摘要
以克拉玛依油田H1井区火驱试验为例,从物质和能量守恒出发,推导了高温燃烧条件下地下燃烧参数的平衡关系式,分析了火驱过程中原油、岩石骨架、次生水体等的热量分配,对H1井区地下燃烧温度、空气消耗量、空气油比等参数进行了计算,结果表明,在实际生产过程中油层空气消耗量为350~400 m^3/m^3,地下燃烧温度约为550℃,对实验室数据进行了重新标定。在此基础上,为了进一步提高火驱开发效果,对湿烧注入方案进行计算,当空气消耗量为350 m3/m3时,湿烧水空气比为0.000779 m^3/m^3,日注冷水量为49.9 m^3。
Taking the combustion test in Wellblock H1 as a case,and starting from the conservation of matter and energy,the equilibrium relationship of underground combustion parameters under high-temperature combustion conditions is deduced,then the heat distribution to crude oil,rock skeleton,secondary water and other matters is analyzed in the process of combustion,and finally the parameters such as combustion temperature,air consumption,and air-to-oil ratio are calculated.The results show that in the actual production process,the air consumption of the oil layers is about 350 to 400 m^3/m^3,and the underground combustion temperature is about 550℃.Based on the results,the experimental data are updated,and in order to further improve the development effect of fireflooding,the wet combustion plan is calculated.When air consumption is 350 m^3/m^3,the wet combustion water-to-air ratio is 0.000 779 m^3/m^3,and the cold water injection is 49.9 m^3/d.
