| 摘 要： | 在对Sirius叠前深度偏移软件应用开发的基础上,分析讨论了Sirius 2D叠前深度偏移速度模型建立、层析成像及演、叠前深度偏移以及深度聚焦等技术环节的基本原理,并以莺歌海盆地某测线的处理为例,具体分析了Sirius 2D叠前深度偏移处理的流程、主要参数及时效.文中还分析讨论了莺歌海盆地中央“泥拱带”叠前深度偏移处理的地质效果.实践表明,莺歌海盆地广泛发育的与“泥拱模糊带”有关的构造各有其特殊性,只有通过3D叠前深度偏移处理才能从根本上解决“泥拱模糊带”的成像问题.

| Abstract: | Based on the application of Sirius 2D pre-stack depth migration software, the principle of depth-velocity model building, reflection tomography inversion, pre-stack depth migration methodology and depth focusing analysis of Sirius have been discussed. Taking one seismic line in Yingehai Basin as an example,the flow-chart,the main parameters and the efficiency of 2D Sirius pre-stack depth migration processing have also been analyzed and the geologic effectiveness of the application of pre-stack depth migration has been discussed. The exploration and geologic study reveals that every structure in Yingehai Basin,widely distributed and related with "mud diapir fuzzy reflection zone",has its own specialty. Only by 3D seismic survey and 3D pre-stack depth migration,can the image of "mud diapir fuzzy reflection zong"be obtained. |
