Key words: oil mixture, depressant additives, pour point, effective viscosity, shear stress.
Results of researches of possibility of improvement of refrigerant flowing properties of the West Kazakhstan oil mixture transported on the main Uzen – Atyrau –Samara pipeline are given in the article. The optimum heating temperature of the oil mixture and putting additives is 80-90 °C. Mixing Western Kazakhstan oil with low-paraffinic oils Emba and Aktobe fields increases its susceptibility to heat treatment (60 °C) and the action of depressants.
