摘　　要：介绍了铝合金钻杆的结构特点和材料特性,分析了其适用范围。认为:铝合金钻杆在塔里木油田含H2S井使用可有效防止钻杆发生应力腐蚀开裂和电化学腐蚀;在水平井和大斜度定向井使用可以减缓钻杆接头的热裂问题;在深井和超深井使用可减轻钻柱重量,增加钻井深度;在复杂井使用可增加套管下入深度。铝合金钻杆发生断裂事故之后容易将落鱼部分磨掉,这有利于提高处理井下复杂情况或事故的能力。同时指出了使用铝合金钻杆存在的问题和应注意的事项。This paper introduces feature and material characteristic of aluminum drill pipe and analyzes its application. It is believed that using aluminum drill pipe can prevent drill pipe from stress corrosion crack and electrochemistry corrosion in wells containing H2 S, protect tool joints from friction crack in hor- izontal and directional wells, can decrease drill stem weight and increase drilling depth in deep and extra deep wells, and can add casing running down depth in complex wells in Tarim Oilfield. Using aluminum drill pipe can improve capability of treating complex accident because aluminum drill pipe can be easily worn if fracture happens. It is also pointed out that there are some problems during using aluminum drill pipe.
