The paper describes the study of demulsifiers for effective dewatering of crude oils in different Kazakhstan oil fields, including the fields Aryskum, Kumkol and Sarybulak, based on physicochemical characteristics of these oils. It was shown that by a set of parameters the most efficient were the demulsifiers presenting composite reagents based on block copolymers of ethylene oxide, propylene oxide and ethoxylated phenol-formaldehyde resins.
