摘　　要：含硫气井中的硫化氢与二氧化碳对油管、套管产生电化学腐蚀，严重地威胁着气井的生产，完井方法选择不当也会加剧这种腐蚀。通过国内外调查，推出了一种生产封隔器永久完井的方式，可以防止油管、套管腐蚀和减少完井作业工作量，应大力推广这种完井方式。文中对完井方式和多种工艺技术进行了探讨。H 2Sand CO 2 in sour gas well causes electrochemical corrosion of tubing and casing which greatly affect the production of gas well ,what's more,the unproper selection of completion method will worsen the corrosion.Through investigati-ng at home and abroad ,a permanent completion method by probuction packer is proposed out ,which can prevent the corrosion of tubing and casing ,and reduce t-hecompletion operation.
