摘　　要：由于硫化氢的腐蚀性和剧毒性,环空带压井生产安全风险较大。在对含硫气井筒分析的基础上,对环空带压的类型进行了辨识、分类;结合元坝气井作业条件,完善和细化B-B test流程,建立了环空带压诊断流程;通过对长期安全需要的分析,提出了配备含硫气井安全控制设备和方案;针对对不同环空异常带压类型,进行了治理方案研究。There is plenty of risk in a production with sustained annular pressure because H2 S is corrosive and virulent. In this study, taking Yuanba gas wells as examples, we distinguish the types of sustained annular pressure, perfect the B-B test technological process, and set up diagnosis ways of annular pressure increase. Moreover, based on the demand of long-term safety, to equip with safety control facilities and to make programs are proposed for sour-gas wells. Some control schemes on various types of annular abnormal pressure increase are put forward.
