国内外主要油(气)田水中锂提取现状及展望

油(气)田中常伴生油(气)田水，与自然界其他水体相比常具有较高的锂含量，部分可达工业品位。我国油(气)田水储量大，锂资源量可观，但在过去却长期被忽视。近年来，在盐湖卤水型液体锂资源提取技术不断取得突破的大背景下，卤水型锂资源产量占比逐年升高，油(气)田水型锂资源也应当受到重视。本文通过研究大量国内外主要油(气)田中伴生的油(气)田水锂含量及分布特征，归纳国内外油(气)田水提锂技术现状，为我国油(气)田水中锂的综合利用提供参考。

Current status and prospects of lithium extraction in major domestic and foreign oil (gas) field waters

Oil (gas) fields are often accompanied by oil (gas) field water, which usually hashigh lithium concentration than some other waters in natural environment, and some of them even can reach lithium industrial grades. Chinese oil (gas) field has large water reserves and lithium resources. However, it has been neglected for a long time. Under the background of a series of breakthroughs were made in extracting lithium from salt lake brine, the proportion of brine type lithium resources has increased year by year. Lithium resources in oil(gas) field water should also be taken into account seriously. Lithium concentration and distribution characteristics of oil (gas) fields water and summarizes the current status of water extraction technology in the main domestic and foreign oil (gas) fields were summarized in this study to providing advices for the comprehensive utilization of oil (gas) fields water in China.
