中文摘要:
      目的 对镍钨合金镀层在连续油管上的应用进行初步探索。 方法 通过直流电沉积法,在 QT-900 连续油管表面沉积镍钨合金层。 模拟某油田腐蚀环境,通过高温高压腐蚀实验,采用金相显微镜、SEM 和 EDS 等分析手段,对比镀镍钨合金连续油管和普通连续油管的耐蚀性能,研究在 CO2 介质中镍钨合金镀层对油管耐蚀性的影响。 结果 镍钨合金镀层中主要含 Ni 和 W 元素,Fe 和 Mn 元素含量较少,镀层平均厚度在 55 μm 左右。 在温度 60 ℃ ,CO2 分压 1. 07 MPa,拉应力 439 MPa 的条件下,镍钨合金镀层的平均腐蚀速率为 0. 0160 mm/ a,约为普通连续油管的 1 /40,属于轻度腐蚀。 结论 镍钨合金镀层具有良好的耐 CO2 腐蚀性能。
英文摘要:
      Objective To preliminarily explore the application of Ni-W alloy coating in QT-900 coiled tubing. Methods Ni-W alloy coating was deposited on the surface of QT-900 coiled tubing by DC electrodeposition. An oilfield corrosion environment was simulated by high temperature and high pressure corrosion tests. The effect of Ni-W alloy coating on coiled tubing was studied by comparing the corrosion resistance of Ni-W alloy coating and coiled tubing using analysis methods such as microscopy, SEM and EDS. The effect of Ni-W alloy coating on the corrosion resistance of oil tubing in CO2 medium was studied. Results Ni-W alloy coating mainly consisted of Ni and W elements, and the Fe and Mn contents were low. The average thickness of the coating was 55 μm. The uniform corrosion rate of Ni-W alloy coating was 0. 0160 mm/ a at 60℃, with a CO2 partial pressure of 1. 07 MPa and a tensile stress of 439 MPa, which was 1 /40 of that of the ordinary coiled tubing. The corrosion rate belonged to slight corrosion. Conclusion Ni-W alloy coating had a good resistance to CO2 corrosion.
