Abstract: Based on the mechanism of volcanic eruption and the drilling and seismic data, the seismic response feature of volcanic facies in Santanghy basin, by which the favorable volcanic facies belts are attained. Through attribute analysis, pre-stack and post-stack inversions and fracture prediction approach, the favorable reservoirs are predicted in this paper. it is as a guide for further exploration of volcanic reservoirs in this area.

Key words: Santanghu basin, Carboniferous, volcanic facies, reservoir prediction, pre-stack inversion
