摘　　要：为研究鹅颈管在钻井液环境下的冲蚀行为以及表面强化效果的评价方式,通过有限元仿真分析方法研究了钻井液密度对鹅颈管冲蚀行为的影响以及内腔表面强化评价方法。结果表明:鹅颈管的弯管内径冲蚀速率最大,随着钻井液密度变高最大冲蚀速率也变大,但最大冲蚀速率仍发生在弯管内径。鹅颈管内腔经过表面强化之后可以有效降低最大变形位移,最大可降低34.23%。可见钻井液密度对鹅颈管的冲蚀行为影响不可忽视,表面强化能够有效降低最大变形位移。In order to study the erosion behaviour of the gooseneck pipe in the drilling fluid environment and the evaluation of the surface strengthening effect,the influence of the drilling fluid density on the erosion behaviour of the gooseneck pipe and the evaluation method of the surface strengthening of the inner lumen were investigated by the finite element simulation and analysis method.The results show that:the erosion rate of gooseneck pipe is the largest in the inner diameter of the bend,and the maximum erosion rate becomes larger with the density of drilling fluid becoming higher,but the maximum erosion rate still occurs in the inner diameter of the bend.The maximum deformation displacement can be effectively reduced by 34.23%after surface strengthening of the inner lumen of the gooseneck pipe.It can be seen that the effect of drilling fluid density on the erosion behaviour of the gooseneck pipe cannot be ignored,and surface strengthening can effectively reduce the maximum deformation displacement.
