<p>The invention relates to the oil industry. The inventive method for heating a well with the aid of a deep-well pump is carried out by supplying electric power through hollow pump rods to tubing strings which, being heated, transfer a heat to an oil fluid and is characterised in that the extracted fluid is heated by means the total length of a flexible heat source (heating cable) to a temperature which is by 2-60 °C higher than the paraffin melting point starting away from the well mouth to the lower end of the heat source (heating cable), which is placed inside a string of rods which transfer a reciprocal motion to a piston (plunger) of the deep-well pump, wherein the extracted fluid is heated directly though the string of hollow rods.</p> |
