In order to understand the seismic response characteristics of Huoshiling Formation volcanic reservoir in Lishu fault��guide the interpretation of seismic data and identify the reservoir period��the authors build the volcanic model combing with the drilling information and geological recognition��and do forward modeling to volcanic seismic response using nonstationary random medium modeling��Through forward modeling calculation��the authors analyze the seismic response characteristics of each layers and sedimentary facies zone from shallow to deep�� which provides the evidence for clearing the volcanic reponse regularity��testing the veracity of geological and seis mic interpretation model and deeping the knowledge of reservoir-forming rule of volcanic rocks in studied area��
