Based on the inductive analysis of a large quantity of data collected in checking ammonium hydrolyzed polyacrylonitrile for drilling fluid in recent years, it is found out that the decreasing rate of filter loss of the saltwater base mud added to the test sample can not reach the standards of Q/CNPC 89-2003 ammonium hydrolyzed polyacrylonitrile for drilling fluid.
通过近几年对钻井液用水解聚丙烯腈-铵盐检验获得的大量数据进行归纳分析,发现在执行Q/CNPC 89-2003《钻井液用水解聚丙烯腈盐》标准的过程中,主要指标盐水基浆加样后滤失量降低率合格率很低。
The effect of nitrate or sulfate as counterions on flocculation properties of polydiallyldimethylammonium salts (PDADMAX) was investigated by using an optical monitoring technique together with the conventional jar test procedure and zeta potential measurement.
在实验室烧杯实验中,通过利用光散射监控技术,以及测定絮凝后上清液的残余浊度和Zeta电位,研究了硫酸根和硝酸根聚二甲基二烯丙基铵盐聚电解质(PDADMAX)的絮凝性能。
