摘　　要：浊积岩分序级描述技术是在前人研究与勘探实践基础上,以层序地层学理论为指导,结合较为前沿的地震沉积学理论,分析层序内部结构,明确了浊积岩发育序级的划分原则、对比和划分方法;以地震资料为基础,充分发挥了井震结合的优势,形成了浊积岩的地震识别模式的建立方法.本次研究建立了东营凹陷沙三段和沙四上不同类型浊积岩的地震响应模式,形成了浊积岩分序级描述技术;该技术可以用来预测新的浊积岩发育区.东营凹陷油气勘探实践证明,在浊积岩分序级描述的基础上进行勘探优化部署,可以有效的提高浊积岩油藏的勘探成功率.Based on the previous research and exploration practice, the technology of turbidite different-level sequence description is established under the guide of sequence stratigraphy and newer seismic sedimentology, which analyzes the internal sequence texture, defines the division principle and the contrast method of turhidite development levels according to the seismic data. This technology absorbs the advantages of both the seismic and well data. The method seismic identification of turbidite is proposed. This study advanees the different types of turbidite seismic response patterns in the third member and upper forth member of Shahejie Formation, Dongying Sag. This technology can be used to prospect the potential development zone of the turbidite. The exploration practice in the Dongying Sag proves that the exploration deployment based on the turbidite different-level sequence description technology can effectively improve the success rate of turbidites oil reservoir exploration.
