| Abstract: | In this paper, production stabilizing pattern diagram of waterflooding oilfield is set up based on production experience of waterflooding oilfields in and out of China. The 4 factors which affect recovery percent of recoverable reserves at the end of stable production period are summarized as: oil production rate of recoverable reserve during stable production period, reservoir geological and physical properties, oilfield adjustment measures and increase of recoverable reserve. According to the pattern, data from 70 waterflooding sandstone oilfields in China and 13 waterflooding sandstone oilfields in Former Soviet Union are gathered. Through multivariate regression, the calculation formula of recovery percent of recoverable reserves at the end of stable production period are obtained for each oilfield. Among them, two formulae have better consistency. |
