摘要

试验研究了尺度因子对D16T铝合金和G-105钢钻杆疲劳特性和失效机理的影响。确定了两种材料的试样多循环试验极限和钻杆原位全尺寸试验疲劳寿命。在全尺寸试验中，材料的疲劳特性显著降低。结果表明，铝合金钻杆满足API RP 7G对G-105强度组钢钻杆的要求，在具体性能上比钢管有明显优势。

Effect of Scale Factor on Cyclic Strength of Drill Pipes from Aluminum Alloy D16T and Steel of Strength Group G-105

The effect of the scale factor on fatigue characteristics and failure mechanisms of drill pipes from aluminum alloy D16T and steel G-105 is studied experimentally. The endurance limit in multicycle tests of samples and the fatigue life of drill pipes in in-situ full-scale tests are determined for both materials. A significant decrease in the fatigue characteristics of the materials is detected in the full-scale tests. It is shown that the drill pipes from aluminum alloys meet the requirements on pipes from steel of strength group G-105 according to API RP 7G and have a significant advantage in the specific characteristics compared to steel pipes.
