摘要
根据影响稠油热采封隔件密封性能的因素,设计出能在高温高压下持久和间歇密封的7ZTS-Ⅰ型封隔件。阐述了结构特点、材质选择和工作原理。试验表明,7ZTS-Ⅰ型封隔件的坐封力为200～250kN,解封载荷为29.4～39.2kN,能满足现场作业要求。
In accordance with the factors influencing the sealing ability of the pack-off element for thermal recovery wells, Model 7ZTS-Ⅰ pack-off element is developed for both permanent and intermittent seal under high temperature and high pressure. The design features, material selection and operating principle of the element are expounded.Test shows that the setting force of the element is 200-250 kN and the releasing force is 29.4-39.2 kN.
