影响地震道多尺度反演效果因素分析

测井、地震资料联合地震道多尺度反演方法是笔者近年来在地质理论指导下研究出的通过小波变换多尺度思想进行地震道反演的方法。理论和实际资料的处理表明,这种反演方法具有收敛速度快、反演精度较高、适应能力较强的特点。为了搞清各种因素对测井、地震资料联合地震道多尺度反演效果的影响规律,通过改变各种参数用上述方法分别对理论模型和实际资料进行了试算和处理,得到了一些有意义的结果,为该方法的进一步完善和拓宽其应用范围提供一点思路和方向。

AN ANALYSIS OF FACTORS AFFECTING SEISMIC TRACE MULTI SCALE INVERSION

Guided by recent geological theory and the idea of wavelet transform multi scale analysis, the authors formulated the method of logging and seismic data unit seismic trace multi scale inversion in which the logging and seismic data are used to perform seismic trace multi scale inversion. Theoretical and practical data show that this inversion technique is characterized by quick convergence rate, high inversion precision and high capacity of accomodation. To detect factors affecting seismic trace multi scale inversion, the authors used theoretical models and real seismic data and reached some important conclusions on the basis of changing input parameters and applying seismic trace multi scale inversion technique. The purpose of the research work is to improve the result of inversion.
