According to the working environment of the polar glacier core drilling, a separatory funnel capillary viscometer which can be used for testing the viscosity of liquids under ultra-low temperature conditions was de- signed. This viscometer has a simple structure and it is easy to operate, which can meet the testing requirements of different temperature conditions. The viscosity of the dimethyl silicone oil KF-96L-2.0cs was measured under different temperatures using this designed viseometer, and it is found that the viscometer coefficient K changes linearly with temperature. This testing method has relatively high test accuracy and its relative error is less than 4%, which can be used to test the viscosity of the different liquids in ultra-low temperature conditions. 展开更多

文章通过对井孔残留泥浆的影响和洗井质量对含水层渗透系数的讨论,可以看出采用传统的方法洗井或不彻底清除钻孔泥浆时抽水试验求得的含水层渗透系数k值以影响系数α值加以修正,其结果与实验室理想条件下的渗透系数k值比较接近。
关键词 渗透系数 钻探条件 泥浆钻进 洗井质量 液态二氧化碳井喷洗井法
