基于压缩感知的非规则地震勘探观测系统设计与数据重建
Irregular seismic geometry design and data reconstruction based on compressive sensing
摘要
Abstract
This paper proposes a method of irregular seismic geometry optimal design and data reconstruction based on compres sive sensing.To optimize the irregular geometry design in seismic data acquisition,the method selects sampling points one by one according to a greedy sequential strategy,which could decrease the maximum cross-correlation value of the sensing matrix.To reconstruct seismic data effectively,the method solves the underdetermined sampling matrix through an L0 and L1 regularization mixed iterative algorithm.When applied to the irregular seismic geometry design in the TFT exploration area,the method uses the maximum and the minimum group intervals as constraints to overcome the limitation of the receiver cable length.The results show that the proposed method provides an effective way for the development of high-density 3D seismic exploration.关键词
