摘　　要：深层油气、海洋可燃冰等苛刻环境资源逐渐成为能源主要采收领域。愈发苛刻的钻采环境对石油钻杆服役性能提出了更高的需求。高性能钛合金钻杆具有低密高强、耐蚀及抗疲劳等特性,可有效提升高温、高压、高腐蚀及动载荷等苛刻环境下的能源钻采能力和效率。分析了我国钛合金钻杆大规模推广应用的制约因素,综述了强酸及复杂动载钻采环境下钛合金钻杆的腐蚀、疲劳等服役损伤行为机理研究进展,结合实际服役工况,指出了存在的问题,展望了将来的研究方向。Harsh environmental resources such as deep oil and gas and marine combustible ice have gradually become the main fields of energy extraction.The increasingly harsh drilling environment has put forward higher requirements for the service performance of oil drill pipe.High performance titanium alloy drill pipe features low density,high strength,corrosion resistance and fatigue resistance to effectively improve energy drilling capacity and efficiency in harsh environments such as high temperature,high pressure,high corrosion and dynamic load.In this paper,the factors restricting the large-scale promotion and application of titanium alloy drill pipe are analyzed,meanwhile the research progress of service damage behavior such as corrosion and fatigue of titanium alloy drill pipe under strong acid and complex dynamic load drilling and production environment is reviewed.Combined with the actual service conditions,the existing problems are pointed out and the future research direction is prospected.
