摘　　要：对现有闲置的12"输油海管线进行了分析校核,并通过工艺改造将其用于天然气的输送。工艺、强度、防腐、结构等方面的校核结果表明,该海管在最大操作压力不超过1.0 MPa,最大操作温度不超过40℃时,符合规范要求,具备安全使用条件。经适当的工艺改造后该12"海管最大输气量为28.6万方/天,完全满足天然气的输送要求,实现该海上平台伴生气全部回收利用,达到零排放的目标,对海洋油气田的开发生产、改造具有良好的参考价值。The idle 12＂ oil pipeline was checked, and transformation process was studied to transform it to natural gas. Conditions, strength, corrosion and structure of the oil pipeline were studied. The result showed that it can be safety working under the pressure 1.0 MPa and under the temperature 40℃. After appropriate process modification, the oil pipeline can transport 286 thousand cubic meters as maximum peer day, and fully met the requirements for transport of natural gas to completely recycle associated gas of the offshore platforms, the goal of zero emissions can be achieved. It will be a good reference for the development and transformation of offshore oilfield.
