基于地震数据的多道匹配追踪方法
摘要：
本发明公开了一种基于地震数据的多道匹配追踪方法，该方法包括：基于与一组地震道{f1(t),f2(t),…,fL(t)}中的单个地震道fl(t)相邻的该组地震道{f1(t),f2(t),…,fL(t)}中的其他地震道按照等式（2）对该单个地震道fl(t)进行多次分解以得到多个子波：其中，是第n次分解得到的且在该组地震道{f1(t),f2(t),…,fL(t)}内的所有地震道共享的基本子波，且为Morlet子波形式，L是该组地震道中地震道的个数，N是分解次数，n是1到N的整数，al，n是第n次分解得到的小波的振幅，R(N)fl(t)是最终的剩余地震道；其中，第n次分解包括：1）采用单道匹配方法计算一个初始的基本子波；2）采用多道匹配追踪方法对初始的基本子波进行精细计算；3）计算子波的振幅。
摘要（英）：

The invention discloses a multi-channel matching tracking method based on seismic data. The method includes the steps that based on other seismic channels adjacent to one single seismic channel fL(t) in one group of seismic channels {f1(t), f2(t), ... , fL(t)}, the single seismic channel fL(t) is decomposed many times according to the equation (2) so as to obtain a plurality of sub waves with the formula shown in the specifications, the sub wave with the formula shown in the specifications is obtained in the nth decomposing, is the basic sub wave shared by all the seismic channels in the group of seismic channels {f1(t), f2(t), ... , fL(t)}, and is in the mode of the Morlet sub wave, L is the number of the seismic channels in the group of seismic channels, N is the decomposing number, n is an integer from 1 to N, a{l, n} is the amplitude of the wavelet obtained in the nth decomposing, and R fL(t) is the final remaining seismic channel. The nth decomposing includes the steps that an initial basic sub wave is calculated with a single channel matching method; second, fine calculating is performed on the initial basic sub wave with the multi-channel matching tracking method; third, the amplitude of each sub wave is calculated.
