FIELD: oil and gas production.
SUBSTANCE: method of fluid flow heating in well includes preparation procedure on determination of required length and capacity of heating cable. Heating cable is descended into the tubing, heated and thermal condition is adjusted with the aid of heating cable operation time change for maintaining a constant temperature of fluid flow in well head. In the course of preparation procedure the capacity of heating cable is selected depending upon well parameters according to the provided mathematical expression. Heating cable consists of coaxially arranged isolated heating elements, additionally includes a lay from steel zinc-plated wires located over the central heating element that is covered by intermediate shell, armouring and outer shell. Note that the direction of armouring lay is opposite the direction of steel zinc-plated wires lay.
EFFECT: increase of well average flow rate and prevention of hydrate-paraffin deposits formation.
