摘要
本文运用层序地层学、高分辨层序地层学、储层地质学的理论与分析技术,查明了渤海莱州湾凹陷古近系东三段沉积体系的类型、特征及分布规律。莱州湾凹陷古近东三段发育辫状河三角洲、扇三角洲及湖泊沉积体系,辫状河三角洲体系发育于莱州湾凹陷西部、南部和东北部,扇三角洲发育于莱州湾凹陷西南侧,辫状河三角洲和扇三角洲分布区优质油气储层发育,是油气勘探的重点区带。
The utilization Sequence Stratigraphy,the High Resolution Sequence Stratigraphy,the reservoir geology's theory and the parsing technique and the method,the deposition system's type,the characteristic and the distributed rule of the Dong3Formation(Paleogene) in Laizhouwan Sag,Bohai Bay has been verified.Laizhouwan Sag developed 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 northeast,fan delta developed in the southwest part.The braided river delta and the fan delta distribution area,developed high quality reservoir of oil gas,is the oil-gas exploration key area belt.
