| 摘 要： | 钻柱振动失效控制装置通过曲率段时会发生较大的弯曲变形、承受较大的弯曲应力，本文建立了组合钻具受力变形分析的三维有限元模型，应用ANSYS软件的大变形、接触非线性理论，对不同曲率井段的钻具强度进行了评估，为井下钻具的通过能力评价提供了新的研究方法。

| Abstract: | Drillstring vibration control device will occur bending deformation and bear greater bending stress through the curvature. Three-dimensional finite element model in the paper is established to analyze the load and the deformation of bottom hole assembly(BHA) with large deformation and non-linear contact theory of ANSYS software. The strength of BHA is evaluated at different curvature and a new passing ability assessment study method is provided. |

| Keywords: | curvature bottom hole assembly bending stress passing ability |
