综述了高酸性腐蚀气田用BG2250镍基合金油井管国产化开发进展情况。通过与国外同类产品的实物质量分析以及成分、电弧炉冶炼、电渣重溶、锻造、热挤压、冷轧、特殊扣设计与加工、腐蚀评价等工艺技术的研究，宝钢开发的BG2250-125等镍基合金油管的产品质量达到了国际同类产品的先进水平，并已在普光气田成功下井使用，为我国高酸性气田的开发提供了重要的物资保障。

The development of Ni-based alloy BG2250 tubing used in severe sour gas field is introduced in this paper. With great efforts in analysing imported similar products, and researching the techniques,such as composition optimization, AOD melting, electro-slag remelting, forging, extrusion, cold rolling, premium thread connection designing and machining, and corrosion evaluation, etc.,the mechanical properties, corrosion resistance and pipe qualities of the Ni-based alloy tubing developed by Baosteel, such as BG2250-125, has reached advanced level compared with other international pipe companies. The Ni-based alloy tubing BG2250-125 has been successfully applied to Puguang gas well, which provides significant guarantee for the severe sour gas field exploration in China.
