摘　　要：在油藏开发过程中,合理运用地震信息是当前地震技术应用发展的新领域。以下第三系戴南组岩性油藏开发研究过程为例,介绍了运用全三维解释技术、地震反演技术、属性分析技术,根据地震资料预测薄砂层。通过对第一、第二油层组储层对地震波组特征影响的分析,确定产生波峰波谷特征的主要作用因素,利用波峰和波谷的振幅信息,先后求取储层总厚度、第二储层厚度和第一储层厚度。应用此方法获得的薄层预测结果与后期实钻结果较为一致。Application of seismic information in reservoir development is the frontier of seismic technology. This paper illustrates how to predict thin sand via true 3-D interpretation, seismic inversion, and attribute analysis on seismic data from the lithologic reservoir of the Lower Tertiary Dainan Formation. For the two reservoirs in ques- tion, we firstly determine the factors controlling the characteristics of wave's peak and trough by analyzing the characteristics of seismic waves, and then predict the accumulated thickness of the reservoirs and the thickness of each reservoir using amplitude information of wave's peak and trough. The predicted results are in good agreement with drilling results.
