摘要
传统的沉积相研究中,地震相根据地震反射结构特征来识别,该方法具有一定的不确定性,其精度难以满足岩性地层油气藏勘探开发对沉积(微)相研究的需要。地震储层预测技术更充分地利用了地震资料中的信息,为地震相定量化研究提供了技术手段,为最终实现井间及无井区沉积相的定量研究提供了保障。以歧北斜坡为研究区,综合运用基于波形分类的地震相分析技术、地震反演技术对井间和无井区砂岩进行定量预测,最终实现沉积相的定量分析。
The seismic facies was identified by seismic reflection configuration in traditional sedimentary facies research.This method had uncertainty and could not satisfy the needs of accuracy in stratigraphic/lithologic trap exploration.Seismic reservoir prediction technologies utilize the seismic data more sufficiently and can analyze quantitatively the seismic facies and then can make the sedimentary facies research more accurately in the area.
