由于火山岩具有极强的非均质性，对其识别与预测是油气勘探的难题之一。此次油气勘探综合使用速度分析、地震反射特征分析、三瞬信息分析以及测井声波约束反演等技术和方法，有效地识别了三塘湖盆地4 类火山岩储集体：火山角砾岩、安山岩、玄武岩与凝灰岩。从而圈定出它们的横向展布，有效进行了裂缝储集体的预测，为火山岩油气藏的勘探开发提供了一定的理论依据和技术方法。

Due to the strong nonhomogeneity of volcanic rocks, related recognition and prediction technologies are still one of the problems existing in oil and gas exploration. Based on the analysis of velocity, seismic reflection characteristics and three-instantaneous information, combined with the techniques of constrained inversion of sonic logging, the reservoir rocks in Santanghu Basin are divided into four types, including breccia, andesite, basalt and tuff. The horizontal distribution is firstly determined. The prediction of fissure reservoir is effectively carried out, which provides theoretical foundation and technological methods for the exploration and development of volcanic reservoirs.
