Scaling will lead to a decrease in the volume of ocean pipe collection and corrosion problems.So it needs to be removed by means of the ball,but often the ball leads to the corrosion inhibitor film is constantly destroyed.In order to shorten the film process,it is necessary to develop a cleaning pre-film agent.In this paper,it was found that sultanic acid and citric acid had a good synergistic effect when the compound was 4:1,and the descaling rate could reach 100%when the dosage was 0.5%.Adding 15%quinoline quaternary ammonium salt to organic acid solution can effectively control the corrosion of acid wash solution and self-corrosion of formulation.The prefilm time of this agent is 300 minutes,the prefilm time is short,the prefilm effect is excellent,and meets the needs of the field.
