本文介绍了一种新的AVO方法,该方法允许解释员处理实际数据(这归因于拟3-D可视化模块),避免了单独根据地震处理技术带来的种种限制。研究区(图1)位于西班牙西南部陆上Guadalquivir盆地。该盆地是一个与Betic褶皱带和向南的逆冲断层带(活动边缘)有关的前陆盆地,它位于向北延伸的古生代稳定边缘(被动边缘)上。主要储集层是上中新统的浊积岩,砂岩平均孔隙度为20%～25%。在这一地区发现了大量的天然气。
This article describes a new AVO method that allows interpreters to manipulate real data due to the proposed 3-D visualization module, avoiding the limitations inherent in seismic technology alone. The study area (Figure 1) is located on the onshore Guadalquivir Basin in southwestern Spain. The basin is a foreland basin associated with the Betic fold belt and the southward thrust belt (active margin), which is located on a north-extended Paleozoic stable edge (passive edge). The main reservoir is the Upper Miocene turbidite, sandstone average porosity of 20% to 25%. A lot of gas was found in this area.
