摘　　要：对ＮａＯＨ溶解开采深埋型天然碱时井内易结晶、碱液浓度低的原因进行了分析。认为助溶剂ＮａＯＨ浓度低是碱液总碱度低的主要原因；井内温降大是碱卤水在井内提升运输过程中易堵管、障壁的主要原因。并提出了解决办法。The reason of easy-crystallized and low alkali content in the well by means of NaOH dissolving exploitage for embeded natural alkali has been analyzed. The low dissolving agent content was considered main factor which caused low total alkality in the aqueous alkali. The temperature plummeting in the well was the main reason for the pipeline clogging and scaling during alkali halide hoisting transportation. The related measures were also put forward.
