摘　　要：在前人的研究成果基础上建立了含气饱和砂岩和含水饱和砂岩模型,利用反射系数公式对两组模型进行各向异性分析,结果表明利用P-SV波方位各向异性分析,可以区分含气饱和砂岩与含水饱和砂岩。On the basis of research findings by predecessors, models of gas - saturated sandstone and brine - saturated sandstone were built, and the azimuthal anisotropy was analyzed by using the reflection coefficient formula. The results show that the azimuthal anisotropy of P - SV wave can be used to distinguish the gas - saturated sandstone and brine - saturated sandstone.
