从EAGE第66届年会看多分量地震技术的新进展
|
摘要
多分量地震技术在储层描述及复杂地质条件下的构造成像方面的独特作用,吸引着地球物理学家不断地致力于此技术的发展与完善。EAGE第66届年会反映了人们对多分量地震现状的认识。会上介绍了多分量地震数据处理的新进展,包括纵波一转换波波组对比,转换波转换点坐标计算,双折射分析校正,转换波速度分析及偏移技术的新成果。
Continuous efforts have been devoted to improve multi-component seismic technology due to its unique role in reservoir characterization and structure imaging under complex geological settings. Based on information collected in EAGE 66th annual meeting, in this paper we briefly discussed the present state and coming challenge of multi-component seismic, summarized the advances in multi-component seismic data analysis which involve PP-PS event correlation, conversion point calculation, birefringence analysis and correction,C-wave velocity analysis and pre-stack time migration in VTI media.
