井矿盐三井链接技术的研究与应用

摘要

三井链接技术就是在岩盐矿开采中,实施两口水平井与一口直井对接连通,形成一个链接连通采卤井组。一个链接井组相当于两个对井井组,实际产卤能力可达160m3/h,卤水浓度范围为303～308g/L;三井链接技术先进、可靠,且一个链接井组少一口直井,大幅节约了矿山建井投资。%Three-well link technology is to realize docking connectivity among 2 horizontal wells and 1 vertical well during the rock salt mining to form a link well group for brine extraction.One link well group equals to two docked well groups and the actual capacity of brine extraction can reach 160m3/h,and the concentration of the brine is around 303～308g/L.The 3-well link technology is advanced and reliable,and every link group has 1 vertical well less that a lot of the investment of well construction in mine can be saved.
