The stage where the volume pumped places the influx inside the casing shoe (the shoe line), is important as well but has not been included in these basic phases in well control.
泵入体积将侵入挤入管鞋内这一阶段是个十分重要的阶段，但不包括在井控的这几个基本阶段。
The reason for this is that the occurrence of this stage could happen before or after the end of phase I depending on the distance the influx has to travel before it enters the casing shoe.
其理由是依据侵入进入套管鞋前必须运行的行程，该阶段可能发生在I阶段之前或之后。
The float shoe prevents reverse flow, or U-tubing, of cement slurry from the annulus into the casing.
