祖国需要就是前进的方向！ 长庆油田55载砥砺奋进书写能源报国壮美答卷

Core Viewpoint - The Changqing Oilfield has achieved significant milestones in oil and gas production over its 55-year history, becoming China's largest oil and gas field and contributing substantially to the country's energy supply [1][4]. Group 1: Historical Development - In 1970, thousands of oil workers began exploration in the arid region of Longdong, facing extreme challenges due to the deep and dense oil and gas resources [3]. - The first generation of workers established the foundation for oil and gas exploration using rudimentary tools, leading to the breakthrough in production in 1979 when annual crude oil output surpassed 1 million tons [3]. - The discovery of major gas fields, such as Sulige, positioned Changqing as a key player in national natural gas supply [3][4]. Group 2: Production Milestones - By 2013, the annual oil and gas equivalent production exceeded 50 million tons, and by 2020, it reached 60 million tons, marking a new milestone in China's petroleum industry [4]. - The cumulative oil and gas output from Changqing could fill 80 West Lakes, and it supplies approximately 25% of the national natural gas production [4]. Group 3: Technological Innovations - Significant advancements in technology have been made, particularly in shale oil and coalbed methane development, with the establishment of the first domestic shale oil production area capable of producing over 10,000 tons per day [6]. - The discovery of the Mengshan coalbed methane field has opened new avenues for exploration, with the successful drilling of a 2,500-meter horizontal well setting records in China [6]. Group 4: Sustainable Practices - The integration of smart technology in oil and gas production has improved operational efficiency, allowing remote management of over 100,000 oil wells and pipelines [7]. - The implementation of renewable energy sources, such as over 2,600 solar power stations, has contributed to significant carbon reduction efforts, equivalent to the carbon absorption of 54 million trees [7].
