Abstract

Abstract: 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.

Key words: rotary control head, seal equipment, underbalance drilling, design
