摘要
Abstract
During the direct computation of vp/vs by ray-path elastic impedance, the analytic expression is high-power function consisted of the ratio of two elastic impedance, which has poor stability and antinoise ability, so it is limited for application. Therefore, one modified ray-path elastic impedance need to be developed to make the computation of elastic parameters more stable. Through using binomial theorem quadratic to the ray-path elastic impedance formula, the ray-path elastic impedance was expressed into a function of P-wave impedance and S-wave impedance. By experimental analysis and error derivation,analytical formula of P-wave impendence,S-wave impendence and other elastic parameters were given. The application in some offshore area obtained good results.关键词
