BYJ型防喷脱接器的设计与应用

DESIGN AND APPLICATION OF BYJ MODEL BLOWOUT CONTROL UNIT

本文介绍了BYJ型防喷脱接器的结构和工作原理。它既有抽油杆与大泵活塞脱接功能,又能实现不压井作业施工,是大型抽油泵理想的配套工具。现场应用表明,该防喷脱接器对接成功率较高,并实现了大泵井不压井施工。

<ABSTRACT> This paper presents the structure and working mechanism of B Y J Model blowout control unit which not only can connect the sucker rod with the pump pilston, but can also be snubbing serviced. It is an ideal complete set of pumping unit. Field application shows that the success ratio of connecting this unit is high and can be operated by snubbing service.
