Abstract: The present disclosure belongs to the field of geological exploration, and particularly relates to a seismic acquisition system based on a frequency domain expansion MEMS sensor, aiming at solving the problem that vibration frequencies exceed the frequency range of the MEMS sensor due to strong vibrations and cross coupling of multi-frequency signals usually occurring in well logging while drilling.
