新疆油田稠油开采井口的密封装置长期以来主要采用法兰式调偏心光杆密封器(以下简称“法兰式光杆密封器”),一直存在着密封周期短、密封效果差、井口跑油等问题。2005年,试用了QBZC-Φ25/28光杆密封器,通过现场应用评价和对比认为,QBZC-Φ25/28光杆密封器不仅弥补了现有的所有光杆密封装置的缺点,彻底地解决了井口跑油问题,而且有望成为稠油开采井口密封装置的最佳解决方案。
For a long time, the sealing device of heavy oil recovery wellhead in Xinjiang Oilfield has long adopted the flange-type offset rod light stabilizer (hereinafter referred to as “flange rod light stabilizer”). There are always some problems such as short sealing period, poor sealing effect and running oil in the wellhead . In 2005, the QBZC-Φ25 / 28 polished rod sealer was tried out. According to the field application evaluation and comparison, the QBZC-Φ25 / 28 polished rod sealer not only made up for the shortcomings of all existing polished rod sealing devices, Problem, and is expected to be the best solution for a wellhead seal in heavy oil production.
