Finite Element Computation and Experiment Study on Expansion Force of Expandable Liner Hanger
-
摘要: 膨胀尾管悬挂器通过膨胀锥在本体内运动使其发生径向变形,依靠变形后本体与上层套管间的摩擦力,使膨胀悬挂器固定于上层套管实现尾管坐挂功能。膨胀力是膨胀锥驱动本体变形的关键、也是膨胀尾管悬挂器设计、现场施工的重要参数。采用LS-DYNA对影响膨胀力的多种因素进行研究,得到膨胀锥角、膨胀锥与本体间摩擦、膨胀本体结构对膨胀力的影响规律,并通过膨胀试验、金相观察进行验证分析。数据表明该方法能够较为准确的计算本体膨胀所需要的膨胀力及膨胀变形过程中本体的应力、应变。Abstract: Expandable liner hanger sets in the casing and hangs liners by expanding mental hanger body.Expansion force is a key technical index for liner hanger. In this paper, the key factors that affect the expansionforce such as expandable cone angle, body structure, and frictional coefficient between cone and body are computedby using LS-DYNA. And the computation results are tested nearly accurately by expansion experiments andmetallographic observation. Characteristics and rules that affect expansion force are obtained by numerical computation,which provide an important reference to choose material and optimize structural design of expandable liner hanger.
