N2 - The producing oil-field need the second/third time seismic data acquisition to evaluate the remaining production of crude oil. In the repeated data acquisition, the non-random well-pump noise affects the quality of seismic data. In order to know the characteristics of well-pump noise, we design a small single-point receiver array, and use this array to receive sufficient time duration of the typical well-pump noise. After analyzing the obtained well-pump noise, we find it has some characteristic differences with reflections, such as limited bandwidth, locating in low-frequency area, low velocity, dispersion and bad spatial correlation. Taking into account these differences, we propose an iterative method for well-pump noise attenuation in the time-frequency domain. By applying the proposed method to synthetic signal and real field data, we demonstrate the superior performance of our method.
