摘要
在油气管道外防腐层外增设保护层,可防止在定向钻穿越施工的回拖过程中外防腐层被破坏。介绍3种保护层(环氧玻璃钢保护层、石夹克保护层、光固化套保护层)的结构及材料,对3种保护层的技术性能进行了比较。
Adding protective layer on external anticorrosion coating of oil and gas pipeline can protect the external anticorrosion coating from damage of pul- ling back in directional drilling crossing. The struc- tures and materials of three types of protective layers including epoxy glass fiber reinforced plastic, rock jacket and light-curing protective sleeve are intro- duced, and their technical performances are com- pared.
