From the view of theory and practice, it presents that laser output power P, scanning velocity V and the diameter of faculae E are fundamental technological parameters in treatment with laser.

The results show that were different from power density and scanning velocity its in the surface of hardening layer microstructures and properties also different from, when power density W>4.

The optimal distance among casing connection and probe can be further researched and the relationship between arrayed probes and scan speed can be demonstrated more clearly from this arrayed system.

Taking account of the result and computational efficiency, we put forward a method in which migration velocity analysis is realized by velocity scanning using ray tracing in common mid point (CMP) gathers in this paper.

The process of calculating the velocity includes three times migration velocity scanning and eight types of velocity calculating,which is a gradually convergent process.

First, the geometry of the scan mode is depicted, and the scan angular velocity and scan angular scope are determined according to the desired imagery patch size and cross-range resolution respectively.
