Development of AO NPF GITAS with PAO GAZPROM
is designed to control technical condition of steel tubing and pump and compressor string in unkilled gas and oil wells of single-column and columned constructions, perforation interval specification.
Features and Advantages
- the possibility of two pipes defectoscopy and thickness gauging performance with pipe wall thickness change value and their transverse and longitudinal defects*;
- the possibility of columned well construction determination (up to 4 pipes);
- high-sensitive thermometer and GK presence for according to depth.
Apparatus composition
- digital downhole tool with two centering devices, surface interface block with power supply, software, control and monitoring station;
- operates with computer of Notebook type (mobile variant) or in the composition of any software-controlled logging station.
