| 摘 要： | 针对X油田渗透率曲线特征异常的情况,进行室内评价实验及矿物组成分析,结果显示岩样具有强水敏性。无因次采液(油)指数分析显示,水敏的存在使得此油藏在高含水期不能通过提液延长稳产期。建议采用水/气交替注入开发方式,并在注入水中加入2%的防膨剂。数值模拟结果证实该方案可行。

| Abstract: | Aimed at the abnormal features of permeability curve in X oilfield,it takes laboratory testing and mineral composition analysis. The result shows that the rock sample has strong water sensitivity. Based on the analysis of dimensionless fluid (oil) production index,it shows the oil reservoir can not prolong the stable production period by exact in the high water-cut stage because of water sensitivity. It suggests that using water/gas injection to improve oil recovery with adding 2% anti-swelling agent. And n... |
