Abstract：There are different types of strong interference in seismic acquisition in complex surface areas,which affect seismic data quality.Single-point acquisition,that is point-receiver or/and point-source acquisition,in complex surface areas always generates strong short-wavelength noise such as ground roll,multiple refraction,sideswipe,and so on.The noise almost submerges seismic signals and makes data signal-to-noise ratio (SNR) very low.Receiver array or/and source array acquisition can suppress this kind of interference and improve data SNR,but it filters out high frequency components and causes waveform distortion.To solve this problem,we should consider the receiver array and source array at the same time.Therefore we propose an ideal of receiver-array and source-array matching.In order to determine optimal matching receiver-and source-arrays,we fit out different response curves for noise suppression based on a new theory formula rather than conventional theory formula.We finally extract optimal matching quantitative formula for a pair of optimal matching receiver-and source-arrays.The proposed approach is not only tested and verified by a software system,but also achieves good results in the practice.
