Determination technological parameters of wellbore heat treatment for a deep pump with hollow rods
One of the main complications, being during the exploitation of production wells, is the formation of asphaltene-resin- paraffi deposits (ARPD). In conditions of low inter-cleaning periods of well work (less than 30 days) and high strength of structural-mechanical bonds in ARPD, formed in tubing above the pump, the most economically and technologically expedient way to combat complications are fl shing-out of well. The calculation of the thermal state of a well equipped with a sucker rod pump during heat treatment through hollow rods with a bypass clutch are considered in the paper.Based on the results of the calculations, it was noted that the temperature of the injected agent (hot oil or water) aff s the temperature of the inner wall of the tubing lower than the coolant fl w rate.
