【摘要】 通过地质、测井、地震及室内综合分析 ,总结了东营凹陷东部沙河街组三段滑塌浊积砂体的沉积特征 ,认为滑塌浊积砂体的发育与古代三角洲的进积作用密切相关 ,可进一步划分为 5种沉积微相 ;同时建立了该区滑塌浊积砂体的垂向序列和演化模式 ,分析了滑塌浊积砂体的分布规律 ,丰富和发展了陆相湖泊浊流沉积的理论和内容更多还原

【Abstract】 Sedimentary characteristics of creeping turbidite sandbodies of the Member 3 of Shahejie Formation in eastern Dongying Depression are summarized in terms of geological, well test, seismic and office analysis. This paper considered that development of creeping turbidite sandbodies are great connected with advance-action of archaic delta, which can be divided into five microfacies. Meanwhile, the vertical sequence and evolution models of creeping turbidite sandbodies in this area are established. Furthmore, the distributing regularity of them are analysed. The turbidity deposits theory and content of continental lake have been developed.更多还原
