Abstract
In order to find the perfect timing for the fracturing of polymer flooding in type Ⅱ reservoir so as to reach the greatest increase in recovery factor, cluster analysis and multi-factor deviation analysis combined with single factor variable are applied, and statistics on fracturing effect of type Ⅱ reservoir is done. The best fracturing timing for different production wells during polymer flooding in type Ⅱ reservoir has been obtained. The result shows that for well-connected and well-developed production wells, the best timing for fracturing is the stable water cut period when the water cut is below 80% ; for well-connected and poor-developed wells, the best timing is the stable water cut period when the water cut is below 85% ; for poor-connected and well-developed wells, the best timing is . When the water cut is below 80% and injection intensity is over 10 m3/ (m ? D) ; for poor-connected and poor-developed wells, the best timing is when the water cut is below 85% and injection intensity is over 10 m3/ ( m ? D).关键词
