Abstract: In the past seismic exploration in Qaidam Basin,large combination receiving has been often used in order to achieve the purpose of suppressing noise.However,as the exploration goes deeper,the disadvantages of the big combination gradually emerge.The single detector receiver can combine the channels in the post-processing of the data,which can not only suppress the interference but also eliminate the influence of statics in the large combinations,which is beneficial to the resolution, fidelity and imaging accuracy of the data.Based on the data of a survey line in the area of the peak mountain in the basin,this paper deals with and analyzes the trace combination,discusses the method,process and problems that should be paid attention to in the process of the trace combination,completes the function of the field detector combination,and shows the effect of the trace combination treatment.
