Be in from 1912 in relics of culture of the neo - lithic age of village of yang shao of county of henan mian pool after discovery , the province area such as gansu province , qinghai , shaanxi , ningxia , henan , heibei , shanxi , shandong , jiangsu , sichuan , hubei all comes up out of land in succession , they belong to different culture type respectively 自1912年在河南渑池县仰韶村新石器时代文化遗址中发现后，甘肃、青海、陕西、宁夏、河南、河北、山西、山东、江苏、四川、湖北等省区均陆续出土，它们分别属于不同的文化类型。

The mathematical statistics method and extrema variance clustering method can be used to visible automatic classifying and reading of logging curves . the lithofacies classifying program basing on multi - mineral model analysis presents a new method to analyze logging - facies and more accuracy and visualized logging facies section can be reached by using this method . in addition , it supplies reliable lithologic layering reference for search and evaluation of oil / gas caprock and it also made up for the high cost of core - drilling and the inaccuration between lithic fragment description and depth 采用基于“数理统计-极值方差聚类法”的面向对象可视化操作方法可有效地解决测井曲线的可视化自动分层取值问题；而基于多矿物模型分析的岩相划分程序又提供了一种新的测井相分析方法，能得到更为准确直观的测井相剖面，为寻找和评价油气盖层提供了可靠的岩性分层依据，同时弥补了钻井取心费用高和录井岩屑描述与深度有误差的缺陷。

According to the regional geology and the character of the lithofacies and well - logging facies , 4 kinds of sedimentary facies and 3 kinds of depositional system : marine system , delta system and fluvial system have been identified . the sedimentary facies of taiyuan formation is marine faceis , up to sanxi formation , the sedimentary facies is delta facies , the xiashihezi formation hel and he2 member are braided river facies , he3 member is meandering river facies . the mains types of sandstone of taiyuan formation are lithic quartzarenite and quartzarenite ; the mainly types of sandstone of sanxi formation and xiashihezi formation is litharenite 通过对20余口井2000多米岩心的观察和对40几口井的测井数据解释、对比，在研究区目的层段识别出了12种基本岩相和9种测井相类型，在区域沉积背景和单井相划分的基础上，根据岩相和测井相组合特征，在太原组?下石盒子组划分出4种沉积相和若干沉积微相，并进一步划分为3类沉积体系：滨浅海沉积体系、三角洲沉积体系和河流沉积体系。
