摘　　要：随着火山岩油气藏的发现,火山岩作为油气储层的重要性已引起勘探开发工作者的更多重视。火山岩石物性和储集空间具有特殊性,一些原本比较成熟的理论方法和技术手段已不适用火山岩储层预测。研究发现,火山岩储层与非储层之间存在差异,应灵活运用现有的技术手段进行火山岩储层的预测。对辽河坳陷黄沙坨地区沙三段粗面岩储层地震预测结果表明,综合运用精细构造解释、多井约束波阻抗反演、基于模型的储层参数反演、电阻率差比法裂缝预测等实用技术,在研究区实现了粗面岩储层的地震预测及描述,其结果与钻井实测数据比较符合。Along with more and more volcanic reservoirs are discovered, volcanic rock is attached with more importance as oil and gas reservoir. Because of some particularity of volcanic rock in physical properties and reservoir space, some traditional methods and technologies suitable for reservoir prediction may be unsuitable for volcanic reservoir prediction. The volcanic reservoirs should be predicted by agilely using the existent technologies. The seismic prediction of trachyte reservoir in the third member of Shahejie Formation in Huangshatuo Oilfield of Liaohe Depression was made. The practicable seismic technologies such as fine structure interpretation, multi-well constrained impedance inversion, model-based reservoir parameter inversion and fracture prediction with resistance difference and ratio are reasonable in prediction and description of the trachyte reservoirs. The predicted result is coincident with drilling data.
