摘要
东营凹陷下第三系沙三下亚段孔店组具有陡坡 (断阶 )带—扇三角洲构造岩相带、缓坡带—三角洲及滩坝 -湖底扇构造岩相带、深陷带 -远岸及滑塌成因湖底扇构造岩相带和凹中隆起 (中央隆起 )带 -滩坝及滑塌成因湖底扇构造岩相带等四个构造岩相带。油气成藏受到沉积相带、成岩相带和构造位置的共同影响 ,因而在东营凹陷不同的构造岩相带具有各具特色的沉积、成岩和油气成藏模式。
The Paleogene in Dongying Sag is composed of four zones of tectonic lithofacies, including zone of steep slope fan delta tectonic lithofacies, zone of gentle slope delta and beach bar sublacustrine fan tectonic lithofacies, zone of deep sag distal bank and slumped sublacustrine fan tectonic lithofacies and zone of central uplift beach bar slumped sublacustrine fan tectonic lithofacies. Since the for mation of pools is inflenced by sedimentary facies and tectonic location, the models of sedimentology, diagenesis and pool are of different characteristics in the 4 different tectonic lithofacies zone in the Dongying Sag.
