中国石油网消息：告别热水站燃气锅炉持续燃烧与碳排放困扰，大庆油田迎来清洁能源替代的关键突破。5月30日，大庆油田首个“光热+”联合供热系统已平稳运行15天，把阳光变成了油田作业的“绿色热源”。

China Oil News: After overcoming the persistent burning and carbon emission problems of gas boilers in hot water stations, Daqing Oilfield has achieved a key breakthrough in the replacement of traditional energy sources with clean energy. On May 30th, the first "photothermal +" combined heating system of Daqing Oilfield has been operating stably for 15 days, converting sunlight into a "green heat source" for oilfield operations.

目前，该系统集热阵列运行平稳，集热效率、供热稳定性均达到预期，年光热替代率正稳步向48%以上设计目标推进。项目投用后，已开始为大庆油田采油三厂北二一热水站提供清洁热源，初步实现了对传统燃气锅炉供热的替代，预计年可提供清洁热量1.3万吉焦，节约天然气51.1万立方米，节约标煤671.76吨，减少二氧化碳排放1102.7吨，可满足约3000井次热洗作业用热需求。

At present, the solar heating array of this system is operating smoothly, and the heat collection efficiency and heating stability have reached the expected levels. The annual solar thermal substitution rate is steadily advancing towards the design target of over 48%. After the project is put into use, it has begun to provide clean heat sources for the North 21 Hot Water Station of the Third Oil Production Plant of Daqing Oilfield. It has initially achieved the replacement of traditional gas-fired boilers for heating, and is expected to provide 13,000 gigajoules of clean heat annually, saving 511,000 cubic meters of natural gas, 671.76 tons of standard coal, reducing carbon dioxide emissions by 1,102.7 tons, and can meet the heat demand of approximately 3,000 well cleaning operations.

作为油田生产的重要环节，油井热洗作业需要持续稳定的高温热源。过去，北二一热水站为洗井水罐车提供热水的任务完全依赖燃气锅炉，每年需消耗100多万立方米天然气，不仅生产成本高，更伴随着大量碳排放。如今，这一传统用能模式被彻底改变——新投运的“光热+”联合供热系统通过捕捉太阳能，为水罐车提供稳定、清洁的热水，大幅降低天然气消耗与碳排放，实现了从“燃烧天然气”到“收集阳光”的根本性转变。

As an important part of oilfield production, the hot washing operation of oil wells requires a continuous and stable high-temperature heat source. In the past, the North 21 Hot Water Station relied entirely on gas boilers to provide hot water for the water tank trucks, consuming over 1 million cubic meters of natural gas each year. This not only resulted in high production costs but also led to significant carbon emissions. Now, this traditional energy consumption model has been completely transformed - the newly launched "Photothermal +" combined heating system captures solar energy to provide stable and clean hot water for the water tank trucks, significantly reducing natural gas consumption and carbon emissions, achieving a fundamental shift from "burning natural gas" to "collecting sunlight".

该项目创新构建了“集热—补能”智慧能源系统，打造了一套高效协同的地面“阳光能源系统”。99组线性菲涅尔集热器与22组槽式集热器组成集热阵列，集热器占地面积1.2万平方米，总集热面积达3694平方米，集热总功率1.28兆瓦，如同地面阳光收集器精准捕捉太阳能。系统全程智能化运行，配备高精度太阳追踪技术，可实时调整角度，高效吸收光能；所获热能通过导热油传递，直接用于生产。当遇到阴天或夜间等太阳能供应不足时，站控系统自动启动备用加热炉补能，实现24小时不间断稳定供热。

This project innovatively constructed a "heat collection - energy replenishment" smart energy system, and created a highly efficient and collaborative ground-based "solar energy system". 99 linear Fresnel collectors and 22 trough-type collectors formed a heat collection array. The collector area was 12,000 square meters, with a total heat collection area of 3,694 square meters and a total heat collection power of 1.28 megawatts. It is like a ground-based solar collector precisely capturing solar energy. The system operates throughout the process in an intelligent manner, equipped with high-precision solar tracking technology, which can adjust the angle in real time and efficiently absorb solar energy. The obtained thermal energy is transmitted through heat transfer oil and directly used for production. When there is insufficient solar energy supply, such as on cloudy days or at night, the station control system automatically starts the backup heating furnace for energy replenishment, ensuring 24-hour uninterrupted and stable heating.

作为大庆油田首个大规模光热应用项目，该系统的运行并无成熟经验可循。采油三厂监督管理中心统筹协调，联合安全、质量等多部门组建专项工作组，协同攻克技术与管理难题。安全监督室坚持“关口前移、全程盯防”原则，针对高处、吊装、动土等高风险作业建立“问题清单”，形成了一套“因段施策”的监督网络，为项目安全推进扫清障碍；质量监督室以技术规格书为依据，严控施工质量，对焊口实行100%无损检测，确保工程高标准推进。如今，集控室内通过电脑即可完成整套设备的智能操作与实时监控，实现了智能调控，大幅提升了管理效能。

As the first large-scale photothermal application project of Daqing Oilfield, the operation of this system has no mature experience to follow. The Supervision and Management Center of the Oil Production No.3 Plant coordinated and coordinated with multiple departments including safety and quality to form a special working group to jointly overcome technical and management challenges. The Safety Supervision Office adhered to the principle of "moving the control point forward and monitoring throughout the process", established a "problem list" for high-risk operations such as heights, hoisting, and excavation, and formed a set of "measures tailored to each section" supervision network to clear obstacles for the safe progress of the project; the Quality Supervision Office based on technical specifications, strictly controlled the construction quality, implemented 100% non-destructive testing on welds, and ensured the project was advanced to a high standard. Now, in the centralized control room, the entire set of equipment can be automatically operated and monitored in real time through computers, achieving intelligent control and significantly improving management efficiency.

“这不仅是一次技术上的突破，更是管理模式和用能方式的双重革新。”大庆油田新能源事业部生产管理科科长张垒说，大庆油田将系统总结项目建设经验，形成标准化技术方案和管理流程，推动更多绿色能源项目落地，为传统油气田高质量发展注入持续“绿动力”。

"This is not only a technological breakthrough, but also a dual innovation in management models and energy utilization methods." Zhang Lei, the director of the Production Management Department of the New Energy Division of Daqing Oilfield, said. Daqing Oilfield will systematically summarize the project construction experience, form standardized technical solutions and management processes, and promote the implementation of more green energy projects, injecting continuous 'green power' into the high-quality development of traditional oil and gas fields.
