【摘要】 徐家围子火山岩天然气藏是目前在我国东部发现的存在于火山岩层中的最大天然气藏。随着勘探的深入,火石岭组火山岩将是今后重要的勘探层位。通过对最新三维地震资料的分析,认为现今火石岭组火山岩沿徐西断裂分布的特征主要是沙河子期徐西断裂改造的结果。火石岭组火山岩喷发的受控机制为地幔上涌,导致岩浆沿地壳深层的断裂向上喷发。更多还原

【Abstract】 Xujiaweizi gas reservoir is the largest gas volcanic reservoirs in the eastern China.The Huoshiling volcanic rocks will be an important exploration target.By means of the latest 3D seismic data,we consider that the distribution of the Huoshiling volcanic rocks along the Xuxi fault is the product of the Xuxi fault reconstruction at the Shahezi period.The Huoshiling volcanic eruption is crystal magma migrated upward along deep faults.更多还原
