摘　　要：【目的】防止油页岩注热开采过程中污染物污染临近的含水层,有助于开发区防渗帷幕的设计及优化。【方法】利用数值软件分析了油页岩注热生产期内污染物沿各方向的迁移规律。【结果】油页岩生产期内,污染物污染范围随注热时间逐渐扩大,污染物沿水平方向扩散更为明显;污染物水平方向上浓度峰值出现在距生产井6 m范围内,竖直方向上浓度峰值出现在油页岩矿层与顶底板交界处。【结论】污染物生产期间扩散运移规律为防渗帷幕的设计提供了参考。[Purposes] In order to prevent pollutants from contaminating adjacent aquifers during hot injection mining of oil shale,which is benefical to design and optimize anti-seepage curtain of the development zone.[Methods] Numerical software is used to analyze the migration rule of pollutants along all directions during the oil shale thermal injection production period and shutdown period.[Findings] During the oil shale production period,the pollutant pollution range gradually expands with the thermal injection time,and the pollutant diffusion along the horizontal direction is more obvious;The peak concentration of pollutants in the horizontal direction appears within 6 m from the production well,and the peak concentration in the vertical direction appears at the junction of the oil shale seam and the roof and floor.[Conclusions] The law of diffusion and migration of pollutants provides reference for the design of antiseepage curtain.
