油田注水缓蚀剂的合成及性能评价

Synthesis of Corrosion Inhibitor for Oil Field Injection Water and Performance Evaluation

通过浸泡用腐蚀失重法测试了所制备的苄基乙二胺在盐水中对碳钢的缓蚀效果。试验结果表明,该缓蚀剂在50℃以下的盐水溶液中对碳钢具有较好的缓蚀效果。与一定比例的亚硫酸钠和磷酸二氢锌复配时可达到很好的缓蚀效果。

The static weight - loss method was used to test the corrosion inhibition performance of the benzyl ethylenediamine for carbon steel in aqueous salt solutions. The testing results indicated that, in aqueous salt solution below 50℃, the corrosion inhibitor had good corrosion inhibition effect for carbon steel. With a certain proportion of sodium sulfite and zinc dihydrogen phosphate, a very good eorrosion inhibition performanee can be achieved.
