Summer injection winter harvest, lamadian gas storage this task is done very well

The gas storage is like an “underground bank”. The gas is injected in summer and extracted in winter, which plays a role of peak cutting and valley filling.Lamadian gas storage in Daqing oilfield is the first underground gas storage in China. There are 13 Wells of gas injection and extraction, with a total of more than 2 billion cubic meters of gas injection and extraction, which effectively guarantee the people’s gas consumption in Longjiang.Not long ago, Lamadian Gas Storage successfully completed the winter supply protection task, lasting 107 days, the gas production exceeded 100 million cubic meters, the highest gas production since the establishment of the storage, and the effect of supply protection and peak regulation is more prominent.Lamadian gas storage is safer and more intelligent because of its long running time and serious aging of equipment.In the first half of last year, the reconstruction of Lamadian gas storage was completed. Four compressor units were updated, operation standards were improved, and safety risks were eliminated.In particular, it has improved the fire protection system and enhanced the security capability.At the same time, the central control room has digital integrated operation, automatic unit control system, digital operation and maintenance, automatic inspection and other functions, the gas storage continues to move forward to intelligent operation.They also reserve a new technology — hot nitrogen purge anti-freezing blocking technology, mainly used in single well pipeline frozen blocking treatment, can effectively solve the problem of winter gas production frozen blocking.In December last year, the peak heating gas supply increased sharply.In order to meet the demand of supply protection in winter and relieve the pressure of pipe network, lamadian gas storage was put into full operation, and all 13 gas Wells were opened.In order to ensure the smooth operation of the gas production device, the staff of Lamadian gas storage encrypted the inspection frequency, increased the regular inspection frequency from 2 hours to 1 hour, and added inspection points such as buffer tank, distributor trunk line, flowmeter tracing belt, so as to ensure that the key parts affecting gas production are covered as much as possible.During the gas production cycle, they dealt with 45 times of freezing and plugging of single well pipelines and 98 times of freezing and plugging of main lines, with a maximum daily gas production of 1 million cubic meters.The comprehensive “physical examination” will usher in the gas injection period after the gas recovery period, lamadian gas storage is expected to start gas injection in late April.They seize the early, scientific development of gas injection scheme, gas well production process into gas injection process for strict control, gas injection machines, instruments, safety valves and other devices for a comprehensive “physical examination”, to ensure stable and efficient facilities and equipment.On this basis, the ability of problem analysis and prediction is improved, parameters are adjusted reasonably according to temperature and pressure vibration values, and problems found during gas production are sorted out and summarized to avoid the repetition of similar problems and make full preparations for a new round of gas injection task in summer.At present, the equipment maintenance, pipeline maintenance and parameter adjustment of the gas storage are in full swing, laying a solid foundation for the smooth progress of gas injection work this winter.Text 〡 Daqing Daily all media reporter Zhang Xingfu picture 〡 correspondent Zhang Lei Huang Yue Wang Jianpeng statement: this article copyright belongs to the original author, if there is a source error or infringement of your legitimate rights and interests, you can contact us through the mailbox, we will be timely processing.Email address: jpbl@jp.jiupainews.com
