摘　　要：针对水井酸处理中用酸量和最佳用酸浓度问题 ,通过理论分析和数学推导 ,提出了一套水井酸处理用酸量的确定方法 ,即通过被处理碳酸盐岩含水层张开裂隙数目来计算用酸量 ;研究表明 ,用酸浓度越低 ,水井酸处理的效果越差 ;对华中科技大学供水井分别注 2 .4mol/ L盐酸 4t,4.8m ol/ L的 4t,9.5 mol/ L的 3.7t,进行了 3次酸处理 ,井的涌水量分别增加 0 % ,2 0 % ,10 0 % 。The technological problems in well acidation are the calculation of quantity of acid and argument on acid concentration in the well acidation.A method to serve this purpose is given by mathematical deduction,which can calculate directly quantity by the number of open fissures in the carbonatite aquifer.The research indicates the thinner the acid is used,the worse the well acidation result.Almost same amount of chlorhydric acid(3.7-4.0 t) was injected for a well in Huazhong University of Science and Technology,but the concentrations were 2.4 mol/L,4.8 mol/L and 9.5 mol/L respectively.The incremental rates of well discharge were 0%,20%,100% correspondingly.This demonstrated that strong acid should be used in well acidation.
