is designed for open hole and casing inner surface imaging to evaluate roughness, corrosion, holes, slots and casing-collars.
Features and Advantages
• accurate visual image of the casing string inner surface for its technical condition evaluating;
• high-degree precision of the defects’ identification by its types and evaluation of its sizes;
• real time information displaying to provide an improved operativeness of information visualization;
• improved reliability of information due to its presentation in different modes, which are selected by the processing programs on PC;
• borehole size changing in the investigation interval;
• combinability with digital stations (of GECTOR type).
*The tool can be operated through a triple-core cable KGZ-70-180 (length up to 5000 m).
