摘　　要：断裂控藏历来是火山岩储层研究的重点与难点,学界普遍认为区域性断层在长距离大规模油气运移中具有决定性的作用,断层的封闭特性与作用部位,为储集层与生油层建立了丰富而又复杂的地质联系。笔者借鉴前人研究成果,通过对准东地区石炭系火山岩储层的综合研究,较为详细地阐述了准东地区由石炭系风化壳为主力储层,以上覆与基底不整合接触之二叠,三叠系沉积岩提供烃源岩,并由断裂控藏的断块型火山岩油气藏成藏模式。Regional faults are of great importance to large scale migration of petroleum and gas. A forming model for the fault block volcanic rock reservoir in the East Junggar Oilfield with Carboniferous crust of weathering as main reservoir and Permian and Triassic sedimentary rock as source rock is established based on comprehensive study of Carboniferous volcanic rock reservoir and previous data.
