摘　　要：研究了胜利油田孤岛稠油及胜坨高凝油中沥青质在驱水驱油方法中的乳化性能。结果表明,所研究的原油中的沥青质均含有乳化活性组分,它与碱液间均能形成低界面张力,有利于碱水驱油。The emulsitymg properties of asphaltenes in Gudao heavy crude oil and Shengtuo high freezing crude oil with alkaline system were examined. The results showed that asphaltenes separated from the studied crudes all contain the emulsifiable active components which form the lower interfacial tension with alkaline solution and favour for alkaline flooding.
