EFFECT OF OIL TEMPERATURE ON PARAFFIN WAXING OF OIL FIELD EQUIPMENT

摘要

Analysis of paraffin-waxing of oil field equipment at West Siberian oil fields has shown that the number of wells troubled by wax deposits has been going up every year. Wax deposition causes fall in oil recovery and entails additional cost for deposit removing. Many researchers have studied the distinctive features of the process of wax deposit formation from model solutions [1-3]. Analysis of the obtained data has revealed that they are highly inconsistent even for such simplified systems as artificial mixtures of wax and solvent. That is why, to prevent resin-wax deposits (RWD), it is essential to study their formation process in real oils. Until now, this process has been poorly studied because of wide diversity of properties and compositions of oils.
