Research on Bellows Sealing Technology and the Application in Geological Drilling Field

Abstract:

The bellows technology has been successfully used for sealing in drilling engineering and also can be used to deal with many complicated down-hole conditions. It is considered to be one of the core technologies in drilling industry. According to the geological drilling and field test conditions of bellows sealing, and based on the introduction of bellows technology, the paper analyzed its application feasibility in geological drilling industry and the key technical issues.
