本文阐述了环境温度对钻井泥浆脱水效应的实验研究。考察了三个温度范围,即自流线温度到室温、自室温到凝固点和自凝固点(-20℃)到融化点(+12℃)试验所用的泥浆包括未加重的和加重的淡水泥浆以及一种加重的盐水泥浆。 20℃以上的实验结果表明,从运行系统输出的钻井泥浆在60℃以上分离出的水只增加10%,就提高脱水率而言,只略有效果。低于20℃的温度实验表明,从运行系统输出的废钻井泥浆应该在高于5℃时即开始进行脱水。否则,为了增强分离效果就需要使用更多的化学剂,甚至脱水作用会变得完全无效。
This paper presents an experimental study of the effect of ambient temperature on drilling mud dewatering. The three temperature ranges examined, ie, the free-flowing and agitated freshwater slurries, were tested from room temperature to room temperature, from room temperature to the freezing point and from the freezing point (-20 ° C) to the melting point (+ 12 ° C) Increased brine slurry. Experimental results above 20 ° C show that the water separated from the drilling fluid output from the operating system above 60 ° C increases by only 10%, with only a slight effect in terms of increasing the rate of dehydration. Experiments at temperatures below 20 ° C have shown that the waste drilling mud output from the operating system should begin to dehydrate above 5 ° C. Otherwise, more chemicals are needed to enhance separation and even dehydration becomes completely ineffective.
