摘要: 膨胀套管技术是节约井眼直径的钻井新技术,现已投入实践,而在我国尚处于理论探索阶段。应用ADINA软件,建立了可膨胀管膨胀过程的力学模型.研究了在不同摩擦系数和不同膨胀幅度情况下,壁厚为8.94 mm的95/8″套管的膨胀过程,并且进行了详细的计算机模拟。通过分析、比较沿膨胀管径向不同位置处的单元节点组的位移量,得出了在不同的摩擦系数和不同的内径膨胀幅度时金属的流动规律,为膨胀芯头的结构设计和材料选择以及膨胀技术的实际应用提供了理论参考依据。

Abstract: The solid expandable tubular technology developed in t nineties of the twentieth century to saving the hole diamete and originated from the Enventure company in USA. Now t technology has been put into practice, but it is at the stage theoretic research in our country. This article established t
mechanics model of the expand process of the expandable casi with the elastic-plastic finite-element contact question of t ADINA software. Through choosing different value of the frtion coefficient and extent of expansion,the detailed compusimulation analysis of the expand process that expanded the
80 steel 95/8″tubular was done . under the foundation of quatative and quantificational comparison of axial and radial placement of the groups cell at different location along the raddirection of the tubular, gained the metal flow rules of the so expandable tubular at different value of the friction coefficie
and extent of expansion, provided theoretic fundament for tstructure design of expandable cone ,choosing material of solid expandable tubular and the practical application of the so expandable tubular technology.

Key words: casing, tubular metal flow, expansion exten computer simulation
