采卤深井预防结晶堵塞的措施

Preventive measures of crystallization blockage in deep well mining

本文介绍了深埋盐矿的地温梯度和岩盐溶解度特点,初步分析了出卤井内盐类结晶的一般规律,提出了利用超过晶粒临界流速的方法,防止盐类晶体在管道内的附着和沉积,并以此提出了生产套管口径和配水中心管长度和口径等参数的设计原则。

This paper introduced the geothermal gradient and salt rock solubility characteristics of deep salt mine,a preliminary analysis was given to the general law of salt crystallization in the brine well, and put forward the method of preventing the salt crystals from sticking and depositing in the pipeline by using more than critical velocity of grain. Based on the above, the design principles of the parameters are also proposed to the diameter of the production casing and the length and diameter of the water distribution central pipe.
