| 摘 要： | 东濮凹陷濮城油田沙四下是一套紫红色砂泥岩,其沉积特征反映一种比较特殊的滨湖亚相环境,可分为砂坪微相、砂泥混合坪微相和泥坪微相。沙四上—沙三~3有四种岩相:暗色泥岩及页岩相浊积岩相,石膏及盐岩相,黑色硅质岩相。四种岩相的组合反映深湖-半深湖环境。本文着重进行浊积岩相分析,初步探讨了四种岩相组合的形成机制,指出了断裂-岩相-形成油气藏的相互关系。

| Abstract: | A set of purplish red sand-muds tone was deposited below S4 of Pucheng oilfield. The sedimentary characteristics show a fairly special shore-lake suhfacies environment which can be divided into three microfacies. sand-flat, sand-mud mixed flat and mud-flat. There are four types of Lithofacies above S4 and S33 formations. They are dark-coloured mudstone-shale lithofacies, turbidite lithofacies, gypsum-salt lithofacies, black chert lithofacies.The combination of four types of lithofacies shows deep or semi-deep lacustrine environment. Turbidite lithofacies has been mainly analyzed, in this paper. The mechanism of four types of lithofacies combination has been investigated. The relationship among fault, lithofacies and accumulation of oil and gas has been presented. |
