摘要
针对浅地层剖面仪在东沙海区采集的浅层剖面资料中出现的随机干扰、大值干扰等问题,通过去噪处理手段进行了有效的压制,消除了干扰波对原始资料的污染;针对由于间隔性采集和处理对原始资料造成的时间延迟现象,通过时移校正方法进行了处理;针对剖面中炮号与相应导航文件中的FIX号不存在对应关系的情况,通过提取道头时间、导航时间并在FOCUS模块中编写相应程序,将剖面中炮号与FIX号的关系建立起来。改进处理后的浅层剖面资料为地质分析与解释提供了较好的基础资料。
In this paper, shallow section data in Dongsha area have been processed and studied. Random and big interferences were effectively suppressed through processing. The contamination of interference wave to original data was eliminated. The main problems solved in processing were delay correction, the correlation of anchor point and each trace, profile connection etc., providing basis for subsequent geological analysis and interpretation of shallow stratigraphic profile data.
