How to shoulder the heavy responsibility of ensuring supply in 7 provinces such as Beijing, Tianjin, Hebei and Mongolia.
Recently, a cold snap has swept through many places in China.
Words such as blizzard cooling are frequently searched.
Many friends choose to stay at home.
Make tea around the stove or have a hot pot.
Enjoy the bliss of winter.
You've been curious about natural gas for heating and cooking.
Where did it come from?
Deliver this warm winter natural gas.
It's generally not "what-as-you-go".
Natural gas that is extracted or imported.
Always send it out in a steady stream.
However, there are obvious peaks and valleys in user demand, with less summer and more winter.
Therefore, gas storage is needed as an intermediate link.
Natural gas is compressed and injected underground in the summer.
It is mined again during the peak gas consumption in winter.
In addition, gas storage is also of great strategic reserve significance.
Walking into the central control room of the Shuangtaizi gas storage, the first thing the reporter saw was a line of red words on the top of the large screen: The operation area of the Shuangtaizi gas storage has been in safe production for 809 days. Gao Xi, deputy head of the gas storage operation area, told us, "Stable operation is the first requirement of gas storage.
"Steady" has also become the most frequent word in this interview. In order to ensure that thousands of households downstream can use safe and secure natural gas, gas storage needs to quickly respond to the adjustment of gas production plans, and fulfill this promise of safety and stability with the resilience of being able to go up and down.
Fully prepare for "stability". "Harvest when ordered", this is the summary of the work during the supply guarantee period by Wang Xin, head of the operation area of Shuangtaizi gas storage. As soon as the order arrives, the gas production volume must be able to go up, which is a big test for equipment and personnel. Every year, before the start of the heating season, the gas storage does a lot of preparation.
This heating season is the year when they receive the most orders to adjust their gas production. "We're used to paying attention to the weather forecast as soon as we enter October, and we're always ready to collect gas. At most this year, three dispatch orders were given in one day, one higher than the other. Wang Xin told reporters, "We all seize the time to check the equipment at night, and find problems during the day and work with other departments to rectify them, and resolutely do not delay until the next day." ”
Advanced equipment helps "stability". Behind the strong peak regulation capability, it is inseparable from the support of a number of new technologies and equipment. In 2022, it will become the first gas storage in China to use centrifugal compressors, which not only fills the application gap in the corresponding fields in China, but also greatly increases the natural gas processing capacity of the gas storage. Today, while ensuring stable operation, the localization rate of equipment here has reached 95%.
In order to reduce the burden on employees, the Shuangtaizi gas storage is also under construction of digital and intelligent gas storage. At present, 2 unmanned aerial vehicles (UAVs) have been introduced to patrol the line, which has replaced the manual inspection of the longest 24km pipeline line, and at the same time, the internal management optimizes the patrol route, and uses more central control room instruments to observe as much as possible, and also equips the inspection personnel with a handheld methane laser detector, which can be operated on the first floor, and also reduces the stay time of employees in risky places.
The emergency plan is "stable". In the early stage of the construction of the gas storage, most of the employees had no relevant work experience, and everyone groped for the test, while summarizing and editing the operation specifications, and it took ten days of testing to solve all the problems. Since then, learning by doing has become the norm for them.
Since its official opening in 2021, new large-scale equipment has been put into operation every year. In order not to affect downstream users, the operation area not only customized the emergency response plan for the equipment one by one, but also summarized the experience after the first emergency disposal and compiled more than 80 emergency disposal cards. When some of the most advanced new equipment was put into use, Gao Xi admitted that the pressure was really high, "I had no experience to learn from, and I was all on my own to explore the control of the new system and write the rules for use." If there is an abnormality, it must be solved quickly, after all, the equipment cannot be stopped. ”
Responsibility to ensure "stability". Now in its fourth year, Ghosh has been working here since 2021 during the construction of the gas storage. Towards the end of the first phase of the gas storage construction, he had a knee operation, 8 stitches, and soon after getting off the operating table, he rushed to the scene on crutches to put himself to work.
When the reporter asked whether he had encountered "thrilling moments" in the past few years of working in the gas storage, Gao Xi waved his hand again and again, only saying that the most impressive thing was that it was put into production in the first year. On a particularly cold day, he suddenly received the task of 8 million cubic meters of gas production, he asked everyone to withdraw from the scene, and organized the central control room to slowly open the valve until he saw that the flowmeter had a reading, and his hanging heart was not put down. The next day, there was a rare heavy snowstorm, and all the employees of the station were trapped for 3 days. "The mentality is quite stable, and everyone doesn't have time to think about it, mainly because they are afraid that the situation of the new device will be unstable, and they will also be encrypted for inspection and observation. ”
In order to correct the possible errors in the data of the central control room and completely eliminate hidden dangers, the gas storage still insists on uninterrupted manual inspection twice during the day and four times at night. At 4 o'clock in the afternoon, after the first meeting, Zhao Xin and Shen Shihan, foreign operators, embarked on the first inspection of the night shift.
Along the way, Zhao Xin smoothly answered every technical question, but when talking about the Spring Festival arrangement, he paused rarely, "I have been working for 16 years, and I have been on the post for the New Year every year." My home is close, let colleagues from other places go home for the New Year. ”
Although they were familiar with this line and knew the location of each line by heart, it still took more than an hour to complete the data recording of a full circle. On the way back, the sky was snowflakes and the temperature was getting colder.
At the moment, the room is still warm, and everything in the double gas storage is still running smoothly. Behind the country's largest peak regulation capacity is the constant persistence of gas storage personnel.
