摘　　要：对泥浆加重材料重晶石粒度分析一直沿用GB5005中的湿筛分析法,只测76um和43um颗粒的筛余量.而API方法还要求对小于6um颗粒进行测定.本文参考API方法,并在此基础上提出采用增粘延时之手段,用密度计法测定重晶石的粒度分布.经试验验证,该法是一种重晶石粒度分析的有效方法.:Wet screening in the GB5005 has been using in the grading analysis of baryte,andmeasures only the particle of 76um or 43um. But the API standard also requires measuringless than the screen tailings of 6um. Based on the above and referring to the API standard,the article suggests a new way of measuring the distribution of the baryte grading by increas-ing viscesity and time with a densitometre.
