摘　　要：卤水锂矿是锂电池和电网储能材料的重要原料,也是国家战略性资源。锂产品市场供不应求的现状促使研究者们将锂提取的来源从常规的盐湖卤水扩展到地热卤水和油田卤水等非常规卤水。目前,全球常规卤水的提锂技术已经成功实现工业化应用,而非常规卤水的提锂技术仍然处于产业化开发阶段,尚有大量卤水锂资源未得到开发利用。基于非常规卤水中锂资源分布和组成等信息,剖析了非常规地热卤水和油田卤水直接提锂技术的研究现状,系统总结了沉淀、膜分离、溶剂萃取和吸附等主要提锂技术。此外,对目前国内外非常规卤水的提锂技术产业化现状进行了总结,并对未来非常规卤水提锂技术进行了展望,期望为地热卤水和油田卤水锂资源的绿色、高效开发提供借鉴与参考。The lithium brine is an important raw material for lithium battery and energy storage materials,and also the stra-tegic resources of the country.Demand for lithium has prompted researchers to expand lithium extraction from conventional salt lake brines to unconventional sources such as oilfield brines and geothermal brines.At present,the lithium extraction technology of conventional brines has been successfully applied in industrialization worldwide,while the lithium extraction technology of unconventional brines is still in the stage of industrialization development,and a large number of lithium re-sources in brines have not been developed and utilized.Based on the information of lithium resource distribution and compo-sition in unconventional brines,the research status of direct lithium extraction technology in unconventional oilfield brines and geothermal brines was analyzed,and the main lithium extraction technologies,such as precipitation,membrane separa-tion,solvent extraction and adsorption were systematically studied.In addition,the industrialization status of lithium extrac-tion technology of unconventional brines at home and abroad was summarized,and the future lithium extraction technology of unconventional brines was prospected,which was expected to provide reference for the green and efficient development of lithium resources of geothermal brines and oilfield brines.
