JM403油田注水缓蚀剂的合成及性能评价

Synthesis and Properties of Corrosion lnhibitor JM403 for Water Flooding

以脂肪酸、多胺和丙烯酸甲酯为原料合成JM403油田注水缓蚀剂。用静态挂片法测定了在青海油田注入水中对A3钢的缓蚀性能。试验结果表明,当JM403加量为30mg·l-1时,60℃下其缓蚀率为735%,平均静态腐蚀速率小于0076mm·a-1。此外。

The corrosion inhibitor JM403 was synthesized with fatty acid,polyamine and methyl acrylic ester.The inhibitory performance for carbon steel A3 in injection water was determined by the static corrosion experiments.When the concentration of corrosion inhibitor is 30 mg·l -1 the corrosion protection rate is about 73 5% at 60℃,and the corrosion rate is less then 0 076 mm·a -1 .The corrosion inhibitor JM403 was compatible with scale inhibitor PBTC and biocide 1227.
