Multivariable method to analyze velocity of seismic wave

In this paper, the author analyzes the factor of the velocity from time to depth, and points out the limitations of the traditional methods. Considering the influence of multi-dimensional speed ,The paper gives conceptions of velocity component and its coefficient and composes a function to analyze velocity with multi-factors by using methods of multinomial imitate, Kriging and weighted average method in data fusion to contrapose these shortcomings. It is easier to calculate and materialize with discrete velocity component and its coefficient, and favorable to transform time to depth automatically and increases its precision also. Through the contrast of two exploration stages in the same district, good application effect has been proved.
