以Zoeppritz方程为准,通过模型数据分析,分别对比了Shuey三项式、Shuey二项式、Aki公式、Connolly公式、小角度Connolly公式、射线阻抗公式的精度。认识到在实际应用中一定要注意各近似公式的适用条件。使用Connolly公式、Shuey三项式时,要将入射角控制在50度以内;使用Shuey二项式和小角度Connolly公式时,要将入射角控制在30度以内;使用Aki公式和射线阻抗公式时,需分析实际资料的适用性。
Based on the Zoeppritz equation, the precision of Shuey’s triad formula, Shuey’s binomial, Aki’s formula, Connolly’s formula, small-angle Connolly’s formula and the formula of ray impedance were compared respectively by the model data analysis. Realize in practical application must pay attention to the applicable conditions of the approximate formula. When using the Connolly and Shuey trinomials, the angle of incidence should be controlled within 50 degrees. When using the Shuey binomial and the small angle Connolly formula, the angle of incidence should be controlled within 30 degrees. When using the Aki formula and the formula of the radiation impedance , Need to analyze the applicability of actual data.
