对钻井泥浆来说,粘土的造浆率高低是很重要的.我们希望造浆率越高越好.那么粘土造浆率高低是否可以作为评价粘土质量好坏的综合性指标呢?或者说,不论是什么类型的粘土(膨润土还是非膨润土,钠土还是钙土),只要是造浆率高就是好粘土?笔者和其他单位试验发现,有些粘土通过电镜、X光、差热分析等证实是膨润土,但造浆率并不高.用纯碱改型处理后,造浆率还是不高,表观粘度15厘泊时,造浆量小于6立方米/吨土.相反,有些以伊利石为主的粘
It is very important for the drilling mud to make the clay production rate, and we hope the higher the production rate, the better the clay production rate can be used as a comprehensive index to evaluate the quality of the clay. Or, No matter what type of clay (bentonite or non-bentonite, sodium or calcium), as long as the high rate of clay is a good clay? The author and other units found that some of the clay by electron microscopy, X-ray, differential thermal analysis confirmed that Bentonite, but the rate of making pulp is not high.With soda ash modification treatment, the rate of pulp production is still not high, the apparent viscosity of 15 centipoise, the amount of less than 6 cubic meters / tonne of mud.On the contrary, some with illite as The Lord’s sticky
