井采技术在青海盐湖开发中的应用

Application of exploitation technology by well in development of Salt Lake in Qinghai

随着青海盐湖钾肥产量的不断提升,目前以渠采为主的采卤方式已不能满足生产需要,为保持钾肥生产的连续性,矿区服务后期将逐渐过渡成以井采为主的采卤方式。本文从采卤井的工艺设计、采卤设备、淡水系统、输卤系统等方面简要介绍了井采技术在青海盐湖开发中的应用。

With ever increase of the output of potash fertilizer in Salt Lake, Qinghai, at present, the method of mining halogen based on canal mining can not meet the needs of production. To maintain continuity of the potash fertilizer production,mine serv- ice will gradually transit to well extraction at the later stage of mine service. This paper briefly introduces the application of well mining technology in the development of Salt Lake in Qinghai in terms of process design of brine well, extraction equipment, fresh water system and brine transportation system among others.
