1平方公里，用正常步速走完一个边长只需要10多分钟。大港油田新能源集团公司却在这1平方公里的空间建成了大能量场。

One square kilometer. At a normal walking pace, it would take only about 10 minutes to walk along one of its sides. However, the New Energy Group of Dagang Oilfield has managed to create a large energy field within this 1 square kilometer area.

这里有6类光伏电站、4种共计6628块光伏组件；这里让2口中深层地热井重生，可满足1平方公里区域的冬季全部供热需求；这里实现了碳中和，每年减碳2450吨。从这1平方公里起步，大港油田建成了中国石油京津冀地区最大的集中式光伏电站……

Here are 6 types of photovoltaic power stations and 4 kinds of a total of 6,628 photovoltaic modules; here, two deep geothermal wells have been rejuvenated, which can meet the entire winter heating demand for an area of 1 square kilometer; here, carbon neutrality has been achieved, with a reduction of 2,450 tons of carbon emissions annually. Starting from this 1 square kilometer area, the Dagang Oilfield has built the largest centralized photovoltaic power station in the Beijing-Tianjin-Hebei region of China Petroleum...

“公司2021年开始布局新能源业务。这1平方公里‘试验田’，不到3年便拿下碳中和认证，托举起油田转型的希望。”新能源集团公司经理赵博说。这1平方公里如何构建低碳转型的样板？9月上旬，记者走进这片“小天地”。

In 2021, the company began to lay out its new energy business. This 1-square-kilometer "experimental field" obtained the carbon neutrality certification in less than 3 years, thus holding up the hope for the transformation of the oilfield. Manager Zhao Bo of the New Energy Group Company said. How was this 1-square-kilometer area constructed as a model for low-carbon transformation? In early September, reporters entered this "small world".

地上“追光”：小空间怎么把电发足，把设备守好？

"Spotlight on the Ground": How to Ensure Adequate Electricity Supply and Safeguard Equipment in Small Spaces?

靠的不是占地广，而是抠得细；不是老经验，而是从头学

It's not about having a large territory, but about being meticulous; it's not relying on old methods, but starting anew.

大港油田勘探开发近60年。在老油田发展新能源，第一道坎就是“没地”。

The Dagang Oilfield has been engaged in exploration and development for nearly 60 years. When developing new energy sources in an existing oilfield, the first hurdle is "lack of land".

“我们这里空间不大，能用的只有屋顶和少量空地，那就每一寸都不能闲着。”新能源集团公司三级工程师马超说。

"Our space here is quite limited. All that can be utilized are the roof and a small amount of open area. So every inch of it must be put to good use." said Ma Chao, a third-level engineer of the New Energy Group Company.

3年前，园区新能源业务刚启动，由于屋顶承重有限，常规光伏设备装不上去。为了找“非常规”的设备，团队跑了5个厂家、对比了十几套方案，最终敲定厚度仅3毫米、重量只有常规光伏组件1/5的柔性光伏组件。

Three years ago, when the new energy business of the park was just launched, due to the limited roof load-bearing capacity, conventional photovoltaic equipment couldn't be installed. In order to find "unconventional" equipment, the team visited five manufacturers, compared more than a dozen schemes, and finally settled on a flexible photovoltaic module with a thickness of only 3 millimeters and a weight only 1/5 of that of the conventional photovoltaic module.

轻有轻的好，但轻也有轻的难。马超介绍，换作常规组件施工，同等体量一般只需7至10天，而这10处屋顶、1.2兆瓦装机容量的柔性光伏组件，他们花了1个月，硬是给“手搓”出来了。

There are advantages to being light, but there are also difficulties. Ma Chao explained that if the construction were carried out using conventional components, it would typically take 7 to 10 days for the same volume. However, for these 10 roof sections and the 1.2-megawatt flexible photovoltaic components, they spent one month painstakingly "handcrafting" them.

如今，这里落地了屋顶柔性光伏、地面支架光伏、光伏车棚、光伏电梯，4种技术、6类电站、6628块组件，总装机规模达3.11兆瓦，边边角角全用上了。

Nowadays, here have been installed various technologies such as flexible roof photovoltaic, ground-mounted photovoltaic, photovoltaic car shelters, and photovoltaic elevators. There are 4 types of technologies, 6 kinds of power stations, 6,628 components, with a total installed capacity of 3.11 megawatts. Every corner has been utilized.

装好设备，电发出来了。但真正难的，是让这6628块板子稳当当地用起来。

The equipment was installed and electricity was supplied. But the real challenge was to make these 6,628 boards function properly.

“都是电，能有啥不一样？”2023年，刚从变电站转岗做光伏运维时，值班员曹雪峰和同事们自信满满。直到一台逆变器因柳絮堵塞风机导致过热保护，几个老电工查了一天也没查出原因，才明白“室内变电那套，搁光伏这儿不好使了”。

"It's all electricity. How could there be any difference?" In 2023, when the on-duty operator Cao Xuefeng was transferred from a power substation to be in charge of photovoltaic maintenance, he and his colleagues were full of confidence. It wasn't until one inverter overheated due to willow catkins blocking the fan that several veteran electricians spent a whole day trying to figure out the cause, only to realize that "the indoor power substation system doesn't work here in the photovoltaic field."

老经验行不通，就从头摸索。

If the old methods don't work, then start from scratch and explore anew.

——出去学。公司送员工去酒泉学光伏运维，去杭州学无人机巡检，去南京学后台监控……

-- Go and learn. The company sends its employees to Jiuquan to learn about photovoltaic operation and maintenance, to Hangzhou to learn about unmanned aerial vehicle inspection, and to Nanjing to learn about back-end monitoring...

——私下补。不少员工利用业余时间“加餐”。班长谌庆带头自学光伏原理。曹雪峰、那振军、高晓钢追着厂家问，拉着同行聊。

-- Secretly, they made up for it. Many employees used their spare time to "make up for it". Team leader Chen Qing took the lead in self-studying the principles of photovoltaics. Cao Xuefeng, Nan Zhenjun and Gao Xiaogang chased after the manufacturers to ask questions, and chatted with their peers.

——一起磨。雨季不清洗、春天多清灰……一条条细则，都是在边干边试、边试边记中慢慢磨出来的。

-- All done together. During the rainy season, no cleaning was done; in spring, more dust was removed... Each specific rule was gradually formulated through trial and error, with notes made along the way.

3年下来，他们写了1万字的设备操作规程、42万字的运行细则，配套做出操作卡，远程监控分级报警系统也上线了。如今，大港油田31座光伏电站陆续实现无人值守。仅园区这一块，年发电量就突破390万千瓦时。

Over the course of three years, they have written 10,000 words of equipment operation procedures, 420,000 words of operation details, and have also developed operation cards. The remote monitoring and hierarchical alarm system has also been put into use. Currently, 31 photovoltaic power stations in Dagang Oilfield have successively achieved unmanned operation. In this single park area alone, the annual power generation has exceeded 39 million kilowatt-hours.

地下“储热”：老井怎么出新能？

Underground "Heat Storage": How Can Old Wells Generate New Energy?

靠的不是另起炉灶，而是清洁替代，废弃老井也能变成热源接续

It's not about starting anew, but about cleaning up and replacing. Even old wells can be transformed into heat sources and reused.

9月11日，地热运维班组员工陈虎和吴学军蹲在DG-04井、DG-21井旁，盯着仪表盘上跳动的数字。“地层温度变化得控制在2摄氏度以内，不然地热井的寿命就受影响了。”陈虎边操作边说，“就这2口井，一采一灌，每天能出175吉焦热量，冬天够整个园区取暖了。”

On September 11th, Chen Hu and Wu Xuejun, members of the geothermal operation team, stood beside the DG-04 well and DG-21 well, staring at the fluctuating numbers on the instrument panel. "The temperature of the strata should be controlled within 2 degrees Celsius. Otherwise, the lifespan of the geothermal wells will be affected," Chen Hu said as he operated. "Just these two wells, one for extraction and one for injection, can produce 175 gigajoules of heat every day. It's enough to heat the entire park in winter."

这2口井是1986年打的采暖水井，上世纪90年代被关停，一“睡”就是近30年。2023年，园区筹划新能源业务时，发现它们还保留着矿权。“把能利用的资源都利用起来。”地热运行分公司副经理黄平向记者解释，通过论证、试验，最终唤醒了这2口井。

These two wells were drilled as heating water wells in 1986. They were shut down in the 1990s and have been dormant for nearly 30 years. In 2023, when the park was planning for new energy business, it was discovered that they still held mining rights. "Make full use of all available resources," explained Huang Ping, the deputy manager of the Geothermal Operation Division, to the reporter. Through research and experiments, these two wells were eventually awakened.

“地热井也解决了‘这边发着绿电、那边用煤烧着锅炉’的尴尬。”赵博说。让老井重新吐出热来，靠的不仅是设备，更是这群老石油人不服老的那口气。“为了让井重新焕发活力，我们这群‘老家伙’可没少‘遭罪’。”吴学军说。

"Geothermal wells have also resolved the awkward situation of 'producing green electricity here while burning coal in boilers there'." Zhao Bo said. Reviving the old wells to release heat not only depends on equipment, but also on the indomitable spirit of these veteran oil workers. "To make the wells regain their vitality, we 'old-timers' have suffered a lot," Wu Xuejun said.

2023年11月，DG-04井刚完成中深层地热改造，水从地下抽上来，裹挟着大量气体，管线晃得厉害。他们轮流手动排气，3天3夜，井口没断过人。设备刚稳住没几天，又赶上春节前深井泵出现故障，园区供暖暂停。3根电缆缠住了泵体。风雪里，员工们不敢使劲硬拽，一点一点地松、一点一点地点提。8个小时，赶在除夕前3天恢复了供暖。

In November 2023, after the DG-04 well completed the mid-deep geothermal transformation, water was pumped up from underground, carrying a large amount of gas. The pipeline shook violently. They took turns manually venting the gas. For three days and three nights, there was no break at the wellhead. The equipment had just stabilized for a few days when, before the Spring Festival, the deep well pump broke down, and the park's heating was suspended. Three cables were wrapped around the pump body. In the snow and wind, the employees dared not pull hard; they slowly loosened and lifted little by little. After 8 hours, the heating was restored three days before the New Year's Eve.

“井老了都能出热，人老了咋就不能干新活？”黄平拍拍胸脯说。

"Even an old well can produce heat. Why can't an old person do new things?" Huang Ping patted his chest and said.

这套地热系统现在实现“采灌平衡”，消耗1千瓦时的电，能换来4.5千瓦时电产生的热量。一个供暖季，可替代标煤666吨，减碳1589吨。

This geothermal system is now achieving a "balance between extraction and injection", meaning that for every 1 kilowatt-hour of electricity consumed, it can generate 4.5 kilowatt-hours of heat. During a heating season, it can replace 666 tons of standard coal and reduce carbon emissions by 1589 tons.

从“一口井”到“一片热源”，经验也在不断外溢。3年时间，他们借鉴园区地热井的修复经验，让另外4口中深层废弃老井重新上岗。大港油田全域再添9座浅层冷热联供项目，成为集团公司规模最大的浅层地热群。从老井盘活到地热站点建设，这支队伍在实践中攒下了大量的现场经验，逐步摸透油田地域条件下地热开发的一套实操方法。眼下，他们正优化4万平方米供热区域的开发方案，把地热往周边辐射。

From "a well" to "a heat source", the experience has been continuously spreading. Over a period of three years, they drew on the restoration experience of the geothermal wells in the park and made four other deep-abandoned old wells resume their operations. The entire Dagang Oilfield has added nine shallow geothermal cold and heat supply projects, becoming the largest shallow geothermal cluster of the group company. From revitalizing old wells to the construction of geothermal stations, this team has accumulated a large amount of on-site experience in practice and gradually mastered a set of practical methods for geothermal development under the conditions of the oilfield area. Currently, they are optimizing the development plan for a 40,000-square-meter heating area and radiating geothermal to the surrounding areas.

云端“算能”：看不见的碳怎么算清？

Cloud-based "carbon accounting": How to accurately calculate invisible carbon emissions?

靠的不是经验估算，而是数智赋能，把每笔碳账都变成转型依据

It is not based on empirical estimation, but on digital intelligence empowerment. Every carbon account is transformed into a basis for transformation.

电有了，热有了，但减了多少碳、省了多少钱，不能靠感觉。

Electricity is available, and heat is available, but how much carbon has been reduced and how much money has been saved? These cannot be determined by intuition.

园区监控大屏前，马超和技术人员盯着不断跳动的数据曲线，讨论着智慧管控系统升级方案。“以前靠人跑现场、翻台账，发现问题慢；现在系统就能‘喊人’了。”马超说。可刚接触这套智慧管控系统时，大家并不轻松。系统不仅要管发电，还要算碳账。

In front of the large screen for monitoring in the park, Ma Chao and the technicians were closely observing the constantly fluctuating data curves and discussing the upgrade plan for the intelligent control system. "Previously, we had to go to the site and check the ledgers manually to identify problems, which was very slow. Now, the system can 'call for help' for us," said Ma Chao. However, when they first came into contact with this intelligent control system, it was not an easy task. The system not only needed to manage power generation but also calculate carbon accounts.

要把碳账算明白，先得搞清楚算什么。园区里500多名员工的办公用车、食堂用能、冬季供暖、生产运行等数据，都要统一纳入碳核算体系。

To accurately calculate the carbon account, one must first clarify what to calculate. Data such as the office vehicles used by over 500 employees in the park, energy consumption in the cafeteria, winter heating, and production operations must all be uniformly incorporated into the carbon accounting system.

“最难的不是算，而是把账凑齐。这些数据来源分散、口径不一，有的在纸上，有的在不同系统里。”新能源研究中心技术人员安海敏说，“碳虽看不见，但不能不算；正因为看不见，才必须算得更准。”

The most challenging part is not the calculation itself, but collecting all the data. These data sources are scattered and have different measurement standards. Some are on paper, while others are in different systems. According to An Haimin, a technician from the New Energy Research Center, "Although carbon is invisible, it cannot be ignored; precisely because it is invisible, we must calculate it more accurately."

——先翻家底。面对数据分散的硬骨头，团队耗时3个月，一项一项地校准、一条一条地核实，统一口径，最终将零散数据归拢成了一本可追溯、可核验的碳账本。

— Start with the basics. Faced with the tough challenge of scattered data, the team spent three months calibrating item by item and verifying one by one, standardizing the data and finally integrating the scattered data into a traceable and verifiable carbon ledger.

——账清手就准。找到了碳的出处，才知道先掐哪头、再压哪头。减排从来不是各家平摊，而是一笔一笔算出来的、一克一克抠出来的。底数摸透了，发力点也就准了：全电厨房改用光伏绿电，地热供暖全面替代燃煤锅炉，连原本耗电的电梯加装系统后都能边运行边发电。

— Once the accounts are settled, the work proceeds smoothly. After identifying the sources of carbon emissions, it becomes clear which end to cut first and which end to compress next. Emission reduction is never an even distribution among all parties; it is achieved through detailed calculations and gradual reduction of one gram at a time. Once the facts are clarified, the focus becomes clear: the all-electric kitchen switches to green power from photovoltaic sources, geothermal heating completely replaces coal-fired boilers, and even the elevator system that originally consumed electricity can generate electricity while operating.

2024年4月，园区拿到碳中和认证，成为大港油田首个在运维层面实现碳中和的示范区。

In April 2024, the park obtained the carbon neutrality certification and became the first demonstration area in the operation and maintenance process of Dagang Oilfield to achieve carbon neutrality.

“园区每年2450吨的减排量，摊到整个油田并不多。”新能源集团公司副经理高华民说，“但它把技术投入和减排之间的关系摸清了，让油田绿色转型有了可复制的模板。”

"The park achieves an annual emission reduction of 2,450 tons. When spread out across the entire oilfield, this amount is not significant," said Gao Huamin, the deputy manager of the New Energy Group Company. "However, it has clarified the relationship between technological investment and emission reduction, providing a replicable template for the green transformation of the oilfield."

依托园区智慧管控平台积累的绿电数据与调度经验，大港油田把绿电交易做大了，省间绿电现货交易累计超过320万千瓦时。

Based on the green electricity data and dispatching experience accumulated through the park's intelligent control platform, Dagang Oilfield has expanded the green electricity trading volume. The cumulative inter-provincial green electricity spot trading has exceeded 3.2 million kilowatt-hours.

如今，这个1平方公里的“样板间”正成为燎原星火。越来越多内外部企业前来交流取经，园区的宝贵经验，正源源不断地被更多兄弟单位推广复制。

Nowadays, this 1-square-kilometer "model area" is becoming a blazing example that inspires others. More and more internal and external enterprises are coming to learn from it. The valuable experience of this park is being continuously promoted and replicated by more sister units.
