【摘要】 减小面元尺度,增加空间采样率,是提高分辨率的重要手段之一。本文以永新地区高精度地震采集为例,分析了当前地震采集密度指数的计算方式,在介绍该区采集资料品质的基础上,通过理论分析结合实际资料,分析面元大小、覆盖次数与资料品质之间的关系,对各种面元组合方式所得资料品质进行对比,认为该区高精度采集以10m×10m面元为宜,室内处理时浅、中、深层分别宜选用10m×10m、15m×15m及25m×25m面元。更多还原

【Abstract】 Reducing bin size and increasing spatial sampling rate are one of important means for improving resolution. Taking high-resolution acquisition in Yongxin area as an example, the paper analyzed the computational way of current seismic acquisition density index; on the basis of introducing the data quality acquired in the area, analyzed the relationship among bin size, folds and data quality in combination of theoretical analysis with practical data. It is considered by correlation of data quality acquired by different bin array pattern that it is appropriate to use 10m×10m bin size in an area of high-resolution acquisition and to select10m×10m, 15m×15m and 25m×25m bin size for indoor processing of shallow, mid and deep layer respectively.更多还原
