【摘要】 针对传统计算面元尺寸和覆盖次数公式存在的问题,本文重新界定了"面元"和"面元覆盖次数"的概念,提出新的计算公式,使得计算公式更加客观地反映三维面元和覆盖次数的关系,具有更广的使用范围。根据新的计算公式,结合横向观测系统分析,更好地分析观测系统特征,一方面通过细化面元大小,提高地震分辨率;另一方面,可以根据处理要求,进行超级面元组合处理,结合组合前的去噪和静校正处理,提高地震资料的信噪比。这样既可以给地震勘探观测系统设计提供新的思路,又可以在地震勘探野外采集设计中,发挥灵活设计面元的优势。更多还原

【Abstract】 In view of the problems existed in traditional formula computing bin size and folds, the paper redefined the conception of bin and presented new computation formula, making the computation formula have wider usage scope. According to new computation formula, the feature of geometry can be better analyzed in combination with the analysis of crossline geometry: on the one hand, the seismic resolution can be improved by fine-sorted bin size, and on the other hand, the super-bin array processing can be carried out based on processing, which can improve S/N ratio of seismic data in combination with pre-array processing of denoise and static corrections. Doing so can both present new idea of design of seismic geometry and play the superiority of flexibly designing bins in the design of seismic field acquisition.更多还原
