FIELD: physics.
SUBSTANCE: group of inventions relates to field geophysics, particularly to devices and methods for non-destructive testing of technical state of casing ferromagnetic pipes of wells. Locator of perforated holes and connecting sleeves of casing ferromagnetic tubes consists of apparatus for determining position of instrument in space, control microcontroller, induction locator of couplings, radar perforation holes, wherein collar locator comprises one inductive converter arranged in the centre of the device, which is comparable in diameter to the device housing, and the perforation hole locator comprises n devices by means of nonmagnetic inserts of induction converters with sizes of magnetic conductor shoes, comparable to sizes of perforation holes.
EFFECT: technical result is increase of accuracy and reliability of indication of perforated holes of casing pipes.
