| 摘 要： | 根据对山东东营博兴洼陷沙四段砂岩粒度特征统计，对沙四段砂岩的分选性、偏度、峰度等进行了分析，并利用萨胡粒度判别函数和C—M图解识别出浊流和三角洲（河流）沉积环境。归纳出了6种粒度概率累积曲线形态样式，最后别出湖底扇、三角洲前缘水下分流河道、河口坝和远砂坝等沉积环境。

| Abstract: | Based on the grain-size statistical analysis of Boxing Depression Es4 's sandstones,Dongying,Shandong Province,this paper acquires their grain-size parameters of sorting degree,standard deviation and peakedness etc.,and identifies turbidity current and delta(river) depositional environment by using Sahu grain-size decision function and C-M pattern.The 6 kinds of grain-size probability cumulative frequency curves indicate that depositional environment includes sublacustrine fan,delta front distributary chann... |
