摘　　要：井震联合标定地震反射目的层是构造解释、岩性反演中最基础的工作,是连接地震、测井数据的桥梁。建立目标层位与地震反射之间对应关系的工具是利用测井资料合成地震记录。从合成地震记录的原理及制作方法入手,指出影响井震联合层位标定质量的关键因素是正确处理测井数据和准确提取地震子波。利用杏树岗油田杏六东Ⅰ区块x5-4-135井资料和该区地震资料试验研究了测井曲线与地震子波对合成地震记录质量的影响。证明利用测井曲线提取确定性子波标定效果优于Ricker子波和统计性子波。The well-seismic integration calibration of seismic reflection layer is the basis for structure explanation and lithological inversion, and it is also the bridge between seisme and logging data. Drawing seismic record from logging data is the only tool to set the relation between target strata and seismic reflection. This paper starts from the theory and method of Synthetic Seismograms, then points out that the crucial factor influencing well-seismic integration calibration is the correct handling of logging data and the exact extraction of seismic wavelet. This paper takes the logging data of Xingliudong x5-4-135 and the seismic data test to study the influence of logging and seismic wavelet on Synthetic Seismograms quality. It is proved that extracting the determined wavelet calibration by well log is better than Ricker and statistical wavelet.
