摘要
介绍了国内外铝合金钻杆的研制现状,分析了绳索取心铝合金钻杆在地质钻探中的优势。对?71 mm×5.5mm绳索取心铝合金钻杆体与钢接头连接结构进行了详细设计。通过对试验钻杆进行静拉力、扭矩试验,得出了铝合金钻杆体与钢接头主要技术参数。
The paper introduces the development situation of aluminum alloy drill pipe both in China and abroad and analyzes the advantages of aluminum alloy wire-line coring drill pipe in geological drilling. Ф71mm × 5. 5mm aluminum alloy coring drill pipe body and steel connection structure were designed in detail,the main technical parameters were obtained by the static tension and torque tests on the rods.
