  And then,the mass percentages of HCl,HF,acidizing corrosion inhibitor and sludge inhibitor are optimized at 8%,4%,0.8%and 1%respectively. In order to prevent secondary precipitation,HAC solution of 1%—2%is mixed with acidizing compounded additives at 3%instead of conventional anti-clay swelling agent and active agent.

  在此基础上,对盐酸、氢氟酸、酸化缓蚀剂和防淤渣剂的质量分数进行了优化,确定其质量分数分别为8%,4%,0.8%和1%,为防止二次沉淀产生,应添加质量分数为1%～2%的醋酸溶液,并加入了质量分数为3%的酸化复合添加剂,以替代常用的防膨剂和活性剂。
