摘　　要：侯春会，伍先运，王克协．利用斯通利波衰减反演储层渗透率．测井技术，１９９７，２１（３）：１６２～１６６流体井孔中的柱状声源被同种流体饱和的孔隙介质包围。以该声源激发的声波场理论为基础，采用分波分析的方法研究复波数平面内极点留数对应的斯通利波。建立了利用斯通利波幅度衰减反演储层渗透率的线性化最小二乘反演模型。利用不同储层条件下的合成全波数据，对反演渗透率结果的稳定性、收敛性及误差作了细致的考察。反演结果表明：这是一种简单、有效的地层渗透率求取方法。Based on the theory about the wave field stimulated by cylindrical acoustic sources in the borehole which is filled with fluid and is surrounded by porous media fully saturated with the same fluid, the characteristics of stoneley wave which corresponds to the pole in complex wave plane are studied with wave component analysis method. A linear least square inversion method is put forward to evaluate the formation permeability from the attenuation of stoncley wave. With the synthetic full wave data derived from various parameters of different reservoirs, the stability, convergence and errors of the inversion are analysed in detail. It is proved that this inversion is simple and effective for evaluating formation permeability.
