Abstract: In recent years, with the rapid development of gas field production and construction, the contractor team has fully participated in various links such as production and operation, service assurance, etc. of the production unit. And the safety and environmental protection risks and safety management risks brought by it have also been involved in the enterprise management and production site. At the same time, with the continuous improvement of the national two laws, the requirements for safety and environmental protection have increased year by year. With the increasing difficulty in the supervision of the contractor team, how to institutionalize and standardize the management of contractors by gas production units has become the core and difficulty of safety management. Therefore, grass-roots units of gas production must continue to explore, practice, summarize and consolidate, and finally propose a "1+4+N" contractor safety management mode which effectively promotes the safe, efficient, and harmonious development of grass-roots units of gas production.

Key words: contractor management, integrated operation, four security management, N multi-dimensional guarantee
