摘要
自由移动封隔器管柱是油气井封隔器完井的一种重要类型 ,在油气井封隔器管柱完井工艺中 ,井内压力、温度、流体发生变化后 ,自由移动封隔器管柱变形量计算是该封隔器管柱受力分析中十分重要的工作 ,是保证安全成功地进行完井作业的关键。文中对该封隔器管柱变形的有关问题进行了分析 ,对管柱变形量计算公式进行了推导和讨论 ,并给出了算例。
The free movement packer string is an important type of Packer completion.In well completion technology of oil-gas wells with packer string,after the pressure,temperature and fluid have changed,the calculation of amount of deformation of free movement packer string is an important work in force analysis of packer string.This paper analyses the problems about deformation of this packer string,and deduces the calculation equation of amount of deformation of this kind of string,and provides,calculation examples.
