在层间隔离封隔器坐封并测试后，操作人员将TORRENT充填的服务工具定位在最下层的位置上来对此层进行挤压充填作业。

After the zonal isolation packers were simultaneously set and tested, the TORRENT service tool was positioned at the lowermost zone to perform the frac-pack stimulation.

因此，计算自由移动封隔器管柱的变形量是整个管柱受力分析的重要组成部分，也是保证井下作业成败的关键因素。

Therefore, the calculation on the amount of deformation is not only an important work in force analysis of packer string, but also an important factor to ensure the downhole operation.
