摘要
FG地区富含钙质成分的砂岩是该区广泛分布的非均质性较强的特殊岩性体储层。本次研究根据模型正演和地震响应特征,优选了叠后地震资料特殊处理方法,利用叠后保幅偏移数据体和特殊处理数据体进行三维可视化分析和研究,刻画了钙屑砂岩这类特殊岩性体的空间展布规律,总结了该类储层的预测方法,对井位部署具有重要作用。
The sandstone that contains rich calcium component widely distributed in FG area is taken as a little strong and special lithologic reservoir heterogeneity.According to the forward modeling and seismic response characteristics,this research optimizes post-stack seismic data processing method,using post-stack migration data volume and special processing data volume.Through 3-d visualized analysis and research,we depict the spatial distribution of the calcium-rich sandstone,and summarize the predicating method of this kind of reservoir.This research plays an important role in well placement.
