川东北元坝地区长兴组顶部沉积体地震相研究
|
摘要
对川东北元坝地区长兴组地层开展了地震地质综合研究,根据合成地震记录,将井与地震资料紧密结合,建立高能的礁滩、低能的灰泥的地震识别标志.运用层序地层学标准化理论,在划分地震层序的基础上,结合地震反射波的振幅、频率、内部反射结构和外部几何形态等地震参数,对地震相进行划分命名,在长兴组共识别出了8种基本地震相类型,将其归类分析研究,划分为高能相带(礁、滩)和低-中能相带(礁间、盆地、斜坡、陆棚、海湾和泻湖)两大类.准确地刻画了高能礁滩相带和低能灰泥相带的分布,展示了最有利相带.
According to Synthetic seismogram,combined with well-logging data and seismic data,the present paper discusses the comprehensive research seismic and geology of Changxing Formation in Yuanba area of northeast Sichuan,form identification marks of High-energy about organic reef and bank reef,Low-energy about plaster.Applying Sequence stratigraphy theory of standardization,to divide seismic sequence,combined with the characteristics of seismic reflection such as amplitude,continuity,interior structures and exterior shapes,seven seismic facies.Study shows that the Changxing Formation can be divided into eight seismic facies,classified to Hing-energy Facies(organic reef,bank reef) and Low-energy Facies(reef between,basin,slop,shelf,bay,lagoon).
