摘要
The single-channel seismic data from marine regional geological survey have some problems such as time shift between traces, recording delay due to changed seafloor depth, and pre-recording due to software. The authors tried to remove the time shift by using the wave static correction method, which is based on the cross-correlation function. Several parameters are very important to the effect of the static correction. This paper classified the strata into three types based on their structures. Tests of key parameters were made on different structures, showing good results of static correction. The choice of proper parameters for different structures are discussed in this paper, and some useful suggestions are put forward for the purpose of making good use of residual static correction.
