摘要
针对大口径管道穿越过程中存在的问题,对钻杆在穿越过程中的受力状况进行理论分析;建立有限元模型,利用有限元法分析水平定向钻管在回拖过程中钻具的应力和应变等问题,讨论存在的问题并提出相应的改进技术.
As to the problems in the process of large diameter pipeline crossing, the stress state of drill pipe in the crossing process is analyzed in theory. The finite element model is built and the stress and strain of the drilling pipe during horizontal directional drilling are analyzed using finite element method. The existing problems are discussed and the corresponding technical innovation is put forward.
