基于3D Curvelet变换的频率域高效地震数据插值方法研究
Efficient seismic data interpolation using three-dimensional Curvelet transform in the frequency domain
摘要
Abstract
We analyzed the theoretical feasibility that certain effective frequency components could characterize the original data.An efficient three dimensional (3D)seismic data interpolation method in the frequency domain is proposed for application to 3D irreg-ular seismic data,which uses the spectral conjugate symmetry property of seismic data and the projection onto convex sets method based on 3D Curvelet transform.This method performs interpolation on frequency data halved in size.Synthetic data and field data tests demonstrated that the proposed method could effectively improve the efficiency while guaranteeing the interpolation perform-ance.In particular,the interpolation efficiency can be increased by approximately one time when the maximum effective frequency equals the Nyquist frequency.关键词
