基于同相轴优化追踪的多次波匹配衰减方法
Multiple matching attenuation method based on optimized event tracing
摘要
Abstract
The paper introduces a multiple matching attenuation method based on optimized event tracing. Firstly, the meth-od uses multiple data predicted by SRME to generate multiple velocity spectrum, then gets travel time information of multiple event by event tracing technique. An optimized tracing is used to correct the errors of predicted multiples and then a short-time FK fan filtering is applied to attenuate the multiples. The matching attenuation is based only on travel time information of multiple, thus it can lower the requirement in the multiple prediction precision to a certain extent. Meanwhile, optimized event tracing can significantly improve the accuracy of multiple elimination. Model simulations and field tests show that the method has better multiple eliminating effect than conventional multi-channel Wiener filter methods and the mask filtering methods in parabola Radon domain.关键词
