摘要
四川气田各矿区地层水中均不同程度含有微量元素溴（Ｂｒ）、碘（Ｉ）、硼（Ｂ），其中Ｂｒ最为普遍，其分布与地层水矿化度关系密切，且大多具有工业利用价值；Ｉ含量次之，工业性分布以川中为主，川东、川西北次之；Ｂ含量较低，工业性分布较为局限，仅平落坝和磨溪分别有超过和接近工业单矿下限标准的Ｂ。作为伴生矿开采，综合利用Ｂｒ、Ｉ、Ｂ及ＮａＣｌ、Ｍｇ和混合盐类，可大大降低其工业下限含量标准，这也是四川气田开采后期走出经济效益困境的有效途径。
here are some trace elements of bromine(Br),iodine (I) and boron (B) in Sichuan gnsfield water.The bromine,with a distribution closely related to the salinity of the formation waters,is widespread and most of it are valuable for industrial utilization.The iodine takes the second content,with an industrial distribution over the gasfields dominantly in the center of Sichuan, secondly in the east and the northwest.The boron tubes a lower content,with a limited industrial distribution, only Pingluobs and Moxi gasfields are respectively above and near the industrial cutoff content.As the development of associated minerals,the comprehensive utilization of bromine,iodine,boron and the mixed salts of NaCl and Mg can reduce the cutoff values of industrial content. It is the effective measure of being extricated from a predicament of economic benefits for the gasfields in the later decline period of production.
