SF-103油田注水缓蚀剂的合成及性能考察

SYNTHESIS AND PROPERTIES OF CORROSION INHIBITOR SF 103/

以石油酸和有机胺为原料合成ＳＦ１０３油田注水缓蚀剂。对胜利油田多个采油厂回注水的试验表明，ＳＦ１０３油田注水缓蚀剂适用于中性及偏酸性污水的缓蚀。当缓蚀剂的加入量在１０～２０ｍｇ／Ｌ时，其缓蚀效果可达９０％左右，平均静态腐蚀速率小于０．０７６ｍｍ／ａ．ＳＦ１０３缓蚀剂的原料来源广，生产成本低，生产过程简单且无三废污染，是一种较有应用前景的油田注水缓蚀剂。

The corrosion inhibitor SF 103 was synthesized with petroleum acids, polyamine and other materials. It shows good corrosion protection property to neutral or sour sewage in oilfields. When the concentration of corrosion inhibitor is 10～20 mg/L, the corrosion protection rate is about 90%, and the corrosion rate is less than 0.076 mm/a. Due to the low priced raw materials and good corrosion protection property of the product, SF 103 corrosion inhibitor revealed a good application forecast.
