Electro-magnetic Defectoscope

1. Electro-Magnetic Defectoscope is a down hole logging instrument which adopts the electromagnetic method.
2. It can be used to detect various damages such as corrosion, deformation, crack, fracture, holes in the down hole pipe string, and both the inner and outer metal loss of the string, to determine the thickness of down hole pipe string, and can correctly reflect the well sketch and the position of the down hole tools (collar, casing shoes, packers and valves, etc.).
It can be connected with LANDAU Cased Hole Logging Surface System to constitute a Casing Hole Imaging Logging System.
3. It sends the acquired measurement data to the surface system for decoding via the mono-cable. The decoded data is then processed by the surface software to generate the pipe wall thickness curve and the related 3D image, which will intuitively demonstrate the damage details of the downhole pipe string and the position of the downhole tools.
