RESEARCH OF THE EFFECTIVENESS OF OIL DEMULSIFIERS OF JARKURGON FIELD UNDER STATIC CONDITIONS

The aim of the work is to synthesize a demulsifier and determine its effectiveness in testing oil from the Zharkurgon field under static conditions. Hydrolyzed polyacrylonitrile was used to synthesize the demulsifier (DE-5). Under laboratory conditions, tests were carried out to determine the effectiveness of the synthesized demulsifier in the process of destruction of a stable water-oil emulsion of oil from the Zharkurgon field under static conditions. Good results on desalting and dehydration of typical oil were obtained using DE-5 in an amount of 30–40 g/t. With salt content of 505 mg/l in the oil, it was possible to desalt oil to 91.1%, with salt content of 775 and 1438 mg/l to 57.7 and 69.3% only. Increasing the demulsifier consumption above 40 g/t i reduces the residual salt content insignificantly, leaving it rather high (35–51 mg/l). The use of a demulsifier makes it possible to obtain oil with a salt content of 14 mg/l at a consumption of DE-5 in an amount of 20 g/t and 10% wash water.
