【摘要】 这里介绍一种应用地层倾角测井、声波测井、密度测井资料制作井旁二维人工合成记录的方法，其内容包括：（1）把声波曲线和密度曲线生成的声阻抗曲线作基础道；（2）按地层倾角和CDP间距把该基础道向左、右分别外推两道，形成一个5道的地质模型；（3）进行断层、不整合修正后，利用褶积正演产生井旁二维人工合成记录。这种井旁二线人工合成记录较以往的一耸入工合成记录有以下优越性：①增加了构造倾角、断层、不整合信息；②可提高钻井资料与地震剖面间的桥式对比精度。该方法在大庆油田探区断陷盆地一些探井上应用，见到良好效果。更多还原

【Abstract】 We give a method for synthesizing borehole-side 2D seismogram with the useof dip log, acoustic log and density log data- The method consists of the followingsteps:. The acoustic impedance curve that is derived from acoustic log and densitylog curves is taken as a basic trace-. According to formation dip and CDP interval, two traces are extrapolated atthe each side of the basic trace to form a five~trace geological model.. Borehole-side 2D synthetic seismograms are produced by making convolutionafter fault and unconformity are revised carefully.Compared with one-dimensiona1 synthetic seismogram, the borehole side 2Dsynthetic seismograms have the following superiorities: 1)added dip, fault and un-conformity informations, and 2) irnproved correlation between drilling data andseismic section. This method was applied to exploratory borehole data in faultedbasin in Daqing area,with satisfactory result.更多还原
