| 摘 要： | 稠油油层能否成功点燃是火驱成功的关键,因此预热时间显得尤为重要。而多孔介质条件下,计算加热不同半径所需时间十分困难。根据新疆油田火驱矿场油藏条件,建立了一种等效简化模型,可以计算加热不同油层半径所需的时间,对二者关系进行定量刻画。通过现场验证,该方法与实际监测结果符合率高,加热时间绝对误差0.6 d以内。 |

| Abstract: | Successful in-situ combustion of heavy oil reservoir is the key by fire-flooding process,which focuses on the preheat time.In porous media,the time computation for preheating radius-varied reservoir appears very difficult.According to the fire-flooding reservoir conditions of Karamay oilfield,this paper develops a simplified equivalent model,by which the preheat time and the preheat radius of heavy oil reservoir can be calculated and described quantitatively.The case study indicates that the result given by this model is almost the same with real data,with absolute errors of preheat time and preheat radius are less than 0.6 d and 0.02 m,respectively. |
| Keywords: | Karamay oilfield heavy oil reservoir fire flooding preheat time preheat radius |
