Abstract: In view of the current situation in China where Distributed Acoustic Sensing (DAS) technology is widely applied in downhole seismic exploration but insufficiently utilized in surface seismic exploration, this paper first analyzes the recording effects based on straight fiber optic cable surface seismic experimental data, and discusses the causes of DAS directional sensitivity phenomena in surface seismic exploration. Secondly, the basic principle of Helically Wound Cable (HWC) in improving DAS directional sensitivity issues is elaborated, and the response characteristics of seismic waves with different incident angles under various winding angle conditions are analyzed. The ability of this technology to improve DAS directional sensitivity characteristics is further verified through HWC surface seismic acquisition experiments, enhancing the receiving effect of DAS technology in surface seismic exploration. Finally, combined with production experience, several suggestions are proposed for the further development of DAS technology in surface seismic exploration.
