摘　　要：通过常温、中温海泥中的恒电流电化学性能 ,短期及长时间试验 ,阳极自耦合放电 ,阳极表面溶解的宏观及微观分析 ,以及阳极极化曲线测试 ,为某油田找到了一种性能优良适合海底管线阴极保护用的Al牺牲阳极 (WPT2阳极 )Several Al anodes were evaluated by a serious tests:i.e.current static tests in sea bed mud under normal and moderate temperature for long-term and short-term, anode close circuit discharge tests, microanalysis of anode surface dissolution morphology and measurement of anodic polarization curve.A high quality Al anode (WPT 2) was finally recommended to fit the reqnirements for the protection of oil-carrying pipelines in sea bed mud.
