Research of multiple elimination method in inverse wavelet domain

JIN De-Gang, CHANG Xu, LIU Yi-KeInstitute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100029, China  
SRMA(Surface Related Multiple Attenuation)algorithm has two steps including prediction and subtraction. In subtraction, it is very important to attenuate multiple events effectively and preserve primary events under the situation when multiple events cross with or overlap on primary. Under some reasonable hypothetic conditions,the error of inverse wavelet which is caused by non-orthogonality is nearly Gauss distribution. Based on the conclusion, we adopt a new method to eliminate multiples, which is to use the statistic character of error, obtain inverse wavelet's estimation, correct misshaped inverse wavelets for non-orthogonality in inverse wavelet domain by the estimation. The method mainly has four steps. Firstly, after getting predicted multiples, we use adaptive subtraction algorithm to eliminate multiples and get some inverse wavelets corresponding to every trace in one shot gather, then construct inverse wavelets domain by those inverse wavelets. Secondly, use median filtering method to get inverse wavelet estimation in inverse domain. Thirdly, correct the misshaped inverse wavelets in inverse domain by the inverse wavelet estimation. Finally, use new corrected inverse wavelets as new filters to eliminate multiples. It is proved that the method is valid and can keep continuation and amplitude of the primaries after simple and complex model testing.
