Abstract: As an important tool for maintaining wellbore integrity and achieving layered exploitation of
underground resources in well completion engineering, the reliability and stability of block sealing work are
self-evident. In ultra-high temperature and high pressure oil and gas fields, higher requirements are placed on
the temperature and pressure resistance of block seals, and there is little research in this area in China. This
article develops multiple size series of well completion block sealing tools through the development of new
high-temperature resistant airtight materials, the design of block sealing structures, and the combination of
structural simulation and experiments. This series of tools has a temperature resistance of 204 ℃ and a pressure
resistance of 10000 psi, providing domestic tool support for the development of ultra-high temperature and
high pressure oil and gas fields in China.
Key words: ultra-high temperature and high pressure; oil and gas fields; completion tools; block sealing
