摘要:

通过微观形貌观察、极化曲线测试、240 ℃-结盐-CO₂/O₂多因素耦合环境下的模拟实验，明确了热浸铝镀层在油田重沸器管束中的适用性。热浸铝试样主要由纯Al层和舌状Fe₂Al₅合金层组成，厚度在150~200 μm。模拟油田水中的极化曲线对比结果表明，在30 ℃时，热浸铝试样相比20#钢腐蚀电流密度降低约300倍，具有很好的耐蚀性能。采用高温高压反应釜模拟现场管束服役工况，高温高压模拟工况结果表明，240 ℃-结盐-CO₂/O₂多因素耦合环境下，20#钢的均匀腐蚀速率为0.68±0.04 mm/a，点蚀深度达到70.5 μm，表面的腐蚀产物主要为Fe₃O₄和Fe₂O₃，产物膜内存在大量裂纹等缺陷；而热浸铝镀层腐蚀速率为0.08±0.02 mm/a，腐蚀主要出现在纯Al层，对应的腐蚀产物为Al(OH)₃。综合结果表明，热浸铝镀层在240 ℃-结盐-CO₂/O₂多因素耦合环境下呈现良好的防腐性能。

Abstract：

The applicability of hot-dip aluminum (HDA) coating in oilfield reboiler tube bundles is studied by means of micro-morphological observation, polarization curve test, and 240 ℃-salt deposited-CO₂/O₂ multi-degree coupling environment simulation testing in this work. The HDA sample is mainly composed of pure Al outer layer and tongue-shaped Fe₂Al₅ inner alloy layer, and the thickness is between 150 and 200 μm. The polarization curves, which measured at 30 ℃ in simulated oilfield water, show that the corrosion current density of the HDA sample is about 300 times lower than that of 20#, and display excellent corrosion resistance. The simulated results at high-temperature-high-pressure environment show that the uniform corrosion rate of 20# steel in extreme environment is 0.68±0.04 mm/a, the maximum pitting depth is 70.5 μm in 240 ℃-salt deposited-CO₂/O₂ multi-degree coupling environment. In addition, the corrosion scales formed on the surface are consisted Fe₃O₄ and Fe₂O₃, and some cracks can be detected in the scales. However, the corrosion rate of the hot-dip aluminum coating is 0.08±0.02 mm/a, the corrosion mainly occurs in the pure Al layer, and the corresponding corrosion scale is Al(OH)₃ after simulated testing. The comprehensive results show that the hot-dip aluminum coating exhibits excellent anti-corrosion performance under this complex environment.

Key words： hot-dip aluminum coating 20# steel heat exchanger tube bundles electrochemical testing high-temperature-high-pressure simulation test
