摘　　要：通过在两维纵向非均质正韵律物理模型上开展的三元复合驱油实验研究，探讨了注入方式对驱油效果的影响。找到了几种较佳的注入方式，可在化学剂用量不变的条件下使原油采收率提高２％左右；The injection schedule of ASP flooding solutions for ASP programs in Daqing is studied by physical simulation on two dimensional vertically heterogeneous normal rhythm models. 9 injection modes of varrying number, composition, size and order of injection of slugges are designed and tested to investigate the effects on the oil recoveries from the models of increasing size of or polymer concentration in main ASP slug, introducing polymer pad or secondary ASP slug, and injecting polymer and A+S separately. The most effective and beneficial injection schedul is shown to be: polymer pad+main ASP slug+secondary ASP slug+protective polymer terminal.
