Abstract
The study of the distribution of sediment formed from test oil on the sediment-forming surface at different temperature gradients was typical for resinous oils: the amount of oil sediment increased with decreasing oil temperature, and its maximum corresponded to temperatures closest to the pour point of oil. The properties and structure of oil sediments, which differed in sampling sites and methods, were greatly influenced by the thermodynamic conditions of sedimentation. In sediments taken directly from a well and formed in dynamic mode at higher temperatures for a short time period, the asphaltene content was lower than that in oil sediments from a receiving tank. In samples taken at the surface and formed at low temperatures for a longer period, the amount of paraffinic hydrocarbons was significantly higher than that in the sediments from the well.
