水泥塞密封性能的可靠评估需要在代表井下条件的高温和压力条件下进行测试。在完整的论文中，描述了为此目的设计的两个实验室设置。在这两种设置中，塞子都在钢管内部的井下条件下进行固化和测试。使用该设备，发现界面应力累积量与凝固水泥塞对气体流动的密封性能之间存在很强的正相关性。

Reliable evaluation of cement-plug sealing performance requires testing under elevated temperature and pressure conditions representative of downhole conditions. In the complete paper, two laboratory setups designed for this purpose are described. In both setups, plugs are cured and tested under downhole conditions inside sections of steel pipe. Using this equipment, a strong positive correlation was found between the amount of interfacial stress buildup and the sealing performance of the set cement plug against gas flow.
