摘要
介绍了SIRIUS3D叠前深度偏移软件的技术特点及工作流程,分析了该软件的优点和不足.将该软件首次应用于BZ25-1构造,通过精细的速度反演,建立了较为准确的三维速度模型,最终叠前深度偏移结果较为理想,尤其是中浅层复杂断层的成像质量得到明显提高,为BZ25-1构造评价提供了重要依据.
This paper first describes technical features and flow diagrams of SIRIUS3D software for pre_stack depth migration, and analyzes its advantages and shortcomings. As a first application in BZ251 structure, SIRIUS3D has built a more exact 3D velocity model by refined velocity inversion, obtaining more perfect pre_stack depth migration. Most importantly, imaging of complex faults in shallow_middle depth is greatly improved, providing a significant basis for evaluation of BZ251 structure.
