摘　　要：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。In order to fully use the good horizontal tracking ability of reflection data and the high vertical resolution of log data which indicate the physical properties by well directly and accurately, the authors put forward the joint inversion methods for velocities of P and S wave and density respectively to the seismic-geological models of thick and thin reservoirs. The tested results of theoretical models show that the inversion methods are feasible and effctive.
