China Petroleum Network news (reporter Wang Yanni, correspondent Yang Dongjie) learned from the diary on April 2 that the country's first underground gas storage reservoir, the Lama Dian Gas Storage Reservoir in Daqing Oilfield, successfully completed the task of natural gas supply last winter and this spring. It lasted for 117 days and produced a total of 90.23 million cubic meters of gas, exceeding the plan by 10 million cubic meters, and the daily output exceeded 1 million cubic meters.

During this round of winter supply, in order to cope with extremely cold weather, the La'er gas injection station system of the Lama Dian Gas Storage Reservoir in Daqing Oilfield summarizes the work experience over the years, establishes a perfect communication, coordination and emergency response mechanism, adopts a “3+1” operation and maintenance model, and strives for gas source protection to the greatest extent possible.

“In view of various production problems in the gas injection station, we must uphold the concept of lean management, strengthen the institutionalized management of the production process, and ensure that the equipment is guaranteed to the individual and the responsibility is guaranteed to the individual; we must adopt key control and encrypted inspection methods to track the operating status of the equipment, so as to achieve early detection, early analysis, and early treatment."Luo Kai, the stationmaster of the La'er Gas Injection Station of the Lama Dian Gas Storage Reservoir in Daqing Oilfield, said.

During this gas extraction cycle, the Laerji Gas injection station pays real-time attention to instantaneous flow changes in response to the actual situation in the station, well station pipelines, etc., and scientifically responds to gas volume fluctuations.Once the staff of the central control room finds that the pressure drop rate of the production well exceeds the normal range, they will communicate with the gas well inspection staff as soon as possible to deal with abnormal production conditions.At the same time, do a good job in the maintenance and maintenance of equipment such as electric heaters and tank thermal insulation, and promote the safe and stable improvement of gas production and transmission.

In the next step, the Lamadian gas storage reservoir will enter the transition period of adjustment and injection, promote equipment inspection and maintenance work, and carry out all-round maintenance of equipment and facilities in the gas injection station to ensure that all kinds of production equipment and facilities are in the best operating condition, and be fully prepared for the next round of gas injection and gas storage work.
