对河南油田三种原油中的有机酸和非酸含氧化合物进行了分离鉴定并研究了它们在碱水乳化中的作用。有机酸是引起各原油碱水乳化的活性物质,非酸含氧化合物本身无碱水乳化活性,但对有机酸的乳化活性有协同作用。
Organic acids and non-acid oxygenates in three crude oils of Henan Oilfield were isolated and identified and their role in alkaline water emulsification was studied. Organic acids are the active substances that cause the emulsification of the alkali oil of each crude oil. The non-acid oxygenated compounds themselves have no alkali-water emulsifying activity but synergistic effects on the emulsifying activity of organic acids.
