Abstract: With respect to current situation of heavy oil steam- flooding development and characteristics of the reservoir, adopting laboratory physical simulation technique and numerical simulation technique, and applying mechanisms of intermittent flooding, nitrogen plug steam flooding and active agent flooding, the comparison of development effects and study of operation manners are made, production and development index of 10 years afterward is predicted, their economy evaluations are conducted. Through field experiment, these results have shown to be as guides for improving current steam flooding operation and increasing oil recovery rate.

Key words: heavy oil, steam flooding, activity, plug flooding, mechanism, prediction, economy evaluation
