摘　　要：通过对合成记录制作的一般方法进行分析,结合研究区实际地质、地震资料,提出合成记录的制作在层位标定中的实用优化方法,强调了子波的提取方法和子波相位引起的偏差。该方法应用在辽河油田新开—董家岗地区这个地震资料品质较差的区块,使得层位标定的精度较常规方法有了较大的提高。By analyzing general methods used in compiling synthetic record, taking consideration of the seismic and geological data of the study area, a useful optimal method, which emphasized the wavelet extraction method and the deviation caused by wavelet phase, was presented to make synthetic seismic records. With the application of this method to Xinkai-Dongjiagang area, Liaohe Oilfield, where the quality of seismic data was relatively poor, making the accuracy of stratigraphic unit demarcation highly increase compared with general methods .
