Abstract:

Spinning drop interfacial tentionmeter is used to study the influence of petroleum sulfonates on oil and water dynamic interfacial tention of the water and oil system from three oil-prducing regions in Shengli Oil field,that petroleum sulfonates impact the change of oil and water dynamic interfacial tention in the oil-prosucing regions is investigated from the three aspects of the time when oil and water interfacial tention gets to the lowest,the range of the stability value and the window width when the stability value is reached,which provides evidence for selecting petroleum sulfonates in different regions,and also,the relationship between injected ionic strenth and interfacial tention is stydied.

Key words: petroleum sulfonates, dynamic interfacial tension, tertiary oil recovery, enhanced oil recovery, surfactants
