海上时移地震中潮汐校正应用研究
发布时间：2018-08-07 18:12
【摘要】：时移地震中两次地震资料采集时间不同,记录的潮汐量不同,导致两次资料中出现一定时差,并且采集资料时基准面不统一,所以时移地震资料处理中潮汐校正成为必要环节。本文介绍一种时移地震中基于潮位值预测的潮汐校正方法,并采用水深数据快速检验该方法计算潮汐量的合理性,也引入非一致性值作为质控两次资料潮汐校正效果的定量化参数。此外,也通过对比校正前后地震剖面,验证了该潮汐校正方法的可靠性,说明该方法实用价值高。
[Abstract]:The data acquisition time of the two earthquakes in the time shift is different and the recorded tides are different, which leads to a certain time difference in the two data, and the datum is not unified when the data is collected. Therefore, the tide correction in the time shift seismic data processing is a necessary link. The water depth data is used to quickly test the rationality of the tidal volume calculation by this method, and the non conformance values are introduced as the quantitative parameters for the tidal correction effect of the two data of the quality control. In addition, the reliability of the tidal correction method is verified by comparing the seismic profiles before and after the correction, which shows that the method is of high practical value.
