Scanning device SD-Tubing

System for tubing and couplings installed on oil-production wells inspection.

Inspection can be performed directly on oil-production wells during the SD-Tubing descent and ascent inside string to a depth of 2 km or more.

Recording of the data is performed automatically in the "Timer" mode in conditions of ensuring of constant lifting speed of 1100 m/hr in certain time intervals. Based on inspection results tubes and couplings segments with damages and susceptible to damages are detected.
