地震解释技术新进展

Advances in seismic interpretation

介绍第 6 5届EAGE论文中以地震解释技术为主的文献内容 ,如三维可视化、振幅属性分析、地震反演、构造成图等。这些技术可用于解决复杂的地质、油气问题。例如 ,将三维可视化技术与AVO技术联合应用 ,能快速识别具有不同AVO特征的地质异常体和含气储集体 ;在振幅属性时间切片上可精确地鉴别在地震剖面上很难识别的火山体 ;用地震反演技术解决岩性复杂、横向多变的薄砂岩储层的预测问题等。

This paper introduced the advances in seismic interpretation reflected from the 65 th EAGE annual meeting. Topics included 3-D visualization, seismic attribute extraction, seismic inversion, and structure mapping. These techniques are used to resolve the complicated geology and hydrocarbon problems. The combination of 3-D visualization and AVO techniques was used as a quick way to detect the geologic anomalies of various AVO characteristics and hydrocarbon reservoirs. Volcanic bodies that are difficult to identify at seismic sections can be discriminated undoubtedly at seismic time slices. Seismic inversion facilitates the prediction of thin sand reservoirs of variable lithology and lateral facies.
