Small-size electromagnetic flaw detector EMDS-3

Designed for flaw detection and separate determination of pipe wall thickness in wells with multi-column construction. Features and advantages -Detects defects such as cracks, breaks, corrosion and mechanical wall abrasion intervals, explosive perforation zones and filters, as well as disconnections in couplings; -determines thickness of three inner pipes (including tubing) separately for each pipe (after machining) without removing the tubing; -allows to investigate the well structure: to determine the position of couplings, to get a complete picture of the location of all pipes by depth, the depth of column shoes, packers, valves, etc. With the help of the processing programme a scheme of the well structure with defects, couplings and shoes is built, as well as a scheme of signal isolines with increasing measurement time.
