本文通过搜集松辽盆地区域相关地质资料结合项目中的钻孔岩心和测井等资料,从区域概况、层序地层骨架和层序地层发育特征等主要三个方面对松辽盆地长岭坳陷层序地层特征进行分析研究。进而划分出构造层序等级、层序地层格架特征、层序发育以及沉积充填特征、构造地理格局和沉积类型。
Based on the data of drilling core and well logging in the related geological data in the Songliao Basin and the logging data, the paper analyzes the regional profile, sequence stratigraphy skeleton and the sequence stratigraphic development characteristics of the Songliao Basin Changling Depression Sequence stratigraphic features are analyzed and studied. Furthermore, the tectonic sequence, the sequence stratigraphic framework, the sequence development, the sedimentary filling characteristics, the tectonic geography and the sedimentary types are divided.
