摘要借鉴花岗岩区单元超单元填图理论方法，通过对乌增苏辉长岩体岩石学、岩石化学、微量元素、稀土元素等特征的研究，将岩体划分为四个单元。
4 . according to lithochemistry properties of volcanics , starting with logging evaluation mechanism , a method of identifying lithology by radioactive logging is set up ; on basis of core analysis data , log response of reservoir petrophysical properties is analyzed , thus providing basis for evaluating reservoir using logging data ; on basis of testing data , combining with log imaging around wells , comprehensive classification criteria of volcanic reservoirs and porosity interpretation model are established . 5
4 ，根据火山岩岩石化学特点，从测井评价机理出发，建立了利用放射性测井资料识别岩性的方法;以岩心分析资料为基础，分析了储层物性的测井响应特征，为利用测井资料评价储层奠定了基础;以测试资料为依据，综合井周成像测井资料，建立了火山岩储层的综合划分标准及孔隙度解释模型。
