摘要/Abstract

摘要： 针对火山岩这一特殊岩性体埋藏深、岩性复杂、成层性差、平面分布规律复杂，储层油、气、水分布规律复杂等特点，应用地震叠后频率衰减属性和分频属性对松南气田火山岩储层含油气性进行纵向和平面上的预测，主要研究松南气田白垩系营城组火山岩储层含油气情况。实践证明，预测结果与实际情况符合率较高，有效地对营城组火山岩储层空间展布特征进行了识别。通过检测地震反射波的振幅衰减梯度变化和高频段吸收衰减特征，可检测其含油气性，为开展营城组火成岩储层的油气藏描述工作奠定了基础。

Abstract: This paper,aiming at studying the oilgas in the Cretaceous Yingcheng formation volcanic reservoir in Songnan gas field,which is characterized by deeply buried depth,complicated lithology, poor stratification, involuting horizontal distribution,and oilgaswater distribution in reservoir,applies seismic frequency attenuation and division frequency to predict the oil gas in the volcanic reservoir both vertically and horizontally.The result shows a highly consistency with the practice. And the spatial distribution of Yingcheng formation volcanic has been effectively identified.Oil gas can be reflected by detecting the amplitude attenuation gradient change of seismic reflection wave,and high frequency absorption attenuation,underpinning the oil gas reservoir description of Yingcheng formation volcanic reservoir.

Key words: Songnan gas field, volcanics, oil gas detection
