摘要(Abstract)：
青山口和嫩江组早期发生两次大规模湖侵,是松辽盆地地质发展演化史上的两次重要事件。应用层序地层学的基本原理对中、上部含油组合的初步分析表明,青一段和嫩一、二段分别属于两类不同沉积层序的湖侵体系域。根据湖侵体系域在层序中的位置,可初步建立中、上部含油组合的层序地层学格架。
Two large scale lake transgresions early occured in Qingshankou and Nenjiang Formations are two important events in the geological evolution, histpry of Songliao basin. Using the general principle of the sequence stratigraphy, the medium-upper oil-bearing assemblage of Songliao basin is analyzed, showing that Qing. 1 and Nen. 1 & 2 Members respetively belong to lake transgressivc systems in two types of depositional sequences. Sequence stratigraphic framwork of the assemblage may be established based on the position of the lake transgres-sive system in the sequence.
