Abstract
The present application provides a method and device for determining overall metrics of seismic geometry repeatability, wherein the method comprises: selecting baseline geometry and monitor geometry; matching shot-receiver pairs of the baseline geometry with shot-receiver pairs of the monitor geometry to obtain multiple matching relationships; calculating overall geometry repeatability of each of the multiple matching relationships according to a predetermined calculation formula for multi-trace geometry repeatability, to obtain overall geometry repeatabilities corresponding to the multiple matching relationships; taking the minimum value among the overall geometry repeatabilities corresponding to the multiple matching relationships as overall repeatability metrics between the monitor geometry and the baseline geometry. In the embodiments of the present application, by using the above method, the aim of accurately determining repeatability of multiple shot-receiver pairs in time-lapse seismic acquisition can be achieved, and thus the monitoring efficiency of seismic geometry repeatability can be improved.
