酸化淤渣的生成是影响酸化效果的重要因素，而酸液浓度、酸液类型、酸化添加剂及酸液中的金属离子等对酸化淤渣的生成有影响。对渤南油田２个区块的油样进行了试验，重点研究了三价铁离子和二价铁离子对酸化淤渣生成的影响。结果表明，三价铁离子会促进淤渣的生成；二价铁离子对淤渣的生成也有一定的影响，但通以氮气对二价铁离子进行保护后，二价铁离子对淤渣生成的影响降低。针对义４－７－１０油样，筛选出ＣＨ－１和ＣＨ－２两种有效的防淤渣剂。这两种防淤渣剂复配使用（其浓度均为０．５％）时，预防淤渣效率可达９５％以上
The formation of acidified sludge is an important factor affecting the acidification effect, while acid concentration, acid type, acidification additives and metal ions in acid have an impact on the formation of acidified sludge. The oil samples of two blocks in Bonan Oilfield were tested. The effects of ferric iron and ferrous iron ions on acidified sludge formation were mainly studied. The results showed that the ferric ion promoted the formation of sludge. Ferrous ion also had some influence on the formation of sludge. However, ferrous ions could protect sludge from ferrous ions Impact reduced. According to the samples of Yi 4-7-10, two effective anti-sludge agents, CH-1 and CH-2, were screened out. The two kinds of anti-sludge agent used in combination (its concentration of 0.5%), the prevention of sludge efficiency up to 95% or more
