南黄海盆地两条地震剖面的重磁数据联合反演效果
|
摘要
南黄海盆地奠基于前南华纪变质基底之上,盆地演化历经南华纪—早、中三叠世海相地层发育期、晚白垩世—古近纪箕状断陷发育期和新近纪—第四纪拗陷发育期,为一典型地台—断陷—拗陷多层结构的复合盆地。本文以南黄海盆地新近采集的两条重力、磁力、地震综合剖面为例,用2.5维重磁震联合反演技术,获得了以地震资料为约束的重、磁异常反演剖面。反演结果表明联合反演技术可用来研究盆山接触关系、断层分布、深部目的层分布和有利构造圈闭特征,为地球物理数据综合解释及油气勘探部署提供科学依据。
The south Yellow Sea Basin,based on the pre-Nanhua metamorphic basement of the Lower Yangtze Platform,is a polycycle basin with a sandwich-type construction.The geologic evolution of the basin can be divided into three stages:the Nanhua-early and middle Triassic marine basin stage,the late Cretaceous-Paleogene graben fault basin stage and the Neogene-Quaternary depression basin stage.Gravity and magnetic anomalies restrained by seismic data are inverted by 2.5D gravity-magnetic-seismic inversion from newly acquired seismic,gravity,and magnetic data.The inversion results indicate that the joint inversion method is helpful to research the contact relation between the basin and mountains,and to identify fault distribution,deep targets and favorable structural traps in future oil and gas exploration.
