Hutubi Gas Storage in Xinjiang Oilfield: "Implanted" Electric Drive "Heart" Efficient Operation to Add Kinetic Energy

As of May 26, a single electric drive high-pressure centrifugal compressor with the largest displacement in China has been running safely and smoothly for one month in Hutubi gas storage in Xinjiang oil field. The addition of the compressor "new army" has increased the overall daily gas injection capacity of the gas storage tank by 10 million cubic meters, laying a solid foundation for the improvement of gas injection and production capacity of the gas storage tank and accelerating capacity to reach production.

This centrifugal compressor has a designed daily gas injection capacity of 10 million cubic meters, which is the largest compressor in the current domestic active gas storage, and is also the key equipment in the second phase of the gas storage adjustment project. With the smooth operation of centrifugal compressors, the number of compressors in Hutubi gas storage has increased to 9, the daily gas injection capacity has been greatly improved, and the daily gas injection volume has reached a record high, providing a strong power support for the safe and efficient operation of gas storage and the winter supply.

"The compressor is the power 'heart' of the gas storage production and operation. The successful operation of the centrifugal compressor is of great significance to the efficient use of Hutubi gas storage capacity of 10 billion cubic meters, the continuous improvement of peak load balancing capacity, and the acceleration of capacity expansion and expansion." Xinjiang oil field gas storage company chief engineer Xu Changfeng said. It is understood that since the Hutubi gas storage opened the 12th gas injection cycle on March 28 this year, 855 million cubic meters of gas has been injected to accumulate "energy" and add "confidence" for natural gas peak regulation this winter and next spring.

As the largest natural gas storage in China, Hutubi gas storage serves the dual functions of seasonal peak regulation and emergency gas supply in cities along the West-east gas pipeline network, as well as seasonal peak regulation in northern Xinjiang. In addition to ensuring the gas consumption of Urumqi, Changji and other cities in northern Xinjiang, the exported natural gas is also transported to Beijing, Shanghai and other cities along the west-east gas pipeline. It has played an important role in ensuring winter supply and seasonal peak regulation in northern Xinjiang and cities along the west-east gas pipeline network. At present, the gas storage has reached 10 billion cubic meters, and since it was put into operation in 2013, 22.3 billion cubic meters of gas has been injected and 18.6 billion cubic meters of gas has been extracted.
