摘    要:为了得到可靠的套管插接节点设计参数,采用ANSYS有限元程序建立了非线性有限元模型,对考虑接触影响时套管插接节点承载力进行了数值分析,分析了相关结构参数对节点承载力的影响。结果表明:管节点承载力及刚度均随套管长径比和主、套管长度比的增大而增大;主管与套管厚度相等时管节点承载力最大;管间间隙0.5~2.0 mm范围内改变主、套管直径配合对管节点承载力影响不大。

关 键 词:套管节点  非线性分析  承载力  接触

Abstract:A nonlinear finite element model was established and numerical analysis of casing plug joints of steel tubular was performed by the ANSYS software.The law of load capability was investigated by changing the ratio of diameter and length(l/d) and the ratio of the casing length and the main tube length(l/L),respectively.The influences of the casing thickness and the gap between main tube and casing for the load capability were also analyzed.The results indicated that the load capability and stiffness of the joint were both increased with the increases of both ratios of the l/d and the l/L.When the main tube thickness is equal to casing thickness,the load capability of joints will be the best.In terms of the gap between the main tube and casing,the results indicated the effect of the gap of 0.5-2.0 mm on the load capability is not prominent.
Keywords:casing plug joint  nonlinear analysis  load-carrying capability  contact
