摘要：

本文以克拉玛依油田5—8区二叠系佳木河组火成岩为例,对火山角砾岩、玄武岩及流纹斑岩,用交会图进行识别。同时给出了各类火成岩的体积密度、中子孔隙度、有效光电效应和吸收截面指数及铀、钍、钾含量值的变化趋势。

Abstract:

Since the volcanics has a quite complicated composition,it is difficult to evaluate the content of different minerals in vlcanics by log data.The volcanics of the Jiamuhe Forma-tion of Permian System,5-8 distrcts,Karamay Oilfield is divided into volcanic breccia,basalt and rhyoporphyry based on the data of cross section,and distinguished using cross-plots.The paper also provides the values of density,neutron porosity,cross section index of effective photoelectric absorption and uranium,thorium,potassium contents.
