A depressant has been developed to reduce the pour point of highly paraffinic oils. The pour-point depressant contains a non-ionic surfactant, a pour-point reducer and a solvent. The prepared depressants reduce the pour point and the viscosity of oils. The depressor properties of the prepared additives have been investigated for oils of production wells No. 20, 53, 266 and 444 of the OGPD named after N.Narimanov, "Azneft" PU. The paraffin content in these oils is 6.0-20.1%. The highest depressor effect value, as well as the viscosity effect, is noted for oil in well No. 266. A depressant in an amount of 0.02% and 0.04% of oil contributes to the depressant effect, 27-28 degrees C and 30-31 degrees C respectively. Viscosity effect for this oil with addition of certain additives at an amount of 0.04% of oil at 35 degrees C and 40 degrees C, makes 48.29-51.80% and 51.40-55.71% respectively. It was noted that the amount of paraffin, contained in oil, is of great significance in achieving high values both for depressor effect, and for the viscosity effect.
