摘要

Well integrity technology can effectively ensure the safety of the entire life cycle of oil and gas wells. With the exploration and development of more and more high-temperature, high-pressure, high-yield and deep wells, and the constantly increasing requirements for safety and environmental protection in various countries, well integrity technology has become a research hot spot in the oil industry. Based on the analysis of the four basic concepts of well integrity: full life cycle, well integrity management system, well barrier, and risk assessment, this article conducts a comparative analysis of the development history of well integrity technologies at home and abroad, and systematically summarizes foreign wells. The current status of integrity technology, based on the above investigation and analysis, puts forward suggestions for the next development direction of well integrity technology, which has certain guiding significance for the development of the integrity of the next step.
