Research On Application Of The Television Imaging Log Technique In The Engineering Test Borehole

A whole image of a reconnaissance well with ultrasonic time, ultrasonicamplitude and video can be obtained by an imaging log apparatus. Theresult of imaging log is, displayed in the form of well column figures,intuitionistic, vivid and easy to be analyzed. Imaging well log techniquehas played an important roll in oil and gas exploration, but its applicationinconstructionengineeringisstillinitsinitial testingphase.Thehardwareconstitution and the basic principle of RG imaging log apparatus systemare simply introduced, and its application effects in water conservancyengineering are also displayedin thispaper.
