本文主要针对目前抽油机井口密封部分存在的问题,利用密封和纠偏原理,研制出一种便捷防偏抽油机光杆密封装置。该装置主要适用于油田抽油机井井口的密封和纠偏。同时还有解决密封盘根装卸困难的问题,给油井的生产运行带来很多便利。 This paper mainly aims at the existing problems in the wellhead sealing part of the pumping unit. By using the principle of sealing and deviation correction, a light bar sealing device of the hand-held piston pump is developed. The device is mainly suitable for oil well pumping wellhead seal and correction. At the same time, there is also the problem of solving the difficult packing packing operation, which brings a lot of convenience to the production and operation of the oil well.
