PAM泥浆问世已有十几年,首先在石油钻井中使用,取得了良好效果。PAM泥浆流变性能好,固相含量低,对钻速的提高和对造浆地层的稳定,以及控制地层造浆都起到了显著作用。几年来,PAM泥浆在煤田钻探中使用效果也很明显,去年,我们第一次在河东煤田使用PAM泥浆,无论是钻速的提高,还是泥浆成本都远远好于普通细分散泥浆。但是,由于时间短,工作量有限,有些对比试验和室内定量分析还没来得及完成,因此只能对所做的工作做点粗浅定性的分析。
PAM mud came out more than a decade, first used in oil drilling and achieved good results. PAM mud has good rheological properties, low solid content, improved penetration rate, stable stratum formation, and controlled formation formation. PAM mud has also been used for drilling in coalfields for years. In the past year, for the first time, we used PAM slurry at Hedong Coalfield. The increase in drilling rate and mud cost are much better than ordinary finely divided slurries. However, due to the short time, the limited workload, and some comparative experiments and indoor quantitative analysis have not yet been completed, so only the work done to do some qualitative and qualitative analysis.
