| 摘 要： | 在前人工作的基础上,对北黄海海区采集的浅地层剖面资料中出现的多次波、鸣震等干扰因素进行了系统的分析,并对剖面的反射品质进行了评估,将全区分为北黄海中部较轻干扰区,北黄海南部较弱干扰区,北黄海北部较重干扰区及渤海海峡周边较重干扰区。通过滤波处理,对剖面中出现的多次波、鸣震等干扰因素进行了有效的压制,消除了干扰波对原始资料的污染,为后续地质分析与解释工作提供了理想的基础资料。

| Abstract: | We systematically studied in this paper the reflection features of various disturbing-waves, such as multiple reflections, water-layer multiples and so on, and the methods to evaluate the quality of the reflection profile on the basis of previous works. The case of the North Yellow Sea was selected for examples. There are four disturbing areas in the North Yellow Sea in accordance with the intensity of the interference. After filter processing, the disturbing waves were effectively attenuated, and better data was gained for geological interpretation. |

| Keywords: | the North Yellow Sea shallow profile interference analysis |
