The pre-stack time migration and velocity analysis methods on common
scatter-point (CSP) gathers are based on pre-stack Kirchhoff time
migration. The concept of equivalent offset provides a new idea for
the research of seismic pre-stack migration and velocity estimation.
In this paper, according to the theory of the equivalent offset,
we derive the travel-time equation of CSP gathers, introduce the
related pre-stack time migration method and discuss velocity analysis
methods based on the CSP gathers, and point out the advantages of
CSP methods over conventional methods. Processing of a model example
and field seismic data show the validity of CSP pre-stack time migration
and the velocity analysis methods based on it.
