| 摘 要： | 运用层序地层学相关的理论、方法,通过钻井、测井以及地震反射等标志,将呼和湖凹陷南屯组二段划分为一个三级层序.依据地层叠置样式、区域分布的等时性煤层以及地形坡折带在沉积层序中的位置,进一步细分出低位、水进及高位体系域,在剖面层序对比的基础上建立了研究区南屯组二段层序地层格架.以体系域为单位分析了此层序格架内沉积体系的配置...

| Abstract: | Huhehu Depression is a key exploration area in the east grabens which is located in the southeast of Hailar Basin.The depression is a half-graben rift subsidence structure,characterized by it being faulted in the east and overlapped in the west,and its area is 2 500 km2.The 2nd member of the Nantun Formation in Huhehu Depression has developed the coal measures buried deeply whose strata formed by a set of gray siltstone and dark thick mudstone which mixed with black coal,gray fine sandstone and grey conglom... |
