摘　　要：沉积相的划分，实质上就是对古沉积环境的划分。所谓沉积环境就是地球的一块相对“独立”的表面，即一个发生沉积作用的地貌单元，如河流环境、三角洲环境等，它具有独立的生物、物理和化学特征。这些特征亦即是古环境的物质表现，包括沉积岩石学的各种特征，如成分、结构、构造、生物、层序、砂体形态、剖面构造、横向变化等等，它们都是判别古环境的标志。在一系列连续或离散的测井资料中，包含了丰富的各种地下地质特征和沉积环境信息，从中提取出表征沉积环境的各种特征参数，建立起某地区的沉积相测井相模型，应用模式识别的各种处理方法。The division of sedimentary facies is actually that of paleosedimentary environment.The socalled sedimentary environment is exactly a piece of relatively independent surface of the earth,namely,a morphologic unit,in which the sedimentation occurrs,such as fluvial environment and delta environment,etc.,being of independent biological,physical and chemical characteristics.These characteristics are namely those the palaeoenvironmental matters have,including the various characteristics of sedimentary petrology,such as component,structure,organism,sequence,sandbody geometry,profile structure and lateral change,etc.,which are entirely the marks for recognizing palaeoenvironment.The various abundant informations about subsurface geologic characteristics and sedimentary environment are contained in a series of continuous or scattered logging data.Through drawing various characteristics parameters showing sedimentary environment from the informations to set up the log facies model of the sedimentary facies of some areas and applying various processing methods to pattern recognition,the various sedimentary facies and microfacies of some areas can be divided.
