THE ANALYSIS OF THE EFFICIENCY OF REMOVING SULFUR-CONTAINING COMPOUNDS FROM OIL AT THE «BELKAMNEFT» PSP
The problem of improving the quality of crude oil by neutralizing or removing hydrogen sulfide and mercaptans during the processes of extraction, collection and preparation of oil is considered. Currently, for the removal of sulfur-containing compounds present in oil, the following control methods for their functional orientation are known: removal of hydrogen sulfide from well products; prevention of the formation of biogenic hydrogen sulfide; prevention of hydrogen sulfide corrosion of oilfield equipment; prevention of the formation of deposits of iron sulfide in the reservoir and downhole equipment. The article discusses the advantages and disadvantages of various methods of combating hydrogen sulfide and mercapts. Based on the studies of the content of these compounds in oil delivered to the Belkamneft PSP, it was found that in order to improve its quality indicators, the most optimal method is to use chemicals that neutralize hydrogen sulfide at a dosage of 200 g/t, since this is due to the ease of implementation and small capital expenditures.
