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; *The tool can be operated through a triple-core cable KGZ-70-180 (length up to 5000 m). Recorded signal parameters time, amplitude Information input, output and processing methods a PC digital one Information presentation method a hole sweep one Maximum operating pressure, MPa 60 Maximum operating temperature, °C 120 Logging speed, m/h 60÷120 Tested casing diameters range, mm 73÷250 Downhole tool dimensions, mm: diameter (without centralizers) length 42 2000 Number of core used 3 Weight, kg up to 18 
• 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).
