摘要
对钢套管分级技术进行了研究,减小了套管回旋下压钻进侧摩阻力,优化了套管材质和壁厚等参数,解决了在施工期间穿越深埋高承压水和深厚松软土地基成桩难的问题。
The classification technology of steel casing is studied,which reduces the friction resistance of the drilling side of the casing,and optimizes the parameters of the casing material and wall thickness. It has solved the problem that it is difficult to pass through deep buried high pressure water and deep soft soil foundation during construction.
