摘　　要：针对密度测井、纵波速度和横波速度曲线探测深度较浅,受井眼不规则影响比较严重的问题,为研究储层各属性的影响及与弹性属性间的关系,采用岩石物理模型对测井资料进行诊断和校正,提高测井曲线与地层信息的匹配程度。结果表明:经过岩石物理模型诊断和校正的测井资料能明显的提高测井资料的品质,根据校正后的资料才能正确的标定井震之间的关系,为地震解释和反演提供可靠的依据。It is vulnerable to be influenced by the irregular borehole for shallow detection depth when the curves of density, P-wave velocity and shear velocity are used. In order to study the influence of the reservoir properties and the relationship between the elastic properties and the reservoir properties, the authors diagnosed and corrected the logging curves using rock physical model so that it can reflect the real formation information. The results show that the logging curves corrected with the rock physics model can significantly improve the logging data quality of reproduction. It can establish the correct relations between the well data and the seismic data and check the results of inversion seismic.
