摘　　要：火山岩储层横向变化大,具有很强的非均质性,一般的反演方法对火山岩进行储层预测难度较大。由于谐振法完全依赖于地震资料,对于火山岩这类储层横向变化较大、井间变化较快、无法得到精确模型的储层,利用谐振法油气检测技术可以克服反演中受模型影响带来的误差。为此,利用谐振法技术对火山岩储层含气性进行了叠前谐振法油气检测。检测结果与钻井结果符合较好,符合率为80%。The volcanic reservoir was changed greatly in horizontal direction,its heterogeneity was serious,thus it was difficult for volcanic reservoir prediction by using ordinary inversion method.Because the resonance method wholly depended on seismic data,exact model could not be obtained for volcanic reservoirs with big lateral changes and interwell changes.The resonance method for hydrocarbon detection could be used to avoid errors induced by the model.The technique of hydrocarbon detection is applied for volcanic reservoir prediction for pre-stack resonance detection.The detection result is consistent with that of well drilling,its coincidence rate is up to 80%.
