摘要

运用含油气盆地沉积学的理论和方法,在大量岩心、录井、测井及地震资料分析基础上,查明了渤海莱州湾凹陷古近系东二段沉积体系的类型、特征及分布规律。莱州湾凹陷古近系东二段为东断西超的断陷湖盆,发育辫状河三角洲及湖泊沉积体系,辫状河三角洲体系在莱州湾凹陷西部、南部和东南部均有发育,具备形成优质油气储层的基础条件,是油气勘探的有利区带。
The utilization the oil and gas bearing basin sedimentology's theory and the method,based on the massive core,the logging,the well logging and the seismic data analysis,the deposition system's type,the characteristic and the distributed rule of the Dong2 Formation(Paleogene) in Laizhouwan Sag,Bohai Bay has been verified.Laizhouwan Sag is one of the typical rift lacustrine basins in the Bohai Gulf Basin,the fault boundary on the east,and onlap in the west,the braided river delta,fan delta and the lacustrine deposit system developed in the sag.The braided river delta system developed in the western,southern and southeast part.The braided river delta distribution area,developed high quality reservoir of oil gas,is the oil-gas exploration favorable area belt.
