Abstract: Worldwide field applications have confirmed that steamflooding process is one of the effective means for improving" shallow heavy oil recovery. However,steamflooding process is more complicated than cyclic strain injection. The process is limited by reservoir geology and related to the process and time of steam stimulation tsteam quality, well patterns and injection—production strength. A more detailed discussion on conditionst time and its effective factors for steam stimulation—steamflooding conversion is based on an analysis of on—site data frewn Ditrict 9 and stcamflooding pilot areas in Kaiamay Oilfield using reservoir numerical simulation technology. Also, several ways for improving steamflooding efficiency are introduced.
Key words: heavy oil thermal recovery, steanflooding, condition and time for steam stimulation—steamflooding conversion
