钛合金油井管研究开发

Research and Development of Titanium Alloy OCTG

被称为海洋金属的钛合金,具有独特的耐海水腐蚀、冲蚀性能.论文通过全面探讨钛合金管用作油井管 的材料优势,针对钛合金管材独特的力学、机械性能,在特殊螺纹设计开发、酸化缓蚀剂研究开发等方面开 展系统研究,解决了一系列技术难题,成功开发出钬合金油井管,为我国高腐蚀环境下管材选用和深层油气 开发提供了一种具有战略意义的新型材料.

Titanium alloys,known as marine metals,have unique properties in both corrosion resistance and erosion resistance. The material advantage of the OCTG （Oil County of Tubular Goods） through a comprehensive study of titanium alloy tube for development of special thread design,and acidification,a series of technical problems has been solved. Successful development of titanium alloy OCTG provides a new type of material, which has strategic significance for the selection of materials in severe corrosion environment in deep oil and gas development.
