摘要

摘要: 日益复杂的油气井钻采条件使得油井管柱面临越来越苛刻的载荷工况，油井管接头作为整个管柱的薄弱环节，其失效问题非常突出。实物实验费用昂贵、实验周期长，且复杂载荷工况难以施加，无法满足实际要求。该文基于油井管接头三维全尺寸弹塑性有限元分析，构建了复杂载荷下油井管接头数值仿真平台，是实物实验的一个有力补充。该仿真平台所得极限工作扭矩与API标准提供数据基本吻合（零轴向力条件下），同时具有分析复杂工况条件下油井管接头三维力学特性的能力。通过该仿真平台，能很好地描述复杂载荷作用下油井管接头的受力特征，快速、全面地评估复杂载荷作用下油井管接头的连接强度和密封性能，明确油井管接头的极限载荷工况。

Abstract: With the exploration of oil and gas sources moves further to greater depths and into harsher environments, the working condition of pipe string becomes increasingly severe. As the weakest part of the string, the failure of threaded connections occurs frequently. Full-scale experiments are costly, time consuming and complex loads are difficult to apply. Based on three-dimensional elasto-plastic finite element analysis, a numerical platform for threaded connections is developed, which is a powerful complement to physical experiments. The calculated ultimate working torque of threaded connections by the numerical platform is consistent with the data in API standard (without axial tension). Furthermore, the numerical platform can be used to analyze the three-dimensional mechanical properties of threaded connections under complex loads. The numerical platform can evaluate the structural and sealing integrity of threaded connections accurately, and determine the load limits of threaded connections.
