摘要
火山岩是重要的油气储集岩之一,火山岩储集层的储集空间与火山岩岩相具有一定的相关性。露头及岩心实测资料研究表明,火山岩与围岩的沉积地层之间、火山岩各种岩性之间在密度、磁性、电性等岩石物性特征上均存在不同程度的差异。提出了以地震资料为主,地震与钻井及重、磁、电资料相结合开展火山岩识别与储集层预测的基本思路和技术方法。松辽盆地和准噶尔盆地的实践证明,该方法简单实用,效果良好,是目前火山岩识别与储集层预测的有效手段之一。
Volcanic rock is one of important petroliferous reservoir rocks. The reservoir space of volcanic reservoir has a certain correlation with volcanic lithofaeies. The research of the measured data from outcrop and cores shows that there exist differences of the density, magnetic, electrical and some other petrophysical properties between volcanic rocks and surrounding sedimentary strata and among various lithologies of volcanic rocks. In this paper, the volcanic rock identification and reservoir prediction are mainly based on seismic data and combined with drilling, gravity-magnetic-electrical prospecting data. Such a method is applied to the research of Songliao basin and Junggar basin, and improved that it is simple, practical and effective for application, being one of the effective means for volcanic rock identification and reservoir prediction at present.
