摘　　要：在河流－三角洲沉积体系中采用泥砂比定量描述了决定地层沉积模式的可容纳空间与沉积物供给速率比这一抽象而又重要的变量，使用的关键技术包括：测井岩相自动划分、泥砂比曲线定量计算以及测井曲线滤波等。并综合利用测井岩相、泥砂比曲线以及自然伽马趋势分析曲线自动划分高分辨率层序。利用这一技术可极大提高高分辨率层序地层划分的效率和精度。The formating sedimentation model is controlled by the accommodating space to sediment sapply ratio. Forriver-delta sedimentary system, shale to sand ratio can be used to describe quantitatively the ratio of accommodationspace to sediment supply rate. The key techniques used include: automatic recognizing log-facies, quantitative calculation of shale/sand ratio curves and log curve filtering. The techniques could considerably improve the efficiency and accuracy of the recognition of high-resolution Sequence stratigraphy.
