摘　　要：利用有限元分析软件,对采油树在不同温度和不同压力油气作用下的稳定性进行了分析,重点分析了流体场-温度场-应力场多物理场耦合下采油树最大内压和最大形变的变化。结果表明:采油树油气流体场可以等效为稳定的压力和温度;油气压力与采油树最大形变呈线性关系,压力每升高2 MPa,最大形变增加0.4 mm;采油树最大内压和最大形变都随着油气温度呈线性关系,油气温度每升高40 ℃,采油树最大形变增加约0.37 mm。The stability of the tree under various oil and gas pressure and temperature conditions was examined using finite element analysis software,with particular attention paid to changes in the maximum internal pressure and maximum deformation of the tree under the coupling of the fluid field,temperature field,and stress field.The findings demonstrate that stable pressure and temperature can be equated with the oil and gas fluid sector.The maximum deformation of the tree and oil and gas pressure have a linear connection;for every 2MPa rise in pressure,the maximum deformation increases by 0.4mm.The maximum deformation of the tree increases by approximately 0.37 mm when the oil and gas temperature rises by 40℃.The maximum internal pressure and maximum deformation of the tree are both linear with the oil and gas temperature.
