为了充分利用测井资料较高的纵向分辨率及其反映井壁周围物性直接准确的特点和地震资料良好的横向可追踪性，针对厚储层和薄储层地震—地质模型分别提出了利用测井和地震资料联合反演纵横波速度和密度参数的方法。理论模型的计算结果表明，反演方法是切实可行的 In order to make full use of the high vertical resolution of well logging data and the direct and accurate characterization of physical properties around wellbore and the good lateral traceability of seismic data, aiming at the seismic-geological models of thick reservoirs and thin reservoirs, Method for joint inversion of P- and S-wave velocity and density parameters with well and seismic data. The calculation results of the theoretical model show that the inversion method is feasible
