Abstract：Attributes analysis and design of 3-D geometry are an important link of seismic data acquisition, among which the reasonableness of offsets distribution in attributes analysis of geometry is one of most important parameters. Common-used seismic data acquisition software don't provide distinguishing standard of quantitative analysis. For that reason,starting from the quantitatively distinguishing standard of offsets-distributing reasonableness and optimum design of geometry parameters, the paper presented that using the size of changing rate of adjacent offsets within a bin to judge the uniqueness of offsets distribution and minimizing the variance of offsets-changing rate for objective function of optimizing geometry parameters, which provided new method and tool for optimum design of geometry to a certain degree and in part links.
