摘要

A heating method for an oil production well provided with a sucker rod, deep well pump installed inside flow string characterized in arranging inside the flow string the sucker rods of the deep well pumps which are hollow with insulated heating cable inside therein and uniformly heating produced fluid over a distance from well head to lower end of flexible insulated heating cable up to temperature 2-60°C exceeding temperature of paraffin melting in produced fluid, wherein produced liquid heating is carried out directly through hollow sucker rod string during reciprocation thereof inside flow string.
