摘要
基于两江地区青山口组泥岩盖层的宏观、微观封闭特征以及Ｔ２断层的封闭特征，对其封盖能力进行了综合研究；该区大部分地区具有好—中等的封盖层能力，并且其封闭能力形成时期早于其自身的排油期。封闭扶杨油层油的有效性好，有利于扶杨油层油的大规模聚集与保存，是该区扶杨油层至今能找到一大批油田的重要原因之一。
The sealing ability of mudstone caprock of Qingshankou formation in the area between Nenjiang River and Songhuajiang Rivers is comprehensively studied based on the macroscopic and microscopic sealing ability,and so is the T2 fault.It is considered that its sealing ability is good to better in the area ,and the period of forming the ability is earlier than that of the oil expulsion by itself.Its sealing ability for the FuYang oil reservoirs is effective.It is favorable for the accumulation and preservation of oil in the FuYang reservoir is large scale,and is one of the important factor,which made many oil fields still could be found in the FuYang reservoir in the area.
