旋转控制头密封装置研究

旋转动密封装置是旋转控制头轴承总成的关键部件，其性能好坏直接影响旋转控制头的使用寿命。在分析旋转控制头密封现状的基础上，针对目前旋转控制头密封装置存在的主要问题，设计出了一种能够满足不同工况条件下的新型旋转控制头密封装置，该密封能够实现随井底压力变化自动调整组合密封装置密封压力的要求，实现浮动密封，从而提高了旋转控制头密封装置的可靠性和使用寿命。

Research of Seal Equipment of the Rotary Control Head

As the key part of the rotary control head's bearing assembly, the capability of the rotary dynamic seal equipment effects on the using life of the rotary control head. According to the existing problems of the rotary control head, the design of the new rotary control head on the basis of status analysis was described. This new equipment can be used in different pressure and self-correct seal pressure along with the pressure in the bottom of the well. The using life of the seal equipment was increased and its security was improved.
