摘　　要：盐酸和土酸都是油田矿场常用的酸化增产剂,两者外观相似,现场作业时有混用的安全风险。目前基于国标对盐酸和氢氟酸的检测方法,大多需要精密仪器,时效性不高。针对该问题,基于盐酸滴定法和氟试剂-比色法的技术思想,提出一种利用氟离子和茜素氨羧络合剂的反应作为核心检测手段的检测试棒,该试棒能直接进行现场检测,无需复杂仪器,还能够对检测样品进行中和及无害化处理,避免污染环境。最后的应用例显示该试棒具有较好的应用效果,有较大推广价值。Hydrochloric acid and mud acid are common acidizing stimulation agents in oil field.They are similar in appearance,so there is a risk of mixed use in field operation.At present,the detection methods of hydrochloric acid and mud acid based on the national standard,most of them need precision instruments and the timeliness is low.In order to solve this problem,based on the technical ideas of hydrochloric acid titration and fluorine-colorimetric method,a test bar was designed which uses the fluorine-colorimetric as the core detection method.The test bar can not only be directly used for field detection without complex instruments,but also neutralizes and innocuous samples to avoid environmental pollution.Finally,the application shows that the test bar has a good application effect and a great promotion value.
