【摘要】 室内合成出四种缓蚀组分,并以其为主剂复配出一种主要针对油井酸化使用的缓蚀剂LX-1,通过静态动态失重法在不同温度、不同加量以及不同酸液类型及酸液浓度下,对其缓蚀性能进行了综合评价,并对其缓蚀机理进行了探讨。腐蚀试验表明,在140℃以内,20%的盐酸和15%的土酸中只需加入0.3%~3%的LX-1缓蚀剂,即可满足石油天然气行业标准中酸化缓蚀剂一级品的要求。更多还原

【Abstract】 Four kinds of inhibitor were synthesized in laboratory,and corrosion inhibitor LX-1 for acidifying oil well was prepared by combining such corrosion inhibitors.The performences of LX-1 were evaluated by weight-loss test at various temperatures,inhibitor concentrations and difierenttypes and concentrations of acids.The results showed that the performance of anti-corrosion could meet the oil and natural gas industry standards by just adding 0.3%~3.0%LX-1 to 20%hydrochlotic acid below 140℃.更多还原
