| 摘 要： | 测量界面张力的方法很多，但最受关注的是旋转滴法。SVT20旋转滴界面张力仪是从德国进口的测量界面张力的一种新型仪器，使用方便，操作简单，但是由于在测量界面张力的过程中影响因素较多，没有得到很好的应用。从转速、液滴体积及光源亮度的选择、气泡的影响和排除等方面，对如何使用SVT20旋转滴界面张力仪准确测量界面张力进行了试验。通过试验得到测量界面张力的转速范围为5 000～8 000 r/min、注入液滴的体积为0.3～0.8 μL时测量结果准确。理论上界面张力越低的驱油剂其驱油效果应该越好，在室内对一些表面活性剂进行了界面张力测量，并做了相应的岩心驱替试验，试验结果与理论相吻合。
