【摘要】：時(shí)移地震中兩次地震資料采集時(shí)間不同,記錄的潮汐量不同,導(dǎo)致兩次資料中出現(xiàn)一定時(shí)差,并且采集資料時(shí)基準(zhǔn)面不統(tǒng)一,所以時(shí)移地震資料處理中潮汐校正成為必要環(huán)節(jié)。本文介紹一種時(shí)移地震中基于潮位值預(yù)測(cè)的潮汐校正方法,并采用水深數(shù)據(jù)快速檢驗(yàn)該方法計(jì)算潮汐量的合理性,也引入非一致性值作為質(zhì)控兩次資料潮汐校正效果的定量化參數(shù)。此外,也通過對(duì)比校正前后地震剖面,驗(yàn)證了該潮汐校正方法的可靠性,說明該方法實(shí)用價(jià)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.
