Abstract
This study was aimed at investigating the chemical composition and commercial properties of crude oil mined at the Ichyodinskoye field. A graph of atmospheric distillation was constructed. The content of commercial fractions was determined from the curve of true boiling temperatures. The obtained data were analysed according to the hydrocarbon composition of the gasoline fraction, which was found to comprise alkane, cycloalkane and aromatic compounds in the amount of 53.12%, 27.21% and 18.45%, respectively. In terms of sulphur, the oil mined at the Ichyodinskoye field is considered to be low-sulphur, thus belonging to the1st class. A distinctive feature of this oil consists in its inability to form stable emulsions due to a low content of solid paraffins in its composition. In the study, artificial emulsions of the oil and deposit water with a watercut value of 30% were obtained. The developed emulsions were investigated by analysing the process of gravitational settling for 120 min at a temperature of 50 °C, as well as using a LUMiFuge device. It was found that the oil mined at the Ichyodinskoye field is low-sulphur and light, containing a high content of light distillates. It is known that low-sulphur oils are safer for field equipment in terms of corrosion, thereby decreasing costs of supplying oil to consumers. Such oils are a high-quality and promising raw material for the production of oil products.
