基于成像测井的火山岩结构分析

Structure Analysis of the Volcano Rock on Borehole Imaging

常规测井资料对火山岩的结构信息反映较弱,而成像测井资料却能准确、直观地反映岩石的结构、构造特征。鉴于成像测井的这一特点,本文介绍了火山岩的几种常见结构,从成像测井图像中提取反映岩石结构信息的纹理特征,分析了火山岩不同结构的纹理特征响应,利用交会图对火山岩的不同结构进行分析。实验表明,成像测井图像的纹理特征能够较好地分析火山岩的结构。

Conventional logging data weakly reflect the structural information of the volcano rock,however imaging logging data can reflect the structure and structural feature of rock.This paper describes several kinds of common structures of the volcano rock,it extracts the texture feature of rock from borehole imaging images which can reflect the structural information of rock,and it analyzes different texture characteristic response of the structure of rock,It analyzes different structures of the volcano rock base on the crossplots of texture feature.Experimental results show that the texture feature of borehole imaging images can effectively analyze the structure of the volcano rock.
