针对大庆油田绝大多数井都缺少横波测井资料的现状,在分析目前计算横波速度理论模型的基础上寻求横波与其他测井项目的相互关系,选取了与横波速度曲线关系密切、曲线精度和稳定性较好的补偿声波时差和归一化之后的自然电位曲线,采用统计回归的方法建立了研究区横波速度模型.通过与实测横波速度曲线及实验数据的对比,证明该模型精度较高,能够达到岩石物理分析的要求,在喇嘛甸油田500口生产井应用效果较好.%Aiming at the present situation that most wells in Daqing Oilfield lack the data about shear wave acoustic log, based on the analysis of the current theoretical model used for calculating the shear wave velocity, and seeking the correlation among shear wave and other logging projects, a compensating acoustic travel time which has close relationship with shear wave velocity and relatively good accuracy and stability and a normalized SP curve are selected, and then a wave velocity model for the region of interest is established through the statistical regression. Through the comparison of measured shear velocity curve and experimental data, it is proved that the accuracy of this model is relatively high and can satisfy the requirement of petrophysical analysis. A relatively good application effect has been obtained in 500 production wells in Lamadian Oilfield.
