摘　　要：裂缝在火山岩储层中即是油气渗流的主要通道又能成为油气储存的空间，但火山岩裂缝的识别一直是个难题。本文针对火山岩油气藏的特点，研究和分析了该地区火山岩的测并响应特征。利用声波测井、中子测井和密度测并等方法对火山岩储层的构造裂缝进行了识别，并建立逐步判别函数识别裂缝，取得了很好的效果：Fracture in volcanic reservoir is not only the main passage,but aslo the storage space for oil and gas.It has been a difficulty to identify volcanic fractures.This paper analyzes the logging response characteristics of volcanic rocks in this area according to the features of volcanic hydrocarbon reservoirs.The structural fractures of volcanic reservoirs are identified with acoustic logging,neutron well logging and density logging,etc.A discriminant function is established to identify fractures which has got good result.
