ABSTRACT: 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.
