基于三维模型数据的地震振幅补偿处理技术的保幅性分析
An analysis of the amplitude preservation of seismic amplitude compensation processing technology based on 3D model data
摘要
Abstract
Relative amplitude⁃preserved processing of seismic data is the basis of lithologic reservoir exploration.However,the systemat⁃ic theoretical and experimental analysis of relative amplitude preserved⁃processing for seismic compensation techniques remains very in⁃sufficient.In this paper,taking spherical spreading compensation and surface consistent amplitude compensation technique as an exam⁃ple, the authors present the theoretical analysis method and evaluation standards.At first,the relative amplitude⁃preserved properties of the two methods are analyzed theoretically,then the seismic amplitude compensation methods are applied on the 3D numerical model,fi⁃nally the compensated results are compared with the original numerical model,and thus the effects on the relative amplitudes of the two compensation methods can be quantitatively analyzed.Theoretical analysis and numerical results indicate that spherical spreading com⁃pensation and surface consistent compensation methods do relatively well for amplitude preservation.关键词
