摘要
结合定向钻在沿海滩涂地区大直径管道的施工,分析施工过程中的难点问题(钻机抗拉力差,钻杆的套管开裂,淤泥层导向下沉)和应对措施。
Combined with the construction of large-diameter pipeline in coastal beach areas by directional drilling,the difficult problems in the construetion process(such as poor drilling rig tension strength,casing cracking of drill pipe,guiding sinking of silt layer)and countermeasures are analyzed.
