To date, the natural gas purification plant at the Puguang Gas Field of Sinopec’s Zhongyuan Oilfield has conducted multiple tabletop simulations of 19 maintenance plans and 22 construction plans in advance, striving to provide technical support for the shutdown for maintenance and technological upgrades in May. 　　It is reported that, in light of the challenges such as short maintenance periods, heavy workload, numerous concurrent tasks, and concentrated labor needs, the natural gas purification plant advances its preparation work from four aspects – organization, technology, construction, and materials – following the principle of acting as early as possible and being as meticulous as possible. “We started working in advance on the maintenance and technical upgrades, aiming to carry out all preparatory tasks with utmost care and precision, so as to secure a double guarantee of timely progress, quality, and adherence to deadlines for the upcoming 25-day shutdown for major maintenance of the gas field. ”Zhang Wenbin, a leading expert in natural gas purification plants, said. 　　Last June, the plant prepared documents such as the \"Technical Plan for Shutdown and Restart of the Purification System during the Major Overhaul of the Puguang Gas Field in 2022\" and the \"HSE Assurance Plan for Shutdown Overhaul\", to provide technical support for the shutdown for maintenance purposes. At the beginning of this year, the factory established an organization for maintenance and technical upgrades, which included three working groups responsible for maintenance of utility systems, maintenance of flare systems, and upgrading of control systems. Led by top experts, these teams carefully reviewed the plans and kept making improvements to them. 　　To ensure the successful completion of the shutdown for maintenance on schedule, the natural gas purification plant made coordinated arrangements and worked closely with 17 contractors, including the Oil and Gas Processing Technology Service Center of Zhongyuan Oilfield, Zhongyuan Oilfield Construction Company, and the Water Services Branch. It refined the maintenance schedule, carried out detailed safety and technical briefings in advance, assigned personnel and equipment to each contractor, and carefully prepared daily action plans from the perspectives of safety, quality, and progress. It also developed a detailed four-level scheduling plan, breaking down the workload down to specific hours and individuals. 　　At the same time, the factory strictly controls access for personnel entering the site. Starting from March, it organized 3 batches totaling 940 people to undergo training on obtaining the necessary permits to work there, ensuring that the construction workforce is available in a timely manner. The factory also actively coordinates with the Materials Support Department to monitor the progress of material procurement and ensure timely supply of materials. 　　“At present, we are mobilizing human and material resources to carry out comprehensive risk assessment in three phases: suspension of production, construction, and resumption of production. We are carefully identifying the difficulties and risks involved, and formulating countermeasures for each issue based on their urgency and importance. ”said Li Yongsheng, the director of the natural gas purification plant.
