摘要
二连盆地位于内蒙中部,是中国陆地上11个大型沉积盆地之一。43个凹陷和21个凸起形成凹凸相间的构造格局,4个高产油田位于阿南凹陷中。有正常湖泊、冲积扇(锥)-沿岸水下扇、冲积扇-辫状河-扇三角洲、扇三角洲(沿岸水下扇)-湖底扇、风暴流-重力流、湖坪-砾屑浅滩、滨浅湖滩、沼泽化冲积平原-小型湖泊、火山喷发等9种沉积体系。其中沿岸滩坝、扇三角洲前缘和沟道浊积岩是主要含油气岩系。
Erlian basin located in central Inter Mongolia is one of thelarge sedimentary busins in China.The basin's structural framework consists of 43 depressions and 21 uplift s.There are four highly productive oil-fields in the basin..Nine sedimentary systems have been recognized,including normal lan-eust rine,alluvial fan-longshore subaqueous fan,alluvial fan-braided channel-fan delta,fan delta-sublacus t rine fan,s torm flow-gravity flow,lake flat-rudaceous shoal,longshore beach,marshy alluvial plain-small lake and volcanic extrusion.The major hydrocarbon-bearing formations arc deposits of longshore shoal,fan delta front and channelized turbidite.
