摘要:
野外地震资料采集中,检波器的各种组合通常作为压制规则干扰、突出有效信号的重要手段,但野外检波器组合在压制干扰波的同时也压制了有效信号。采用数字单点检波器很容易在室内实现接收道组合,且效果优于野外组合。在理论分析的基础上,针对川西高密度试验线,利用单点多分量数字检波器、5 m道距5 m线距接收的地震资料Z分量进行了室内不同方式的组合试验。研究表明,采用合适的组合方式,在基本不影响资料分辨率的同时,可有效提高数字检波器接收信噪比,达到甚至超过常规模拟检波器接收效果。
Abstract:
To suppress the regular interference,improve the useful signal and increase the signal to noise ratio of raw data,a variety of geophone array pattern is usually used to receive seismic wave in field seismic data acquisition.Although the pattern can suppresses interference waves,it damages desired signal.Adopting the single point digital geophone,the indoor array for unite single trace data can easily be carried out,and is superior to the field geophone array.Based on theoretical analysis,a variety of indoor overlapping data has been carried out by combination with the data of 5 m group interval single point digital geophone received in work zone of western Sichuan.The study results show that a good indoor overlapping technique for single-point digital geophone can increase the signal to noise ratio of raw data,and attain or exceed the effect of seismic data acquisition of normal analog geophone meanwhile the data resolution is not basically affected.
