根据电磁场理论、能量守恒原理和两相流原理，给出了单井电阻加热油藏的数学模型。利用数学模拟方法研究了油藏电导率和油层厚度对电热效率的影响以及电阻加热油藏中的温度分布问题，讨论了输入电功率对原油采收率的影响。数值计算结果表明，输入电功率越高，原油采收率增加的幅度越大，随着无因次油藏电导率的减小，电热效率提高，有效加热半径也增大。在电阻加热油藏工艺中应防止电极处出现温度过高的现象
According to electromagnetic field theory, energy conservation principle and two-phase flow theory, a mathematical model of single well resistance heating reservoir is given. The effects of reservoir conductivity and reservoir thickness on electric heating efficiency and temperature distribution in resistance heating reservoirs were studied by using mathematical simulation method. The effect of input electric power on oil recovery was discussed. The numerical results show that the higher the input electric power, the greater the magnitude of the increase of crude oil recovery. With the decrease of the conductivity of the non-dimensional reservoir, the electric heating efficiency increases and the effective heating radius also increases. In the resistance heating reservoir process should prevent the electrode at the phenomenon of over-temperature
