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 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。
Only the hidden trouble existing in the testing stage has been considered in designing the casing program for the high temperature and high pressure well, can the casing safety be guaranteed.
在对高温高压井进行井身结构设计时必须考虑测试期间存在的隐患，才能保证套管安全。
