井采技术在罗布泊盐湖开发中的应用

Application of exploitation technology by well in development of Lop Nor Salt Lake

罗布泊盐湖罗北凹地钾盐卤水矿床埋深超过100 m,必须采用井采方式回采,由于工艺、设备等原因,多年来国内盐湖井采的大规模工业化受到限制。本文结合新疆罗布泊钾肥基地年产120万t钾肥项目,从盐湖矿床特点、采区布置、采卤井结构、输卤渠防渗和效果分析等方面,简要介绍了井采技术在罗布泊盐湖开发中的应用。

Commereial exploitation of domestic salt lake brine by well has been hmited for many years due to reasons of process, equipment etc. but potash brine deposit with burial depth of over 100 m in Luobei depression, Lop Nor Salt Lake have to be exploited by well. The paper deals with application of exploitation technology of brine by well in development of Lop Nor Salt Lake brine, introducing the deposit features, layout of exploiting well, structure of the well, antiseepage effect of trench for transporting brine etc. in combination with 1.2 Mt/a potash project in Xinjiang Lop Nor Potash Base.
