Method and device for determining overall measurement of seismic observation system repeatability

A method and device for determining an overall measurement of seismic observation system repeatability, wherein the method comprises: selecting a baseline observation system and a monitoring observation system (101); matching offset pairs from the baseline observation system with offset pairs from the monitoring observation system to obtain multiple matching relationships (102); respectively performing calculation on the multiple matching relationships according to a preset multi-track observation system repeatability formula, so as to obtain overall repeatability values of the observation system corresponding to each of the multiple matching relationships (103); using a minimum value of the overall repeatability values of the observation system corresponding to each of the multiple matching relationships as an overall measurement of repeatability between the monitoring observation system and the baseline observation system (104). By using the above method, the situation in which offset pairs are different and matching cannot be confirmed between the baseline observation system and the monitoring observation system can be solved, and the aim of accurately determining repeatability of multiple offset pairs in time-lapse seismic acquisition can be realized, thus increasing the monitoring efficiency for repeatability in seismic observation systems.
