摘要：  针对原位电法加热油页岩层的问题, 运用F LUENT模拟仿真软件建立油页岩层的物理模型, 并对油页岩的温度场分布进行了数值分析。分析结果表明, 加热效率随着时间逐渐升高, 当加热井与产油井交换加热时,加热效率显著提高。当加热时间小于3a时, 油页岩层温度均匀地增加, 但是没有达到油页岩集中热裂解所需的温
度; 加热时间大于3a时, 油页岩层温度升高到3 5 0~5 0 0℃, 达到了油页岩集中热裂解所需的温度。油页岩热裂解后其导热系数、 孔隙度和渗透性都会随着油页岩温度的升高而增加。由此可见, 对油页岩温度场进行分析与控制,有助于提高油页岩的加热效率和产量。

Abstract: According to the technology of situ electrical heating on oil shale, a physical model was established by FLUENT. Numerical analysis of temperature field distribution of oil shale was carried out. In this model, the healing efficiency was increased by time, which was obviously increased when the heating well and oil well exchange heating. When the heating time was less than 3 a, the temperature of oil shale layer was increased steadily. But it did not reach the temperature that oil shale pyrolysis required. When the heating time was greater than 3 a, the temperature of oil shale layer was reached to 350～500 ℃. And it reached the temperature that oil shale pyrolysis required. After pyrolysis, the thermal conductivity, porosity and permeability of oil shale were increased while the temperature was elevated. Therefore, the analysis and control of temperature field of oil shale was helpful to improve the heating efficiency and production of oil shale.

Key words: Oil shale, Electric heating, Pyrolysis, Simulation, Isotherm
