of sedimentology, this paper selects the turbidite sand body of Dongying Formation on the east slope as the research object, integrates the data of particle size analysis, geological logging and drilling core, defines the turbidite sand bodies of flood lake bottom fan and collapse lake bottom fan, analyzes the distribution of sedimentary facies in the study area, and establishes the sedimentary model. The exploration of turbidite reservoir in adjacent sag is discussed.
