2004年9月1日，随着西气东输第一站进气阀门开启，塔里木油田牙哈凝析气田生产的天然气率先涌入西气东输管道。由此，清洁的天然气穿越祖国的万里河山，源源不断地造福下游群众，推动我国全面进入“天然气时代”。随着天然气市场需求日益增长，塔里木油田着力提升天然气生产能力，全力以赴增产保供。截至2017年12月，累计向西气东输管网供气突破2000亿立方米；截至2022年3月，供气突破3000亿立方米，助力天然气在中国一次能源消费中的比重持续提升。

经测算，塔里木油田生产输送的3500亿立方米天然气，折合替代标煤4.66亿吨，相当于减排二氧化碳7.57亿吨，促进了我国东部地区特别是长三角地区能源和产业结构优化调整。

西气东输工程投产近20年来，塔里木油田先后落实了克拉-克深、博孜-大北两个万亿立方米大气区，成功开发出我国陆上最深的克深9气田、我国陆上压力最高的克深13气田等19座大中型气田。2023年，塔里木油田天然气产量再创历史新高，为下游经济社会发展、民生用气保障夯实了“底气”。

去冬今春，面对多轮寒潮和强降雪天气，塔里木油田牢牢守住民生用能底线，向西气东输管网的日供气量由2023年10月初的5000多万立方米，提升至用能高峰期的7483万立方米。

在加大增储上产力度的同时，塔里木油田持续提升供气保障能力，对连接塔里木油田各气源地和西气东输管网的重要枢纽站——西气东输第一站进行了3次扩建，将其年最大供气能力从最初的120亿立方米逐步提升至400亿立方米。

塔里木油田油气运销事业部执行董事、党委书记常桂川表示：“截至3月22日，西气东输第一站已平稳供气7142天，无一时短供，无一日断供，实现了风险百分百受控、计量百分百准确、质量百分百合格、客户百分百满意。”

On September 1, 2004, with the opening of the intake valve at the first station of West-east gas transmission, natural gas produced in Yaha condensate field of Tarim Oilfield first flooded into the West-east gas transmission pipeline. As a result, clean natural gas traverses the thousands of miles of the motherland, continuously benefiting the downstream masses, and promoting China to fully enter the "natural gas era". With the increasing demand of natural gas market, Tarim Oilfield strives to improve natural gas production capacity and go all out to increase production and ensure supply. By December 2017, the total gas supply to the west-east gas transmission network had exceeded 200 billion cubic meters; As of March 2022, the supply of natural gas exceeded 300 billion cubic meters, helping the proportion of natural gas in China's primary energy consumption continue to increase.

It is estimated that the 350 billion cubic meters of natural gas produced and transported by the Tarim oilfield is equivalent to replacing 466 million tons of standard coal and reducing 757 million tons of carbon dioxide, which promotes the optimization and adjustment of energy and industrial structure in the eastern region of China, especially in the Yangtze River Delta region.

In the past 20 years since the West-East Gas transmission project was put into operation, Tarim Oilfield has successively implemented two trillion cubic meter atmospheres, namely Kela-Keshen and Boz-Dabei, and successfully developed 19 large and medium-sized gas fields, including Keshen 9 gas field, which has the deepest onshore pressure in China, and Keshen 13 gas field, which has the highest onshore pressure in China. In 2023, the natural gas production of Tarim Oilfield reached a new record high, which consolidated the "base" for the downstream economic and social development and the people's livelihood gas security.

Last winter and this spring, in the face of multiple cold waves and heavy snowfall, the Tarim Oilfield firmly adhered to the bottom line of people's livelihood energy, and the daily gas supply of the west-east gas transmission network increased from more than 50 million cubic meters in early October 2023 to 74.83 million cubic meters at the peak of energy consumption.

In addition to increasing reserves and production, Tarim Oilfield continues to improve its gas supply capacity. The first station of West-East Gas transmission, an important hub connecting various gas sources in Tarim oilfield and the West-east gas transmission network, has been expanded three times, gradually increasing its annual maximum gas supply capacity from 12 billion cubic meters to 40 billion cubic meters.

Chang Guichuan, executive director and Secretary of the Party Committee of the oil and gas Transportation and marketing Division of Tarim Oilfield, said: "As of March 22, the first station of west-east gas transmission has been supplying gas smoothly for 7,142 days, with no short supply and no daily supply, achieving 100% control of risks, 100% accuracy in measurement, 100% qualified quality and 100% satisfaction of customers."
