摘要
油套管螺纹连接的密封性对高压气井、储气库井的安全生产和长期运营有决定性的作用。通过对油套管螺纹气密封及气密封检测的机理研究,研制成功油套管螺纹连接气密封检测装备,创新性地提出非同时解封理念,设计出系列的双封隔器检测工具,集成创新形成了适合我国的油套管螺纹连接气密封检测工艺技术,开展了10余口井的现场技术服务,为高压气井、储气库长期安全平稳的运行提供了技术支持。
Airtight property of tubing-casing thread connection has a decisive effect on work safety and long-term operation of high-pressure gas well and gas storage depot.The airtight inspection equipment for tubing-casing thread connection was successfully developedon the basis of the research on tubing-casing thread airtight and airtight inspection mechanism.The concept of non-simultaneousdecontamination was innovatively put forward while a series of double-packer detection tools were designed.The airtight inspecting processtechnology for China's tubing-casing thread connection was developed on the basis of innovative integration.The equipment has been usedon the field in service of more than 10 wells,providing technological support for long-term operational safety and stability of high-pressuregas wells and gas storage depots.
