FIELD: chemistry.
SUBSTANCE: group of inventions is related to oil industry and intended for workover, geophysical and thermal and hydrodynamic surveys of oil, gas and other wells using coil tubing and for well intervention. The unit (Fig. 1) includes a transportation basis 1 with two outriggers 12, the operator's cabin with control system 9, a drum 2 with drive 4, coil tubing 3, a winder 10 for winding of coil tubing to the drum, an injector with jigging blocks 5 with a guider 11 installed before it, the injector drive 6, sealing and BOP equipment 7 connected to the well Christmas tree 8 and a logging module 14, at that the drum drive is a power drive unit, the guider is made as a roll, coil tubing (Fig. 2) is a polymer-coated steel tubing; at the unit there is an installed pump 13 and a speed sensor measuring speed of the tubing feed to the well, two delivery force sensors and a metre measuring length of the tubing in the well, at that the above sensors, a temperature sensor and a well-pressure gage, the third delivery force sensor, a gamma-activity indicator, an accelerometer, a collar locator and the metre measuring length of the tubing in the well are connected to the control system, at that the logging module includes a temperature sensor and a well-pressure gage, a collar locator, a gamma-activity indicator, an accelerometer and the third delivery force sensor.
EFFECT: provision of workover, geophysical and thermal and hydrodynamic surveys of oil, gas and other wells.
