摘要:: 大口径、长距离、复杂地层情况下的异径双管定向钻穿越工程的施工难度极大。文章从工程风险分析、施工难点分析与控制、施工现场情况、施工经验总结等方面,论述了通过控制穿越的整体曲线质量、成孔孔径和孔内钻屑的泥浆携带等因素,成功地实施了穿越的过程。
Crossing construction of double pipelines with different diameters using directional drillingtechnique in the conditions of large pipe diameter, long-distance and complex stratums is a very difficult task.The project of pipeline crossing Paraiba do Sul River has been successfully fulfilled by controlling wholecrossing curve quality, bore aperture and mud carrying drilling cuttings. The engineering risks and difficultconstruction points are analyzed and controlled. The field construction practice and experience are summarized.
