摘　　要：标准螺纹不能满足高温压、高腐蚀、高抗扭等严酷工况的油气井管柱要求,国内在非标螺纹研发方面尚存在较多不足。文章通过调研我国特殊螺纹油套管的主要类型,研究特殊螺纹油套管性能及技术特点,从特殊螺纹接头性能、密封效果、扭矩台肩等关键参数设计方面,分析特殊螺纹性能特点及技术共性,总结海上油田特殊螺纹油套管适用性,旨在为我国海上油套管的发展提供指导。The standard thread cannot meet the requirements of oil and gas well pipe and column under harsh working conditions such as high temperature pressure,high corrosion,and high torsion resistance,and there are still many deficiencies in the research and development of non-standard threads in China.Through the investigation of the main types of special thread oil casings in China,the article studies the performance and technical characteristics of special thread oil sleeves,analyzes the performance characteristics and technical commonalities of special threads from the design of key parameters such as special thread joint performance,sealing effect,torque shoulder,etc.,summarizes the applicability of special thread oil casings in offshore oilfields,and aims to provide guidance for the development of offshore oil casings in China.
