海上压缩感知地震采集技术研究与应用
Research and application of offshore compressive sensing seismic acquisition technology
摘要
Abstract
By random sampling,compressive sensing seismic acquisition can significantly improve seismic ac-quisition efficiency and reduce seismic acquisition costs.Therefore,a design method and workflow are proposed for an offshore compressive sensing seismic acquisition geometry.Firstly,in response to the alias and difficulty in anti-alias reconstruction in the evaluation of offshore compressive sensing seismic acquisition geometry and field data processing,a frequency-wave number domain weighted anti-alias data reconstruction method is put forward.Then,the developed efficient offshore compressive sensing seismic acquisition technology and data re-construction method are applied to a real survey of a volcanic buried hill in the South China Sea.A wide azimuth ocean bottom nodes compressive sensing acquisition geometry is also designed.The quality,feasibility,cost re-duction and efficiency improvement of the compressive sensing acquisition geometry are evaluated by the meth-ods including data reconstruction.The designed compressive sensing acquisition scheme is successfully imple-mented in the real survey in the South China Sea,obtaining the first independently designed and implemented offshore compressive sensing acquisition field data in China.The application results show that,under the prem-ise of reducing costs and increasing efficiency by 25%,the compressive sensing acquisition in this survey achieves comparable results to the conventional acquisition,providing effective support for the subsequent re-search and promotion of efficient offshore compressive sensing acquisition technology.关键词
