摘要:

采用全量程界面张力测量仪,研究了3种WPS对胜利油田3个采油区块油水体系的油水动态界面张力,从油水界面张力达到最低值所需的时间、稳定值的大小和时间窗口宽度的几个方面,考察了3种WPS对3个采油区块油水动态界面张力的变化情况,为不同采油区块选用WPS提供了依据。并研究了注入水离子强度与界面张力的关系,通过对注入水离子强度的调整,改善其油水界面张力。

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
