【摘要】 本文从可控震源地震记录采集时使用的扫描信号参数出发,计算可控震源扫描信号,再将可控震源扫描信号进行自相关求出可控震源零相位子波。然后利用可控震源零相位子波,求出将零相位子波转化为最小相位子波的转换算子。最后利用该转换算子,将可控震源零相位子波转化为最小相位子波,实现了把可控震源零相位震源子波的地震记录转化为最小相位震源子波的地震记录的功能。更多还原

【Abstract】 Based on the scanning signal parameters which are used in Vibroseis seismic acquisition,the Vibroseis scanning signal was calculated,then Vibroseis zero phase wavelet was derived from auto-correlation of Vibroseis scanning signals. Then by utilizing the Vibroseis zero phase wavelet the conversion operator which converts the zero phase wavelet to minimum phase wavelet was derived. At last the conversion operator is used to convert the Vibroseis zero phase wavelet to minimum phase wavelet so that the function with which the seismic records with Vibroseis zero phase source wavelet are converted to seismic records with minimum phase source wavelet is realized.更多还原
