Abstract：The piedmont structures at the southern margin of the Junggar Basin are complex, with great oil-gas exploration potential. Well GT1 has achieved high-yield industrial oil-gas flows. In contrast, the target formations of the Gaoquan Anticline are deeply buried, the reservoir is thin, and small faults have developed. Consequently, surface seismic data has a limited resolution. In response, efforts are made to achieve technical breakthroughs in walkaway vertical seismic profile (W-VSP). Three-component W-VSP data are collected. Comparative data analysis shows that the resolution of W-VSP data is significantly higher than that of the surface seismic data and small faults and thin re-servoirs are thereby clearly identified. This research not only provides a basis for analyzing the distribution of main oil-gas target formations and the types of oil-gas reservoirs of the Gaoquan Anticline but also offers experience for W-VSP application at Xinjiang Oilfield.
