一种防腐合金组合物及其装置、制备和应用
摘要：
本发明提供了一种防腐合金组合物及其装置、制备和应用。本发明所述组合物包括如下重量百分比成分：硅0.4-0.8％、铁0.7％、铜0.15-0.4％、锰0.15％、镁0.8-1.2％、铟0.04-0.35％、锌3.2％、钛0.15％、其余为铝。本发明的组合物制备的防腐装置具有优异的主动防腐性能，牺牲自己而保护隔热油管，减少隔热油管等井下工具因腐蚀而产生的井内液体泄漏的可能性。
摘要（英）：

The invention provides a corrosion-resistant alloy composition as well as a device, a preparation and an application thereof. The corrosion-resistant alloy composition comprises the following components in percentage by weight: 0.4-0.8% of silicon, 0.7% of iron, 0.15-0.4% of copper, 0.15% of manganese, 0.8-1.2% of magnesium, 0.04-0.35% of indium, 3.2% of zinc, 0.15% of titanium and the balance of aluminum. A corrosion-resistant device prepared from the alloy composition has excellent active corrosion resistance and the alloy composition is sacrificed to protect thermal-insulation oil pipe and thus the possibility that the liquid inside a well is leaked due to the corrosion of downhole tools such as the thermal-insulation oil pipes is reduced.
