摘　　要：组块密封作为完井工程中的保持井筒完整性、实现井下资源分层开采的重要工具,其工作的可靠性与稳定性不言而喻。在超高温高压油气田中,对于组块密封的耐温性、耐压性要求更高,该方面研究在国内少有涉及。本文通过新型耐高温气密材料的开发、组块密封结构设计,结合结构仿真与试验,研制形成多个尺寸系列耐温204℃、耐压10000 psi的完井组块密封工具,为我国超高温高压油气田开发提供了国产化工具支持。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.
