摘要
近年来,定向钻穿越已在我国广泛运用。为防止定向钻穿越段管道外防腐层在穿越过程中受到损伤,通过对现有定向钻施工工艺、外防腐层防腐性能及现场实际情况进行分析,提出了可行的定向钻穿越管道外防腐层保护方案,在实际运行中取得了较好的效果,为定向钻穿越中对外防腐层的保护作了有益的探讨。
In recent years,directional drilling crossing technique has been widely used in China.In order to avoid external anticorrosive coating in gas pipeline from being damaged during directional drilling crossing,a feasible protection scheme is put forward after analysis on present drilling crossing construction techniques,corrosion control performance of external anticorrosive coating and actual conditions in construction site,which is efficient in actual operation.
