摘　　要：火山岩岩性的准确识别是火山岩储层描述与评价的基础。通过对三塘湖盆地火山岩测井相应特征进行的分析归纳,建立了火山岩岩性识别流程。首先利用取芯井段标定准确岩性,然后利用交会图法、模糊聚类分析法以及微电阻率成像测井资料对研究区内储层岩性进行综合识别。将研究区岩性划分为火山熔岩、火山碎屑岩、火山碎屑沉积岩和沉积岩4大类、11小类。通过22口井的资料进行处理验证,岩性识别符合率平均达84.7%。Accurate identification of volcanic rocks in volcanic reservoir description and evaluation is an important basis.Santanghu basin by volcanic rocks of the corresponding log analysis of the characteristics of induction,the establishment of a volcanic lithology identification process.Firstly,accurate calibration of core lithology well section,then use the intersection graph,fuzzy clustering analysis,and micro-resistivity imaging log lithology of the study area,a comprehensive identification,the study area was divided into the volcanic rock lava,pyroclastic rocks,volcanic rocks and clastic sedimentary rocks 4 categories,11 categories.22 wells through the processing of data validation,lithology identification consistent with the average rate of 84.7%.
