Abstract
A new inhibitor «NDP-22M» was developed to reduce the pour point of highly paraffinic oils and prevent the formation of asphalt, resin and paraffin deposits. The inhibitor contains a nonionic surfactant, a depressant agent and a solvent. The prepared inhibitor has the ability to reduce the pour point and viscosity of oil, as well as to prevent ARPD. The prepared inhibitor was studied on oil brought from the wells of the oil and gas production department of the production association «Azneft», «Oil Pipeline Administration». In this oil, the amount of paraffin is 10.8%. In the course of research, it was found that the effectiveness of adding 300 g/t of reagent to oil is 75%. Keywords: Precipitation; Depressant; Oil; Pour point; Paraffins; Depressive effect; Dynamic viscosity; Viscosity effect.
