| 摘 要： | Y441B型双向锚定封隔器是一种单卡瓦及锥体锚定式封隔器，它利用液压坐封、提放管柱解封。由于设计有坐封平衡机构，解决了因下接头与和心管分开、受力不平衡而造成在坐封的同时自动解封的问题。此外，设计有承压平衡室，改善了工作时的受力状态；采用单面螺纹步进锁紧机构，提高了封隔器坐封和密封的可靠性。因采用单卡瓦双锥体锚定方式，解决了下锥体用主动机械力脱卡的技术难题。

| Abstract: | Model Y441B double anchoring packer is a single-slip double-cone packer, which adopts hydraulic setting and pipereleasing. By means of a setting balanceing mechanism, the problem of automatic releasing in setting is solved. A pres-sure balancing chamber is designed to improve the force condition of the packer in operation; a single-side thread steplocking mechanism is adopted to improve the setting and sealing reliability. |
