Abstract：The development of such interference waves as refraction,surface wave and sideswipe is very severe in the seismic data acquired in Qaidam hasin,and using receiver array for depression of interference waves achieved good effects.For that reason,it is necessary to understand the role of seismic array for wave receiving again.In comparison with the case of receiver array in A work zone of Qaidam basin,the paper introduced an analytic method using F-K filtering and average array effect of CMP bins based on receiver array and concluded following knowledge:①the receiver array-based anti F-K filtering method can conveniently simulate the seismic records of receiver array with different patterns,array length and directions,providing the foundation for selecting appropriate array pattern;②the different geometry and array patterns have different CMP average array effect in 3D seismic survey,so,it should use different array patterns in different 3-D seismic geometry,and design of array pattern should be carried out by CMP bin azimuths and statistic results of receiver distribution;③in the area of strong interference,in order to improve the S/N ratio of seismic data,it should increase the number of receivers and geophone interval appropriately to depress interference as far as possible.
