| 摘 要： | 广6注入水系统注入水结垢的主要原因是地层产出水中含有大量的成垢离子,加上水中含泥砂太多,在生产过程中,地层水从地层到地面温度和压力都下降,使地层水的溶解平衡被破坏,原来饱和的地层水为达到新的平衡而结晶,析出后与地层中的泥沙一起沉积在管壁上。针对这种情况,采取控制PH值、去除溶解气、进行水的软化处理等方法进行防垢,效果较好。在广6注水系统投加缓蚀阻垢剂DF-3(浓度为30mg/l),其缓蚀率为91.2%,阻垢率为97.8%。

| Abstract: | This paper analyzes the main reasons why injected water scales in Guang-6 Water Injection System of Bamianhe Oilfield and proposes several efficient methods including controlling pH value,removing dissolved gas and softening water.Adding DF-3(30mg/l concentration) corrosion and scale inhibitor into Guang-6 water injection system gets 91.2% rate of corrosion inhibition and 97.8% rate of scale inhibition. |
