摘要
在详细研究岩心、测井等资料的基础上,结合区域构造背景,运用现代沉积学理论和方法,对长春岭地区登娄库组地层进行沉积体系类型、特征进行分析。将长春岭地区登娄库组划分为4个三级层序(SQ1—SQ4),共识别出扇三角洲、辫状河三角洲、湖泊、辫状河和曲流河沉积体系,最后应用层序地层学的观点对本区沉积相带的时空演化规律进行分析。
On the basis of studying the materials of the drilling core,the logging and the indoor analysis combining the tectonic background,using of the theory and method of the modern sediment logy,the type and character of denglouku formation is analysed.The Denglouku formation in Changchunling area is divided into four three-order sequences（SQ1—SQ4）,among which sedimentary facies are identified,fan delta、braided channel delta、lake、braided river and meandering river.At last with the opinion of sequence stratigraphy,development history of depositional system is analyzed.
