摘要
国外石油公司在安哥拉深水区寻找古近系和新近系浊积砂岩油藏的勘探实践过程中,使用AVO属性分析进行烃类检测取得了很高的成功率,但也有一些区块遇到了与传统的AVO解释模板不一致的例子.通过对研究工区地震数据的分析,利用精细的地震AVO正演模拟,认识了含油砂岩的AVO响应特征,并提出了相应的AVO交汇解释思路,辅助含油气信息的检测.
AVO analysis has been successful with many cases in hydrocarbon detection in Tertiary turbidite reservoir in Angola deep water region. But there were some failed drilling cases relying on prospects from AVO study. Therefore, data oriented approach is proposed based on intensive analysis of seismic data, subtle rock physics study and forward modeling in order to improve hydrocarbon detection.
