This article is devoted to the study of physical and chemical properties and composition of Sostinskoe oil field (wells № 8, 9). In the process of studying this problem have been put forward following tasks: 1) explore the basic physical and chemical properties of oil, such as density, viscosity, pour point (using appropriate methodologies Standard); 2) determine the fractional composition, water content, chloride salts, mechanical impurities; 3) determine the content of resins, asphaltenes and paraffin. The most important indicators of the quality of oil are the density and output fractions. Oil well no. 8 and no. 9 of Sostinskiy field are the density of the type 0 – particularly the lungs. The yield of light distillate fraction is high. It is in both cases more than 50 %. Content of mechanical impurities in the norm. According to the content of chloride salts of oil wells no. 8 belongs to the third group (up to 900 dm 3 GOST R 51858-2002). Because it contains a fairly large amount of water and chloride salts. The oil of Sostinskiy field of wells no. 9 refers to the second group (up to 300 dm 3 GOST R 51858-2002). Because it includes minimal amounts of water and chloride salts. The test samples of oils are oils of high viscosity. Pour point is high: +180 ºC (well 8) and +230 ºC (well 9). This is due to the high content of paraffin in them. In content resin-asphaltene substances sample data are resinous oil. The test samples of oils have a low density, high yield of distillate fractions; low water content, chloride salts and solids; high viscosity, high pour point, high paraffin content, and enough high-tar. Of these, it is recommended to receive commercial gasoline, diesel fuel, solvents, oil, liquid paraffin, petroleum oils, and waxes.
