Сomposition and properties of oil sludge formed during oil production
The paper describes the results of studying the composition and properties of four samples of oil sludge obtained during oil production in the oil field. The process of separating the hydrocarbon (organic) part of oil sludge into separate fractions was carried out, and their properties and group hydrocarbon composition were studied. The content of metals in oil sludge was studied. The composition and properties of mechanical impurities found in oil sludge were studied.
