Fine processing and interpretation technology and application of seismic data in low SNR area*

For a low SNR and fracture region in the piedmont zone of north Tarim Basin, fine processing and interpretation and comprehensive evaluation of geological data were carried out, giving priority to favorable areas for oil-gas exploration. Through high-precision static correction processing, pre-stack time migration, reservoir prediction, gas bearing analysis and other technical means, it had further determined the tectonic characteristics, put the trap distributions into practice, predicted the favorable reservoirs, given favorable exploration areas, and put forward recommended well locations.
