| Abstract: | Through the medium of definite element technique of partial differential equation, this paper presents a solution of applying the definite element technique of scalar wave equation to the forward and inverse computing of seismic data. It discusses mainly the synthesis of zero shot-receiver distance as well as the synthesis of common shot point; 15° approximate and accurate migration of seismie data with varying velocities in all directions etc.Furthmore, the formular special for this computing purpose is given. |
