FIELD: oil industry.
SUBSTANCE: invention relates to development of oil and gas deposits and can be used for prevention of various deposits in oil-well tubing. Method of using heat-insulated flexible load-carrying polymer pipe for tubing operations involves placing on winch drum, lowering into well on tubing string (TS) against stop in well equipment, securing in well head, shutting off top end of tubing string, wherein extracted fluid during transportation may be heated by electric heating elements, embedded into wall of said pipe.
EFFECT: longer service life and well flow rate, as well as increased safety of its operation.
