摘要
地震数据采集中,激发因素、采集方法、采集时间等因素的不同,使得地震子波振幅、频率、相位存在差异,对地震资料的处理和解释都会产生不利影响。对地震资料作子波一致性处理,可为波场分析、储层反演及油气预测提供高品质的地震资料。本文基于VSP测井和三维地震资料连片处理中子波整形的原理和方法,从地震数学模型出发,对子波整型方法的处理进行改进,经过模型试算和实际应用,取得了一定的效果。
The wavelet amplitude, frequency and phase are different because the data acquisition is in different time, method and also, the data has different source properties, that adversely affect seismic data processing and interpretation. Waveform consistency is an important factor to the accuracy of wave field analysis, reservoir inversion and hydrocarbon prediction. Based on the principles and methods for waveform consistency shaping in VSP logging and merging processing of 3D seismic data, the paper improved the waveform shaping method using seismic mathematical model. We have got good result in model spreadsheet and practical application.
