摘要
在滩海油田首次进行海底注水管道的铺设 ,受其结构等因素的影响 ,其施工工艺及技术性远比海底输油管道更复杂 ,难度更大。本文介绍了滩海油田海底注水管道的施工工艺 ,并对接口内防腐技术、底拖法海管拖运技术、海上接口技术及立管吊装技术做了详细的阐述。
The installation of subsea water injection pipeline in beach shallow sea oilfield is more complicated and difficult than that of oil pipeline. The injection pipeline is single pipe, instead of pipe in pipe usually used by oil pipeline, so the capability of resistance to wind, wave and bending is weakened largely. The design pressure is 16MPa (oil pipeline 6 25MPa), and the weld must be inner coated. This article discusses the key installing technics of injection pipeline. Some key technics are described in detail, including weld inner coat method of protected lining, bottom towing, on site tie in pre prepared by buoy to improve pipeline stress, 3D riser prefabrication, riser lifting simulated by computer.
