摘要
千米桥油田生产过程中井底油管存在的严重结垢和腐蚀问题 ,针对结垢和腐蚀类型 ,研制了一种抗高温的新型阻垢缓蚀剂PPS - 1。试验表明 ,该阻垢缓蚀剂在 180℃的温度下 ,即使加量较小 ,阻垢率仍可达 90 %以上、缓蚀率大于 75 %;且随着加量的提高 ,阻垢缓蚀率都逐渐提高 ,各性能明显优于目前常用的阻垢缓蚀剂 ;不仅适用于千米桥油田高温条件下的阻垢缓蚀 ,同样可解决中、低温条件下的阻垢缓蚀问题。
Both serious scaling and corrosion states come into existence in tube of well bottom during a process of production in Qianmiqiao Oilfield, in accordance with the categories of both scaling and corrosion, have manufactured a kind of new-type high temperature scaling retardace and corrosion inhibitor pps-1. Experiments indicate that under the temperature 180℃ even if additive volume is rather less the scaling retardace inhibiting ratio of this king of pps-1 is more than 75 per cent; both ratio of scaling ...
