通过岩石薄片分析、岩心观察描述,运用成像测井分析技术、基于BP神经网络和判别分析方法的常规测井分析技术对火山岩单井岩性进行识别。运用三维地震分析技术追踪出长深1火山体、长深103火山体和长深1-1火山体,并建立了火山岩速度反演模型,分析各种岩性速度特征。以序贯指示模拟方法与协同克立金方法相结合,建立了火山岩储层三维岩相模型,为长岭气田火山岩气藏的进一步勘探与开发奠定基础。

The lithologies of volcanic reservoirs in a single well in the Changling gas field are recognized by means of thin section analysis,core observation and description,FMI analysis and conventional well log analysis based on BP neural networks and discriminant analysis method.Three volcanic bodies are identified through 3-D seismic analysis,and the velocity of volcanics is achieved by establishing seismic velocity inversion model.A three dimensional lithology model for volcanic reservoirs is constructed by integrating the sequential indicator simulation and the Co-kriging method,and on the basis,laying down a sound foundation for further exploration and development in the gas field.
