地震数据保幅处理质量监控方法
|
摘要
地震叠前反演,要求做到保持地震振幅的相对变化关系,因此在处理过程中的质量监控就变得尤为关键.我们主要方法是选取若干关键处理步骤作为质量监控的控制点,由点到线,到面对每一个控制点进行质量监控,保证每一个处理步骤能够最大限度地保持振幅的相对变化关系.经过实际应用见到初步效果,今后考虑处理解释一体化的方法来定量反应处理步骤对地震振幅的影响.
It is important to preserve relative relationship of seismic amplitude for seismic inversion-oriented processing,so quality control is crucial during seismic processing.The method we used is to pick up some crucial steps as control points and quality control is applied from points to lines and from lines to plane to every control point. The method can make sure that every step will preserve the relative changes of seismic amplitude by the greatest extent.As the practice works well,the influence of processing step on the seismic amplitude should be reflected quantitatively by combining process and interpretation in the future.Most of the methods mentioned in this paper are qualitative or semi-quantitative and not involved in seismic interpretation.Quantitative or interpretation involved method must be more effective,which will be developed in future.
