Core Insights - China's largest offshore gas field "Deep Sea No. 1" has successfully completed its 100th oil export since production began, achieving an annual oil and gas output of over 4.5 million tons of oil equivalent by 2025, comparable to medium-sized onshore oil fields, indicating that China's deep-sea gas field production and operation technology has reached a world-class level [1][3]. Group 1 - "Deep Sea No. 1" has completed the export of over 650,000 tons of condensate oil, with annual oil and gas output exceeding 4.5 million tons of oil equivalent for the first time [3]. - The gas field is China's deepest and most challenging deep-water gas field, with the highest geological temperature and pressure, and the largest annual gas output since its commissioning in 2021 [3][5]. - The gas field has a proven geological natural gas reserve of over 150 billion cubic meters and is developed in two phases, featuring core production facilities capable of processing and separating oil and gas offshore [5]. Group 2 - The gas field operates at a maximum working depth of over 1,500 meters and a maximum geological temperature of 138 degrees Celsius, with a current natural gas production capacity of 5 billion cubic meters per year [5]. - Daily production includes 15 million cubic meters of natural gas and over 1,600 tons of condensate oil, with a cumulative production of nearly 14 million tons of oil equivalent since its launch [5].

1月2日，记者从中国海油获悉，我国海上最大气田"深海一号"近期完成投产以来的第100船原油外输工作，2025年气田年产油气量突破450万吨油当量，与陆 地中型油田产量规模相当，标志着我国深海气田生产运维技术已经达到世界先进水平。 "深海一号"气田是我国迄今为止自主成功开发的作业水深最深、地层温压最高、勘探开发难度最大、年产气量最大的深水气田。自2021年投产以来，中国海 油现场作业团队对"深海一号"生产流程进行持续优化，探索最佳工艺参数组合，最大限度释放深水气田生产潜能，目前气田天然气年产能达到50亿立方米， 每年能从天然气中分离出产超40万吨凝析油。 "深海一号"大气田最大作业水深超1500米，地层最高温度达到138摄氏度，天然气探明地质储量超1500亿立方米，分两期项目开发建设，核心生产设施"深海 一号"能源站和"四星连珠"平台群，均具备基本的油气加工处理能力，能在海上就地完成天然气和原油气的分离和外输。 中国海油"深海一号"气田生产监督 尹燕波：我们通过海底管道和油轮将油气输送到陆地。目前，气田每天会产出1500万立方米的天然气和超过1600吨的凝 析油。投产以来，气田已累计完成了100船次凝析油外输作 ...
