PetroChina emergency regulation of the largest gas storage in China

The arrival of the winter heating gas peak has made PetroChina many long gas pipeline overwhelmed. November 17, "Daily economic news" from the oil learned that PetroChina for the first time this year to use the largest underground gas storage in China-Dagang reservoir gas storage group to carry out gas transfers to ensure the supply of some key cities.　　At the same time, PetroChina has begun to make a report on the two gas storage banks in the west-East gas pipeline.　　Using the largest domestic gas storage tank for November 15, Beijing gas pipeline company Dagang Reservoir Group in accordance with the Beijing Oil and Gas control center directive, the first day from the underground gas extraction nearly 5.7 million cubic meters, the second date of gas production reached about 8 million cubic meters, to protect Tianjin residents with gas. According to the Beijing Oil and Gas control center dispatching a deputy director Fan Li introduced, into the early November, the national consumption of natural gas ladder-type growth, in order to ensure the life of gas, from October 10 onwards, Shaanxi-Beijing gas transmission system, west-east gas transmission system, astringent Sebei piping system has been operating at full capacity, the pipeline network daily gas volume reached 120 million cubic meters.　　Imports of Central Asian gas have also been increased to the highest contract level.　　Dagang Gas Storage Group is an important part of Shaanxi-Beijing pipeline storage and distribution system, which consists of large-Zhang Tuo gas storage and plate 876 gas storage, plate-North gas storage, plate-South gas storage, plate 808 gas storage, plate 828 gas storage composition, bear the seasonal peak, pipeline emergency gas supply in the main line, maintain the main trunk gas balance three major functions.　　According to statistics, the reserves of Dagang Gas storage group and North China Gas storage group have reached 1.963 billion cubic meters this winter, increasing 150 million cubic meters from last year.　　In addition to the Gas Reservoir group in Dagang, the newly built North China Gas storage Group is preparing for 100 million cubic meters of gas production this winter.　　At present, the reserves of the two reservoirs are up to 1.963 billion cubic meters, an increase of 150 million cubic meters over last year.　　In response to last year's Beijing natural gas consumption peak and summer of up to 13:1 of the situation, the end of September this year, Beijing gas pipeline company to the Dagang Gas storage group in advance of one months to complete the gas injection, at present, the volume of 1.85 billion cubic meters to complete the scheduled plan 106%, to the historical extreme Cities outside Beijing have more pressure on the city. 100% of the natural gas used in Beijing is transported through the Shaanxi-Beijing pipeline.　　2009, Shaanxi-Beijing pipeline accumulated 14.4 billion cubic meters of natural gas, of which nearly half of the natural gas directly to Beijing. In recent years, the daily consumption of natural gas in Beijing is only about 4 million cubic meters, while the daily gas in winter peak is 60 million cubic meters, and the peak Valley difference is more than 10 times times.　　In order to ensure that Beijing and other key cities, PetroChina through the upstream production, from the large pipe network pumping gas guarantee. PetroChina said that the main source of Shaanxi-Beijing pipeline-changqing gas field This October began large-scale production, according to the maximum capacity to produce natural gas.　　This year, the natural gas in the Central Asian gas, Qinghai oil fields will become an important supplement to Shaanxi-Beijing pipeline gas transmission, is expected this winter will be 660 million cubic meters of imported natural gas through the West gas East line to transfer to Shaanxi-Beijing lines, astringent Sebei pipeline will also be added to Beijing in due course. However, people in the industry are alsoHeart, PetroChina pumped large quantities of natural gas into key cities in Beijing, and the gas shortages in other cities are further exacerbated. According to statistics, the amount of natural gas in Beijing this year will be increased by 18% on the basis of last year, the amount of natural gas will reach 7.6 billion cubic meters.　　In this connection, PetroChina said that to ensure the supply of other cities in the gas field is also increasing production, and the relevant gas storage is also speeding up the construction, there is a process. In addition, the west-east gas transmission Liu Zhuang Gas storage Project 10th this month has broken ground.　　Liu Zhuang gas storage is located in Jiangsu Huaian Jinhu County Chenqiiao Town.　　In order to meet the demand of seasonal peak-shaving of the first line and downstream users of west-east gas pipeline, the LNG gas storage in Rudong, Jiangsu Province, has been built in addition to the west-East gas pipeline Jintan and Liu Zhuang two gas storage depots. The construction of the Liu Zhuang gas storage project is expected July 10, 2011 to put into use.　　After putting into production, Liu Zhuang gas storage will and has been part of the production of the Jiangsu Jintan Reserve Bank, so that the west-east gas transmission line of the first line of reserves of gas in the year to reach about 300 million cubic meters. At the same time, PetroChina has begun to make a report on the two gas storage banks in the west-East gas pipeline.
