| 摘 要： | 基于观测系统设计在勘探中的重要性,本文通过探讨三维设计过程中,选择不同的道间距和炮线距进行不同CMP面元、不同覆盖次数、炮检距、方位角的对比分析,进行观测系统的优化设计,结果表明宽方位角的10线8炮观测系统较其它常规的观测系统在保证覆盖次数的前提下,炮检距和方位角的分布上更加均匀,更加有利于压制采集过程中的采集脚印。

| Abstract: | Observation system design is critical in detection.The paper discusses comparison analysis of different CMP surfaces,fold numbers,offsets and azimuths with different group intervals and offsets in the 3D design and the optimal design.The result shows that observation system of broad azimuth is better compared with other conventional systems in more equal distribution of offset and azimuth,which is beneficial for suppressing acquisition footprint during the sampling process. |

| Keywords: | 3D observation system surface attribute offset fold number azimuth |
