摘　　要：地震勘探领域,可控震源已广泛应用于各种陆地地震勘探项目中。互相关检测技术是可控震源地震数据处理的主要方法,针对常规可控震源地震数据互相关检测方法,当在采集过程中出现强、中脉冲噪声时,会在相当长的时窗内造成噪声水平提升的问题,采用阈值多级中值滤波可控震源数据检测方法,通过对实际可控震源地震资料的处理,结果证明利用阈值多级中值滤波可控震源数据检测方法,有效实现了可控震源地震数据的检测,与传统的检测方法相比数据的信噪比得到了明显提高,说明了此方法的有效性。Vibroseis has been widely used in various land seismic exploration projects in seismic. The correlation detection technology is the main method of vibroseis seismic data processing. The problem for the conventional vibroseis seismic data correlation detection method is that the impulse noise will enchance the level of noise during acquisition.We utilize the method of Threshold Multilevel Median Filter in seismic data detection for vibroseis.Through processing of actual vibroseis seismic data,we can make an conclusion that the mehod effectively realized the detection of vibroseis data.Compared with conventional detection method,the SNR of data has been improved significantly.It illustrates that the method is effective.
