摘　　要：介绍了多分量技术在四川盆地广安构造勘探中的初步应用情况,包括野外采集、处理和解释。在多分量采集和处理获得较好资料的基础上,进行了纵波和转换波(P-SV波)的层位匹配,转换波层位标定,制作压缩剖面。通过对纵波和转换波剖面的对比分析及纵波和转换波(P-SV波)的联合反演,提取了纵横波速度比、λρ和μρ等属性参数,对须六段地层进行了储层预测并取得了初步成效。This paper introduces the application of multi-component technology in the exploration of Guangan structure. On the basis of quality data from proper data acquisition and processing, we performed horizon matching between P- and converted-waves, horizon calibration for converted-waves, and construction of compressed sections. Attributes such as velocity ratio of P- and S-wave, λρ and μρ were extracted by comparison between P-wave and converted-wave sections and joint inversion of P-wave and converted-waves. The method has been applied in the prediction for reservoirs of the sixth segment of the Xu Formation.
