摘要：

针对等井径膨胀管技术的难点——成形后螺纹接头处的结构完整性，对膨胀工艺中膨胀锥锥角对螺纹接头成形性能的影响进行研究。选取孪生诱发塑性（TWIP）钢为膨胀管材料，利用有限元软件ABAQUS，模拟大膨胀率（20%）膨胀管螺纹接头的成形过程，分析了膨胀锥锥角对成形后螺纹接头所需膨胀推力、内部残余应力情况和螺纹齿间间隙的影响。研究结果表明：锥角为10°时，所需膨胀推力最小；不同锥角情况下，螺纹接头内残余应力分布基本相同;在母螺纹根部以及螺纹齿相互接触的位置，有应力集中现象；锥角为7°和9°时，螺纹接头内的残余应力情况较好；锥角为7°和8°时，螺纹齿间间隙数值较低。

For the structure integrity of thread joint after forming, which is a difficult technique in mono-diameter expandable tubular, the influence of expansion cone angle on the formability of thread joint in the expansion process was studied. The steel TWIP was selected as material of expandable tubular, and the expansion process of expandable tubular thread joint under the expansion ratio of 20% was simulated by using finite element software ABAQUS. Furthermore, the influences of expansion cone angle on the required expansion force, the residual stress and the clearance between thread teeth were analyzed. The results show that the required expansion force is the smallest with the cone angle of 10°, and the distribution of residual stress inside thread joint is basically same under different cone angles. However, there are stress concentrations at contact position between thread root and thread teeth, and the residual stress in the thread joint is in better condition with cone angles of 7° and 9°, and the clearance between thread teeth is lower under cone angles of 7° and 8°.
