Abstract

The invention provides a vibroseis slip sweep data acquisition and processing method and device. The method comprises the steps that vibroseis vibration signal record data and all records of ground force signal data acquired based on predetermined sweep signal, the distance between vibroseis groups and slip time parameters are acquired by the preset vibroseis slip sweep acquisition method; data division is performed on the vibroseis vibration signal record data according to vibroseis group vibration starting time so that the single shot vibration record of the shot point corresponding to each vibroseis group is acquired; and deconvolution processing is performed on the single shot vibration record by using all records of ground force signal data so that the high-fidelity seismic single shot data record can be acquired. With application of the vibroseis slip sweep data acquisition and processing method and device, the problem that the high-fidelity seismic data cannot be acquired by the vibroseis seismic exploration correlation method slip sweep efficient acquisition technology can be solved so that the fidelity of the original seismic exploration data can be guaranteed and the construction efficiency of field production can also be guaranteed.

Description

technical field [0001] The invention relates to the technical field of seismic prospecting in applied geophysical prospecting, in particular to a method and device for acquiring and processing vibroseis sliding scanning data. Background technique [0002] Seismic exploration is a geophysical exploration method that uses the difference in elasticity and density of underground media to infer the nature and shape of underground rock formations by observing and analyzing the response of the earth to artificially excited seismic waves. important means of mining. The process of seismic exploration usually consists of three stages: data acquisition, data processing and seismic data interpretation. Data acquisition mainly means that in the field observation operation, multiple geophones are arranged at equal intervals along the seismic survey line to receive the seismic wave signals excited by the source. Geological language—seismic profile or structural map, weakening interferenc...
