【摘要】：管道回拖是定向钻穿越的最后环节,在回拖过程中导向孔四周坚硬的岩石容易破坏管道外3PE防腐层,因此仅用传统聚乙烯热收缩带对管道进行保护是不够的。研发了耐磨性能更好的新型定向钻穿越管道保护材料。在川渝管网北外环二期工程涪江定向钻穿越工程中,首次引入了FB(Fibertec)光固化套与Strong Pipe管道定向穿越耐磨保护材料、PP-KJ光固化套及传统的聚乙烯热收缩带一同进行试拖试验。结果表明:FB光固化套耐磨性能和抗剪切性能较好,能够适应川渝地区的地质条件,较好地保护3PE层,但FB光固化套与3PE层间的粘结较弱,因此应根据工程费用选择合理的安装方式。试拖试验可用于验证管段保护材料安装方案的优劣性,同时填补了该材料在川渝管道工程中安装应用及效果检验方面的空缺。
[Abstract]:Pipeline backhauling is the last step of directional drilling. The hard rock around the guide hole can easily destroy the 3PE anticorrosive coating outside the pipeline. Therefore, it is not enough to use the traditional polyethylene thermal shrinkage zone to protect the pipeline. A new type of directional drilling pipe protection material with better wear resistance has been developed. In Fujiang directional drilling crossing project of the second phase of the North Ring Project of the Sichuan and Chongqing Pipeline Network, a new type of directional drilling material has been developed. It is the first time to introduce FBX Fibertec light curing sleeve and Strong Pipe pipe through the wear resistant protective material PP-KJ photocuring sleeve and traditional polyethylene heat shrinkage band to test the towing test. The results show that the weight FB light curing sleeve has good wear resistance and shear resistance. It can adapt to the geological conditions in Sichuan and Chongqing, and protect 3PE layer better, but the bond between FB light curing sleeve and 3PE layer is weak. Therefore, a reasonable installation mode should be selected according to the project cost. The trial towing test can be used to verify the merits and demerits of the installation scheme of the protective material in the pipe section, and at the same time fill the gap in the installation, application and effect inspection of the material in the Sichuan and Chongqing pipeline engineering.
