新型CND光敏玻璃钢预浸带在定向钻穿越的应用

Application of New CND Photosensitive Glass Fiber Reinforced Plastic Prepreg Tape in Directional Drilling through

定向钻穿越工艺以其优越的穿越性能和精度,广泛应用于公路、铁路、大中型水域等难度较高的穿越施工中。根据定向钻施工工艺,管道外防腐层在管道回拖工序施工中容易受损,导致管道外防腐层破损,丧失部分防腐功能,减少管道使用寿命。本文介绍一种新型CND光敏玻璃钢预浸带材料,在穿越管道外防腐层外增设一层光敏玻璃钢保护层,应用于复杂地层定向钻穿越中,保证穿越管道外防腐层的完整性。

Due to its superior traversing performance and precision, directional drilling traversing technology is widely used in difficult traversing constructions such as highways, railways, and large and medium-sized waters. According to the directional drilling construction process, the outer anti-corrosion layer of the pipeline is easily damaged during the construction of the pipeline back-to-back process, resulting in damage to the outer anti-corrosion layer of the pipeline, loss of part of the anti-corrosion function, and shortening the service life of the pipeline. In this paper, a new type of CND photosensitive glass fiber reinforced plastic prepreg material is introduced. A layer of photosensitive glass fiber reinforced plastic protective layer is added outside the anti-corrosion layer of the crossing pipeline.
