Vibroseis coding random aliasing efficient seismic data acquisition method

The invention provides a vibroseis coding random aliasing efficient seismic data acquisition method, which comprises the following steps of: grouping vibroseis according to the limitation of the construction range of the vibroseis and the number of the vibroseis in a single day; respectively designing a coding aliasing scanning signal of each seismic source according to the requirement of a geological target on a frequency band and the number of seismic source groups; loading the coded aliasing scanning signal to a corresponding vibroseis box body and a seismic instrument, and carrying out random aliasing seismic data acquisition; seismic data before or after correlation of the vibroseis are obtained, and sorting is carried out according to the coded aliasing signals; preprocessing the sorted vibroseis seismic data, and respectively carrying out seismic section superposition and imaging processing; and combining the coded aliasing seismic imaging sections to obtain a final seismic section.
