摘　　要：介绍了大庆油田酸化技术的发展史和技术现状,对大庆油田几年来酸化液腐蚀性检验中出现的问题及现象进行介绍和分析,对缓蚀剂用量不合理和点蚀的危害性进行阐述,同时介绍了目前常用单一型和复配型缓蚀剂、缓蚀剂适用酸化液类型及缓蚀剂适用井别,并对缓蚀剂用量、酸化液添加剂的选用、酸化液配制及监督等提出几点建议。对进一步提高大庆油田的酸化液产品质量,减少对地层造成的二次伤害,提高施工设备和管柱的使用寿命,减少施工事故,提高酸化液产品的性价比等,具有一定的指导意义。After an introduction to the developing history and technological status of acidifying technology in Daqing Oilfields, an analysis focuses on the problems and phenomenon existing in the corrosive inspection of acidifying fluid in Daqing oilfields in the past few years. While explaining the irrational usage of inhibitor and the hazard of pitting corrosion, the paper also introduces the current commonly-used single type and mixed type of inhibitors, the acidifying fluid types that inhibitor adapts to and the well kinds that inhibitor adapts to. Then several suggestions are put forward about the dosage of inhibitors, the selection of acidifying fluid addi- tives, the mixing of acidifying fluid and supervision. This study is of instructive significance in improving the quality of acidifying fluid products, reducing the second hazard caused by the stratum, increasing the service life of construction device and pipes,cutting down the construction accidents and raising the performance price ratio of acidifying products
