摘要
地震属性不仅能用于构造解释、储层解释 ,还能用于沉积环境解释。本文利用层拉平振幅切片进行储层和沉积环境解释。泉四段地层在地震反射剖面上呈现 4个相位组成的波组 ,从与钻井和测井资料的对比中发现 ,其中每个相位均有确定的地质意义。经层拉平处理后 ,一些地质现象明显呈现出来 ,例如河道展布、多期叠置扇形沉积体、顶超、下超等 ,为储层和沉积环境解释提供了可靠依据。
Seismic attributes are not only used for structure interpretation and reservoir interpretation,but also used for interpretation of sedimentary environment.The paper used the layer-flattened amplitude slices to interpret the reservoir and sedimentary environment.The Quan Formation forth segment showed the wave group consisted from 4 phases on seismic reflected sections.It is discovered from correlation with drilling and logging data that each phase has definite geologic significance.Some geologic scenarios are clearly showed after layer-flattened processing such as channel distribution,multi-period stack fan sedimentary body,overlap of upper layer and lower layer that provided a reliable basis for interpretation of reservoir and sedimentary environment.
