从威远气田水中提取碳酸锂、溴化钠、氯化钾已分别由四川自贡市井盐设计研究所张家坝制盐化工厂和地质矿产部综合利用研究所完成扩大试验和中间试验任务。十月中旬,四川省科委在自贡市召开了技术鉴定会并通过了鉴定,为气田水的综合利用展示了美好前景。威远气田水是开采天然气过程中采出的卤水,其中含有锂、溴、钾、铷、铯等多种有用元素,这些如不加以利用,不仅严重阻碍天然 Lithium carbonate, sodium bromide and potassium chloride were extracted from the water of Weiyuan Gas Field. The expansion and intermediate tests were completed respectively by the Zhangjiaba Salt and Salt Chemical Plant and the Institute of Geology and Mineral Resources of Zigong City Salt Design Institute. In mid-October, the Sichuan Provincial Science and Technology Commission held a technical appraisal meeting in Zigong City and passed the appraisal, demonstrating a bright future for the comprehensive utilization of water in gas fields. Weiyuan gas field water is extracted during the exploitation of natural gas brine, which contains lithium, bromine, potassium, rubidium, cesium and other useful elements, which if not used, not only seriously hinder the natural
