Abstract

The application of singular value decomposition (SVD) filtering is examined for attenuation of the ground-roll in land seismic data. Prior to the SVD computation to seek singular values containing the highly correlatable reflection energy, processing steps such as automatic gain control, elevation and refraction statics, NMO correction, and residual statics are performed to enhance the horizontal correlationships and continuities of reflections. Optimal parameters of SVD filtering are effectively chosen with diagnostic display of inverse NMO (INMO) corrected CSP (common shot point) gather. On the field data with dispersion of ground-roll overwhelmed, continuities of reflection events are much improved by SVD filtering than f-k filtering by eliminating the ground-roll with preserving the low-frequency reflections. This is well explained in the average amplitude spectra of the f-k and SVD filtered data. The reflectors including horizontal layer of the reservoir are much clearer on the stack section, with laminated events by SVD filtering and subsequent processing steps of spiking deconvolution and time-variant spectral whitening.

육상 탄성파자료에 나타나는 일관성 잡음인 그라운드롤을 제거하기 위해 특이값 분해 필터링의 적용성을 살펴보았다. 상관성이 높은 반사에너지가 요구되는 특이값의 계산을 위해 먼저 자동이득제어로 감쇠된 진폭을 보상하고 송수신점의 높이보정 및 풍화대 보정을 실시하여 장파장 시간차이를 제거한 후, 나머지 정적보정으로 단파장 시간차이를 완화시켜 반사면의 수평적인 연속성을 높였다. 특이값 분해 필터링에 적합한 입력인자(최대 주성분)는 공통중간점 자료에 수직시간차 역보정을 수행하여 얻은 공통발파점 자료에 대한 연속 테스트로 결정하였다. 그라운드롤의 시간에 따른 분산이 뚜렷한 현장자료에서 특이값 분해 필터링은 일반적인 기법인 f-k 필터링에 비해 반사신호의 왜곡없이 그라운드롤의 영향을 최소화하면서 주요 반사면들의 연속성을 향상시키는데, 이것은 진폭 빛띠에서 반사파의 낮은 진동수 성분들이 필터링 후에도 보존되었다는 점과 잘 상관되었다. 특히 특이값 분해 필터링을 거친 후 S/N 비를 높일 수 있는 자료처리(송곳곱풀기, 시간변화 빛띠흰색화) 과정을 함께 수행하여 겹쌓기한 결과 저류층을 포함한 주요 반사면들의 향상된 연속성과 분해능을 확인할 수 있었다.
