摘要
井下电视成像技术是基于数字视频体制的井下实时成像技术,成像测井的结果采用展开式钻孔柱状图方式表示,直观形象,便于分析。文章结合某移民迁建区中的滑坡工程勘察,对滑坡勘察中施工难度较大的钻孔采用井下电视成像技术进行分析,并结合钻探和地质调查成果确定滑坡的软弱滑动面的位置及形态特征,从而对滑坡的预防、预报和治理提供科学依据。
Downhole TV imagine technique is the real -time imaging of downhole video based on digital video, and the results of the imaging logging illustrated as unfolding drilling bore column are visualization and conveninent for analysis. In this paper based on the landslip prospecting engineering of a immigrant relocation area, the authors analysed the hole of constructing difficultly in the landslip prospecting with the method of downhole TV imagine technique, and confirmed the position and morphological characteristics of the weak and easily sliding layer, combined with the results of the drilling and geological survey achievement, which provides scientific basis for the prevention, forecast and treating of the landslip..
