要:通过中原油田生产系统产出液的腐蚀性调查,以油酸、二乙烯三胺和二甲苯为原料,通过合成、复配与评价试验,室内合成了适用于中原油田油井产出液的缓蚀剂KY-2.应用静态、动态挂片,电化学极化曲线评价其缓蚀性能及缓蚀机理.自2009年中原油田六个采油厂的现场应用表明,KY-2缓蚀剂的加入量在100mg/L时,腐蚀速率明显降低,其缓蚀效果可达90%左右,平均静态腐蚀速率小于0.076mm/a,并且总铁降低,趟井次数降低,经济效果显著,防腐效果良好,具有较好的推广应用前景.

@@@@It is about water’s corrosion from Zhongyuan production system. According to the situation that anti-corrosive is good at oil-soluble but bad at inhibition of corrosion. We composed five kinds of water-soluble and oil-microsoluble anti-corrosive agent in lab. In this paper, The corrosion inhibitor KY-2 ware synthesied with oleic acids, diethylenetriamine and other materials and It shows good corrosion protection property to sour sewage in oil fields. The chemical structural formula of corrosion inhibitor KY-2 ware studied by infrared spectrogram. The corrosion inhibition performance were investigated by weight-loss measurement and electrochemical polarization curves. When the cocentration of corrosion inhibitor is 100 mg/L, the corrosion protection rate is about 90%, and the corrosion rate is less than 0.076 mm/a, the iron ion in the production water and times for corrosive well repair was reduced. After KY-2 used a significant economic effect and anti-corrosion effect is good, and application prospect is good.
