摘　　要：通过数值模拟对胜利油田郑408-20井组的火驱现状进行分析,并预测未来5 a开发动态指标。计算结果表明:郑408-20试1油层较厚,注气量偏小,顶部油层由于气体的上浮作用气蹿现象更严重,造成了单井产量较低;通过增加注气量、转湿、控制水气比等开发方案的调整,水气比为1.3 kg/m3时,预测5 a后地层压力约为9 MPa,地层温度有所降低,水蒸气把已燃区内的热量带到了燃烧前缘,火烧前缘已经接近生产井,累积产油量为30.86 kt,采出程度达到14.59%。In-situ combustion status of Zhen 408-20 well group in Shengli Oilfield was analyzed using numerical simulation.The development dynamic indicators for 5 years were forecast.The results show that the oil reservoir of Zhen 408-1 test well is thick and the gas-injection rate is low.The phenomenon of gas jump is serious at the top,so the single well production is lower.After adjusting the development plan by increasing air injection rate,shifting to the wet combustion with water-gas ratio of 1.3 kg/m3,5 years later,the formation pressure decreases to 9 MPa.The formation temperature is lower,and water vapor carries the heat of burned region to the combustion front,so the burning front is close to the producing wells.The cumulative oil production is 30.86 kt,and the recovery efficiency reaches 14.59%.
