FIELD: oil-and-gas industry.
SUBSTANCE: proposed plant comprises short and long tubing, eccentric stabiliser arranged at long tuning, parallel anchor, downhole instruments located above and under packer, geophysical cable fixed at eccentric stabiliser by locks and cable tight adapter. Note here that eccentric stabilisers feature hemispherical grooves with chamfers and are nor attached to tubing. This allows it to turn about axis but it is locked by rings in lengthwise direction. Top and bottom downhole instruments are interconnected via one geophysical cable while well filter is connected to packer. Short tubing is passed via eccentric guides by hemispherical chamfered grooves.
EFFECT: higher reliability, simplified assembly.
