Research on Application of the Television Image Logging Technique in the Englineering Test Borehole

Abstract

A whole image of a reconnaissance well with acoustic time, acoustic amplitude and video can be obtained by an image logging apparatus. The results (feature dip/strike and azimuth, joint density analysis, synthetic cores, feature stereograms, rose diagrams, deviation plots of borehole) of image logging are displayed in the form of well explained figures, intuitionistic, vivid and easy to be analyzed. Image well logging technique has played an important role in oil and gas exploration, but its application in construction engineering is still in its initial testing phase. The hardware constitution and the basic principle of RG image logging apparatus system are simply introduced, and its application effects in transmission cable tunnel project are also displayed in this paper
