When the pressure at the casing shoe is lower than the babble point pressure, there is a certain proportion relation between the easing gas production and the submergence pressure as well as the easing-tubing sectional area ratio.

针对放套管气生产油井，现场测试了多口油井的套管气量，比较了考虑套管气与忽略套管气对气油比计算结果的差异，证明忽略套管气产量会给气油比计算结果带来较大偏差。

In the design of expension tool, the cone angle is the key, because it must satisfy the plastic extreme condition of the expension tube and reduce the upgoing frictional resistance of the expension cone to minimize the possibility of tool sticking. It is preferred that the material quality of expension tube must differs from that of casing and the yield limit of expension tube must be less than that of casing, which is favorable to protect casing.

在膨胀工具结构设计中，锥角设计是关键，除了要满足膨胀管达到塑性极限条件外，还应综合考虑膨胀锥上行的摩阻尽可能小，以减小工具卡死的可能；膨胀管的材质应与套管材质有差异为好，并且膨胀管的屈服极限应小于套管的屈服极限，这样有利于保护套管。

Based on finite element dynamic model of expansion casing with rubber sleeve, casing deformation and stress change inside casing, contact pressure at both sides of rubber sleeve and expansion parameter changes caused by friction factors during the expansion are analyzed.

根据带有橡胶筒的膨胀套管有限元力学模型，对套管膨胀过程中橡胶变形和套管内的应力变化、橡胶筒两侧的接触压力，以及摩擦因数引起的膨胀参数变化等做了分析研究；对橡胶筒的厚度、长度做了定量和定性分析，发现在橡胶与套管之间的接触摩擦因数作用下，橡胶过长将会在纵向产生&堆积&现象，在有限空间中，使其受较大的接触压力而失效。
