摘　　要：利用电子显微表征的手段测定了胜利驱油剂SLS-5不同用量下形成原油乳状液的粒径分布情况,并考察了相应条件下的管式驱替效果。结果表明,达到最佳降黏率后,驱油剂SLS-5用量继续增加,驱替效果仍明显,发现高含量的驱油剂能形成粒径小且均匀的乳状液分散体系。The size distributions of the crude oil emulsion added with different amounts of oil displacement agent SLS -5 of Shengli Oilfield were determined with the technique of electron microscopy characterization, and the effect of tubular model displacement test at corresponding conditions was studied. According to the re- sults of test, the displacement effect can be improved significantly further when the concentration of oil dis- placement agent SLS -5 was increased even after optimum viscosity reduction rate is reached, and the reason for this is that the oil displacement agent of high concentration can form a uniform emulsion dispersion system of small particle size.
