Abstract：After many years' exploration and development,the exploration environment around the maturing field became complicated,the reason is mainly increasing many mechanic equipments,especially the pumping units,the mechanic vibration of which has larger impact on seismic exploration.Facing with the situation,the paper emphatically analyzed in detail the feature of noise interference produced by pumping unit,analyzing the geometric feature from two aspects of propagating and spatial feature and analyzing the dynamic feature of noise interference of pumping unit from the aspects of amplitude,frequency and phase feature for the data acquired from the spreads with different receiving array.The above analyses have some guiding meaning for studying the corresponding noise-suppressed method.
