Abstract
For those who have access to seismic exploration principles and seismic data processing initially, there are essential difficulties. The difficulties include the great amount of seismic data, complicated processing procedure, long processing period as well as costly software and facilities for data processing. It is an important issue for how to make the beginners understand and master the fundamental procedures of seismic data processing easily, and how to make the processing procedures just look like to be done with microcomputer. This article is emphasized on virtual simulating seismic forward data processing based on LabVIEW platform and LabSQL. LabSQL is LabVIEW’s database kit, which is supplied by the 3rd party for accessing the database. It is beneficial for beginners to control processing procedure efficiently. This method is worth being promoted.

For the sake of accurate result, three times of dip move out (DMO) velocity analysis are necessary to eliminate the influence of stratigraphic dip move out
Summary
Seismic data processing refers to using the computer for processing seismic data, which is based on some principles of seismic These principles are seismic waves’ propagation theory, seismic exploration, a variety of methods of signal analysis and processing, etc. In this phase, seismic cross-sections, seismic velocity data and information can be generated. The information includes the characteristics of high signal-to-noise ratio, high resolution, high fidelity, and accurate imaging [1]. At present, softwares such as Promax, Focus, and Vista are used to process seismic forward data. E. Sun software based on the virtual instrument development platform of graphical programming. It is convenient for users to learn process seismic forward data only by connecting to the Internet through a browser
