Abstract: The reasons for increased formation of asphalt, resin and paraffin deposits in the fields of the Volgograd region are considered. It is shown that an important factor in the formation of paraffin, resin and asphalt in the affected fields is the formation of stable oil-water emulsions, which promotes active involvement of emulsified water in the sediment. A combined reagent, allowing to destroy oil emulsion and significantly reduce the amount of deposits on the surface of the oil field equipment is proposed.

Abstract: The paper analyzes the influence of the chemical composition of a group of four oils of Volgograd and Orenburg regions on their low temperature properties: freezing point and the tendency to form asphaltene-resin-paraffin deposits. It is shown that when studying the group composition it is important to consider not only the quantitative content of individual groups of compounds: paraffin-naphthenic and aromatic hydrocarbons, resins and asphaltenes in the oil, but also their mutual relationship, which can be determined on the basis of spectral coefficients. We found that deposits may grow in the presence of formation water. This is due to the amount of polar components-resins and asphaltenes - in the studied oil.
