精准定向技术在盐矿开采中的应用

摘要：北元拟新建的一个岩盐矿山，采用水平对接连通井组采卤工艺技术，为了探索优化采卤工艺路线和参数，利用探井实施了一个验证采卤井组。在该井组实施过程中，在常规定向技术的基础上，成功引进了“精准定向技术”。该井组一次性对接成功，并避免了仅采用常规定向技术所需的建槽工作及大量淡卤水的处理。该井组试运行采卤流量约75-100m3／h，卤水浓度290-310g／L，实施情况及采卤试运行结果证明了采用“精准定向技术”是先进、成熟、可靠的。

Application of Precision Orientation Technology in Salt Mine

A salt mine will be built in Beiyuan which will take the technology of brine extraction by horizontal docking connected well group. In order to explore and optimize the route and parameters of brine extraction technology, we carried out a verification brine well group by using exploratory well. In the process of the implementation of this well group, ＂precise orientation technology＂ is successfully introduced based on conventional orientation technology, the well group docking success only once which avoids groove construction work and the treatment of large amounts of dilute brine by using conventional orientation technology only. In the test run of the well group, the brine extraction flow is about 75-100 m3/h, and the concentration of brine is about 290-310 g/L. The implementation condition and test run of brine extraction show that the use of ＂precision orientation technology＂ is advanced, mature, reliable.
