摘　　要：在分支井井眼连接总成三维建模的基础上,选择了机构材料及机械性能参数,确定了分支井井眼连接总成仿真分析方法,利用ICEM对模型进行网格划分,用有限元软件对预成形过程进行非线性仿真,并给出了位移、应力、应变、危险截面、路径分析等重要的相关参数仿真结果,为其现场应用提供参考依据,并对分支井预成形中的关键问题提出了建议。Based on the three-dimensional modeling of multilateral junction assembly, designating the material and the mechanical property parameter and determining the multilateral well simulation method, the three dimensional model was meshed with ICEM and the nonlinear simulation of multilateral well preliminary forming process was carried on with the finite element commercial software. As the result, the important related parameter simulation result was obtained such as the displacement, the stress, the strain, the dangerous section, the path analysis, and this could provide the reference foundation for practical application. Finally, a proposal to the key question in the multilateral well preliminary forming process was proposed.
