Abstract: Deep-well survey method is first applied to observe the seismic wavelet signals energized by multi-type explosives and charges. The paper made a great deal of quantitative and qualitative analysis and directly calculated correlation between the energy of seismic waves and amount of charges while carrying out some investigation upon the law of attenuation in low subweathered zone and high-velocity zone. On such basis, the new reflection and transmission coefficient spectrum theory based on the fundamental unit of a single individual thin layer and synthetic method with regard to geological settings were applied to make and analyze record of the model. The optimum energized powder-type and content were determined, in addition to a great deal of in-depth argumentation over the design, which applied maximum receiving parameters. Significant effect has been achieved using this approach in the Practical application in Tarim basin.
