摘要
永久式封隔器完井技术是通过下入带有永久式封隔器的完井管柱隔离油套,实现分层开采或保护套管长期开采的完井技术。四川磨溪龙王庙组气藏是目前我国最大的单体海相整装气藏,气藏具有高温、高压、高产、高酸性等特点,为保证气藏长期安全生产,文章针对永久式封隔器完井技术的特点,从完井工具选择、完井管柱设计、完井工艺特点等方面进行优化,在龙王庙气藏的开发井成功应用,形成了能够在"三高"气井完井推广应用的永久式封隔器完井技术。
Permanent packer completion technology is a kind of well completion method,it can realize selective zone production and casing protection. The Longwangmiao gas reservoir is the biggest monomer marine gas reservoir in China,it is characterized by high pressure and high temperature,high- volume withdrawal,and high sour gas reservoir. In order to ensure production safety,according to the features of permanent packer completion technology,the completion tool was optimized and completion pipe string was redesigned,the permanent packer completion technology suited for'three high ' reservoir was formed and applied successfully in Longwangmiao gas reservoir.
