Abstract：Based on analyzing the theory of refractionand tomographic static corrections and through ap-plication of them to real 2-D and 3-D seismic data, the paper resulted in such conclusion:the refrac-tion static corrections can better solve the long andshort wavelength issues of static corrections;whilethe tomographic static corrections have such ad-vantages as free from relying on refractor, the mod-e1 is suitable for majority of exploration environ-menu, easy operation of computational approachand adaptable to any geometry patterns. The paperalso pointed out the disadvantages of the approa-ches and precondition of usage. For the demands oftwo Venezuela projects, the good results have beenachieved by integrating refraction with tomograph-is static corrections to compute datum statics, SOl-ving the difficulties that are unable to be solved bysingle approach of static corrections.
