Abstract:In order to suppress the regular interference and improve the useful signal,the field seismic data acquisition usually uses a variety of geophone array pattern to receive seismic wave. Since increasing channel capability in seismogram and length of spread,the apparent velocities of seismic useful waves are reduced in the faroffset traces and suppressed in different degree by geophone array,even more serious for highfrequency useful signals. The digital geophone can use single trace for receiving in the field and indoor receiver array can be implemented. In comparison with field geophone array,indoor array has his distinctive advantages. Based on the characters of field geophone array,analysis of data of single digital geophone receiving (5m group interval) and indoor array in Tongkou work area,the paper considered:①Different interference waves have different distribution features in time and frequency domains,small group interval is of advantage for separation and suppression of interference waves and large group interval is difficult to separate the signal from noise. ②The receiver array should meet the maximum space sampling condition and consider the influence of moveout of useful waves between the traces,and suppression of interference waves in maximum degree should be under the condition that the quality of received useful waves are not decreased;it is not complete that only relying to geophone array to suppress the ground waves,also should comprehensively consider various factors. ③When carrying out receiver array,such processing as eliminating coherent noises,adjustment of amplitudes and phases difference between traces,and moveout correction between traces should be strictly implemented for data.
