Abstract: Wellintegrity technology can effectively ensure the safety of the entire life cycleof oil and gas wells. With the exploration and development of more and morehigh-temperature, high-pressure, high-yield and deep wells, and the constantlyincreasing requirements for safety and environmental protection in variouscountries, well integrity technology has become a research hot spot in the oilindustry. Based on the analysis of the four basic concepts of well integrity:full life cycle, well integrity management system, well barrier, and riskassessment, this article conducts a comparative analysis of the developmenthistory of well integrity technologies at home and abroad, and systematicallysummarizes foreign wells. The current status of integrity technology, based onthe above investigation and analysis, puts forward suggestions for the nextdevelopment direction of well integrity technology, which has certain guidingsignificance for the development of the integrity of the next step.
