摘要:: 迈陈凹陷古近系为南断北超的箕状凹陷。不同的构造带发育不同的沉积体系,迈陈凹陷东部可分为4个构造岩相带。重点区带为斜坡带、南部断裂带和东部断裂带,分别对应北斜坡河流—三角洲、南部单级或多级边界断裂陡坡扇、东部单级边界断裂陡坡扇3个构造岩相带。分析其构造特征、沉积特征及圈闭类型,指出不同构造岩相带下部勘探方向。

Abstract:: Maichen Sag in Paleogene is a half graben depression with fault in the south and override in the north.Different structural zones developed into different sedimentary systems.And the east of Maichen Sag was divided into four tectonic-lithofacies.The major structural zones are slope belt,south fault belt and east fault belt,which respectively corresponds to north slope structure fluvial-delta tectonic-lithofacies,the southern single-stage or multi-stage boundary fault steep slope fan tectonic-lithofacies,and the eastern single-stage boundary fault steep slope fan tectonic-lithofacies.The sedimentary characteristics,tectonic characteristics and trap type are analysed,and the next-step exploration direction in different tectonic-lithofacies is pointed out.
