Abstract

Abstract: The production data estimated in Liaohe oilfield were summed up and analysed by using mathematical statistics，and two simplified methods are presented, i. e. ,the methods of injection-production characteristic curves and oil/steam ratio decline curves, for estimating the recovery factor at the stage of cyclic steam injection for thermal recovery of viscous oil.

Key words: Thermal recovery of viscous oil, Stage of cyclic steam injection, Recovery factor, Estimating method
