全力保障珠三角供气安全 发挥“南气北送”市场保供作用

发布于:2018-12-20 14:37

10月31日,国家“天然气互联互通”重点工程——广州压气站压缩机增输工程建成投产。
 
On October 31, Guangzhou Compressor Increase Transport Project, the national key project of "Natural Gas Interconnection" was completed and put into operation.
 
 
 
2011年以来,西气东输先后在广东省建成西二线干线、广深支干线、广南支干线等多条大口径长输天然气管道,管道总里程达到831公里。截至10月31日,西气东输已累计向广东省内分输天然气250亿立方米,惠及8个城市31个下游用户。
 
Since 2011, the West-to-East Gas Pipeline has built several large-caliber long-distance natural gas pipelines in Guangdong Province, such as the Second West Line, Guangzhou-Shenzhen Branch and Guangnan Branch, with a total mileage of 831 km. As of October 31, the West-to-East Gas Pipeline has delivered 25 billion cubic meters of natural gas to Guangdong Province, benefiting 31 downstream users in 8 cities.
 
 
 
广州压气站增输工程作为今冬明春天然气互联互通保供的民生工程之一,是国家发改委重点协调推动的重点工程项目。这项工程是在原西二线广州站预留空地上新增两台18兆瓦电驱压缩机组,增输后输气能力将由每年100亿立方米增加到141亿立方米,工程配套新建110千瓦电源(双回路长度共70千米)及站内变电所。工程于今年3月开工。
 
As one of the livelihood projects for the interconnection of natural gas in this winter and next spring, Guangzhou Gas Compressor Station is a key project coordinated and promoted by the National Development and Reform Commission. This project is to add two 18 MW electric drive compressor units to the reserved space of Guangzhou Station on the second West line. After the increase, the gas transmission capacity will be increased from 10 billion cubic meters to 14.1 billion cubic meters per year. The project will be supported by a new 110 kilowatt power supply (70 kilometers of double circuit length) and substation in the station. The project started in March this year.
 
 
 
 
 
10月17日至22日,广州站进行压缩机试运前的19个动火点的二级动火作业,完成了100多道焊口的焊接工作。17日开始全站天然气放空,氮气置换。18日正式动火。23日现场19个动火点所有焊口均检测合格,随即开始天然气置换。置换合格后,压缩机启动,进行压缩机防喘振测试。25日开始全站升压,并排除新增工艺管线的泄漏点。26日启动压缩机进行24小时增压测试。30日压缩机全面完成24小时性能测试。
 
From October 17 to 22, Guangzhou Station carried out the second-stage ignition operation of 19 ignition points before the compressor commissioning, and completed the welding work of more than 100 welds. On the 17th, the whole station began to empty natural gas and replace nitrogen. Official fire on the 18th. On the 23rd, all welding joints of 19 ignition points were qualified, and natural gas replacement began immediately. After the replacement is qualified, the compressor is started and the anti-surge test of the compressor is carried out. On the 25th, the whole station boosted and the leak point of the new process pipeline was eliminated. On the 26th, the compressor was started for 24-hour turbocharging test. The compressor has completed 24-hour performance test on the 30th day.
 
 
 
这项工程建成后,不仅可以增强天然气资源调配的灵活性,保障供需平衡,实现天然气的有序利用,而且能够确保广东地区气源在冬季发挥“南气北送”市场保供作用,也保障了珠三角的供气安全,可全面改善广东省能源结构和环境。
 
After the completion of this project, not only can the flexibility of natural gas resource allocation be enhanced, the balance of supply and demand be ensured, and the orderly utilization of natural gas be realized, but also can ensure that the gas sources in Guangdong play the role of "South-to-North Gas Delivery" market in winter, as well as the safety of gas supply in the Pearl River Delta, which can comprehensively improve the energy structure and environment of Guangdong Province.
 
 
 
多元化体系助力冬季天然气供应
 
Diversified System Helps Winter Natural Gas Supply
 
 
 
随着环保力度不断加大,我国天然气需求快速增长。截至8月底,今年我国天然气表观消费量累计达1804亿立方米,同比增长18.2%。鉴于去年的经验,今年各方已采取多项措施,力求从供给端和需求端保证用气平稳顺利。在大力提升国内天然气产量的同时,我国也在积极建立多元化海外供应体系。海关总署最新数据显示,我国1月至9月天然气进口同比增长34%,至6478万吨。国际能源署署长法提赫·比罗尔预计,到今年12月前,中国将超过日本,成为全球最大的天然气进口国。
 
With the increasing efforts of environmental protection, the demand for natural gas in China is growing rapidly. By the end of August, the apparent consumption of natural gas in China totaled 180.4 billion cubic meters this year, an increase of 18.2% over the same period last year. In view of last year's experience, this year, various parties have taken a number of measures to ensure smooth gas use from both the supply side and the demand side. While vigorously promoting domestic natural gas production, China is also actively establishing a diversified overseas supply system. According to the latest data from the General Administration of Customs, China's natural gas imports from January to September increased 34% year on year to 64.78 million tons. Fatih Birol, director of the International Energy Agency, predicts that by December this year, China will overtake Japan as the world's largest natural gas importer.
