地震属性分析在薄储层预测和描述中取得了广泛应用,但当多套砂泥岩薄互层由于子波的干涉在地震上表现为一个复合波时,如何确定地震属性与沉积微相之间的关系缺少系统的模型实验,为验证地震属性分析预测沉积微相的能力,建立三维地质模型,得到了振幅切片与砂体之间关系的基本认识,并利用大港油田的实际地震数据进行了分析和验证。
Seismic attribute analysis has been widely used in the prediction and description of thin reservoirs. However, how to determine the relationship between seismic attributes and sedimentary microfacies when multiple interbedded sand and shale thin interbeds appear as a complex wave due to wavelet interference? In order to verify the ability of seismic attribute analysis and prediction of sedimentary microfacies, a three-dimensional geological model was established and the basic understanding of the relationship between amplitude slices and sand bodies was obtained. The actual seismic data of Dagang Oilfield were analyzed And verification.
