针对西部三塘湖盆地马朗三维连片区块石炭系火山岩埋藏深、岩性多样、成层性差、平面分布规律复杂等特点,从火山岩储层特征分析入手,以火山岩储层预测为主线,从单井地震相属性分析出发,井震结合,建立起主要目的层的火山岩有利储层与地震反射特征的对应关系,并充分运用多属性分析技术,通过提取石炭系目的层的三瞬属性、频率衰减梯度及反演等属性,综合利用多技术手段来预测研究区火山岩有利储层的分布规律,最终建立起一套适用于西部深层火山岩的储层预测的属性分析技术系列.%The Carboniferous volcanic rocks in the Malang 3D merged block in Santanghu Basin are characterized by deep burial depth, diversified lithology, poor layered property and complicated distribution pattern. This paper analyzes the characteristics of volcanic reservoirs and single well seismic facies based on logging and seismic data. The corresponding relationship between favorable volcanic rock reservoir and seismic reflection has been established. Distribution of favorable volcanic rock reservoirs is predicted by comprehensively using multiple techniques such as picking up instantaneous seismic attributes, frequency attenuation gradient and seismic inversion of the Carboniferous objective interval. A series of attribute analysis techniques has been established for prediction of deep volcanic rock reservoirs in western China.
