摘　　要：本文用Zoeppritz方程对不同类型界面计算P波入射时P波与SV波的反射系数。通过分析，总结了P波与SV波位移反射系数随入射角的变化规律，用以指导P－SV转换波地震勘探的野外采集观测系统设计，并结合大庆某工区转换波勘探试验得出相应的结论。P-and SV-wave reflection coefficients at the incidence of P-wave have been calculated by using the Zoeppritz equation for different types of interfaces, By analysis, the variation of P- and SV-wave shift reflection cocfficients with incident angle is summarized. which is used to guide the design of field acquisition geometry for P-SV converted wave seismic survey. Also, some conclusions are acquired from the converted wave survey test conducted on a work arca of Daqing.
