地震反射及属性对沉积相反映程度分析
|
摘要
结合陆相环境下不同沉积体的特征及其地震响应,将陆相典型沉积体划分为4种类型:浊积前积及河道切割平原沉积、垂向渐变平面稳定湖泊沉积、洪积近岸水下扇体沉积和湖泊边缘湖水动力沉积,并分别总结了其沉积特征、宏观地震反射规律。结合不同沉积体纵向岩性组合规律、平面分布特征以及与地震反射的对应规律,分析了地震反射对沉积相(或储集体)的反映程度。在此基础上,结合地震属性的本身不可靠性分析,对地震属性对于沉积相(或储集体)描述的可靠程度进行了评价。
According to the different sedimentary features and seismic response for the continental facies,the typicallithotomic body is divided into four types:turbidite and river cut-off plane deposit,vertical gradual change lacustrinedeposit,diluvia coastal fun-shaded deposit and lacustrine margin hydrodynamic deposit.The paper summarizes thedeposit feature and the reflecting law of macroscopic seismos.Meanwhile,the seismic data have different reactionsto different continental sedimentary types,but there is not a one-by-one correspondence relationship between them.With the summary on the basic reflection feature for continental sedimentary types,the paper presents the researchin the seismic reflection degree for sedimentary facies and the reliability of impact of the seismic for the descriptionof sedimentary body.
