摘　　要：随着油气井生产年限日益增加,油气井安全风险凸显,为了保障油气井安全运营,实现油田长期高产、稳产,需要定期对油气井完整性进行风险分析。根据海上油气井井筒完整性理论,对东方1-1气田XX井进行了现场环空压力测试,并根据测试结果对该井井屏障现状进行评估,进而得出该井的井分类结果。研究表明:评估结果符合现场实际,可以为后期井的维护、治理提供参考依据。With the increasing production life of oil and gas Wells,safety risks of oil and gas Wells become prominent.In order to ensure safe operation of oil and gas Wells and achieve long-term high and stable production of oil fields,risk analysis of oil and gas well integrity needs to be conducted regularly.In this paper,based on the well integrity theory of offshore oil and gas Wells,the field annular pressure test was conducted on well XX of dongfang 1-1 gas field.Based on the test results,the well barrier status was evaluated,and the well classification results were obtained.The research shows that the evaluation results are in line with the field practice and can provide reference for the later maintenance and management of well.
