Influence of W-based Amorphous Alloy Electroplating on Anticorrosion and Antiscale Performance of Well Tube Steel
摘 要
采用非晶态合金电镀技术在井下油管用P110试片表面制备了三层钨基合金,模拟高含CO2环境和高压富氧条件研究了合金的防腐蚀性能;通过现场中试研究了合金的阻垢性能,并与P110裸钢进行了比较.结果表明:镀钨合金试片对CO2、高压富氧等腐蚀环境具有较强的防腐蚀性,缓蚀率分别为96.88%和93.75%,现场中试阻垢率为41.73%,阻垢效果明显.钨基非晶态合金电镀技术是一种经济、适用的油田井下管杆防腐蚀、阻垢、防偏磨新技术.
Abstract
Three layer tungsten-based alloy was prepared on the surface of P110 well tube steel by amorphous alloy electroplating technology.The environments of high content of CO2 or high pressure with oxygen enrichment were simulated respectively to study the anticorrosion performance of the tungsten-based alloy.The antiscale performance of the tungsten-based alloy was studied by field pilot-scale testing.Compared to the P110 bare steel,the tungsten-based coating presented strong anticorrosion performance in the environments of CO2 or high pressure with oxygen enrichment.The corrosion inhibition efficienciy was 96.88% and 93.75% respectively.The anti-scale efficiency of the tungsten-based alloy could be 41.73%.W-based amorphous alloy electroplating technology is an economic and applicable technology for anticorrosion,antiscale and eccentric wear prevention of well pipes.
