| 摘 要： | 将溶蚀反应的溶蚀速率常数和多级反应级数引入到碱溶液传输方程中,建立了碱溶液在地层矿物多孔介质中含多级反应动力学的传输方程,并计算了碱溶液在地层矿物中一维浓度的分布.结果表明,物理模拟和数值模拟的一致性较好.该计算方法可以用作碱溶液传输过程的机理分析和实际驱替过程的模拟.分析了影响碱溶液在地层多孔介质中浓度分布的因素,如吸附、扩散系数、注入量、驱替速度和溶蚀等.该模型可用于预测碱耗、优化碱溶液浓度和注入量等参数,改善碱水驱或含碱复合驱的驱油效果,提高地层原油采收率.图5表1参16

| Abstract: | The alkaline solution transmission equation in the porous media of stratum mineral was built which applied dissolution speed constant and multi order reaction co-efficiency to the one-dimensional fluid equation and two-dimensional fluid equation.The concentration distribution of alkaline solution was calculated.The results showed that numerical value and physical value were similar and their regularity fit well.This calculating method could be used for analyzing the alkaline transmission mechanism and simul... |
