为减少油页岩原位开采过程中的化石能源消耗,构建塔式太阳能聚热页岩油原位开采系统模型,对集热场蒸汽参数和油页岩开采井间距进行优化,并在此基础上展开余热回收研究以提高系统综合能效。结果表明：通过对蒸汽参数和井间距进行优化,系统热效率η可由22.4%升至33.5%,再对生产井出口的蒸汽余热进行回收利用后,系统热效率η进一步提升（升至38.4%）,页岩油生产成本Cp由306.0美元/t减少到174.7美元/t。
Abstract
Solar energy introduced in oil shale mining can reduce fossil energy consumption and carbon emissions. In this paper, an oil shale in-situ recovery system driven by solar tower is proposed, the steam parameters of the solar field and the spacing between producing wells are optimized. On this basis, the research on waste heat recovery is carried out to improve the energy efficiency of the system. The results show that by optimizing steam parameters and well spacing, the thermal efficiency η of the system can be increased from 22.4% to 33.5%, based on this, by recovering the steam waste heating of the production well, the thermal efficiency η of the system is further improved： increases to 38.4%, and the shale oil production cost PC decreases from 306.0 $/t to 174.7 $/t .
