摘要
某天然气管道定向钻穿越易出现的问题是防腐层易损坏、成孔难。采用光固化保护套保护防腐层,合理控制钻进液以保证成孔。
The problems of directional drilling crossing of a natural gas pipeline are that the anticorrosive layer is easy to be damaged and the hole is difficult to be formed.The light-curing protective sleeve is adopted to protect the anticorrosive layer,and the drilling fluid is reasonably controlled to ensure the hole formation.
