Model-based relative-amplitude-preserved estimation methods and application of seismic processing technology
摘要
Abstract
Now, there are few effective methods in the relative amplitude preserved estimation of seismic processing technology. It is difficult to evaluate the amplitude-preserved feature using real seismic data, which are affected by many factors such as noise, surface condition, and so on. Based on model data, four kinds of amplitude-preserved estimation methods are proposed, including amplitude statistics curve, residual difference, amplitude ratio and AVO attribute - preserved method. In addition, using model data, the amplitude-preserved features of some key processing techniques are estimated by means of methods mentioned a-bove. By the estimation result, processing parameters and flows can be optimized for geometrical spread compensation, predictive deconvolution and surface consistent amplitude compensation techniques. In consequence, the research is very useful for the improvement of amplitude-preserved of seismic processing results.关键词
