今年前5个月，中国石油华北油田统筹推进稳油增气、绿色转型等重点工作，生产经营保持稳健态势，完全成本、操作成本等核心指标硬下降，实现储量有效益、产量有质量、发展可持续。

In the first five months of this year, the North China Oilfield of China National Petroleum Corporation comprehensively promoted key tasks such as maintaining oil production and increasing gas output, as well as green transformation. The company's production and operation maintained a stable trend, with significant reductions in core indicators such as total cost and operating cost. It achieved effective reserves, high-quality production, and sustainable development.

低成本发展远不止于简单的压缩开支，而是需要一场深度融合技术、管理与战略的系统性变革。华北油田锚定以“全员、全要素、全过程、全方位”压降成本为核心的低成本战略，突出“两利五率”“四个关键核心指标”导向，强化“提质增效”“绿色低碳”“数智转型”协同，确保降本不降质、降本不减安全，持续提升价值创造能力。

Low-cost development is not merely about simply cutting expenses; it requires a systematic transformation that integrates technology, management and strategy. The North China Oilfield has set a low-cost strategy centered on "cost reduction for all personnel, all elements, all processes and all aspects", highlighting the orientation of "two benefits and five rates" and "four key core indicators", strengthening the synergy of "quality improvement and efficiency enhancement", "green and low-carbon" and "digital and intelligent transformation", ensuring that cost reduction does not compromise quality or safety, and continuously enhancing the ability to create value.

增加经济可采储量是实现低成本战略的核心。华北油田坚持质的有效提升和量的合理增长，牢固树立“以SEC储量为核心”的价值导向，统筹考虑储量、产量、效益关系，将效益要求贯穿勘探部署、方案设计、工程实施全流程，确保大幅增加经济可采储量。强化勘探与开发协同联动，勘探上聚焦优质储量发现，突出“四新”领域风险勘探，从源头控制低效储量占比，开发上严把方案设计效益关，强化全生命周期成本管控与全流程节点优化，形成储量增、成本降的良性循环。在投资和预算管理上，坚持严谨投资、精准投资、效益投资，建立从勘探到开发的统一排队优选机制，做实做细经济评价，推进项目多方案优选和动态跟踪，对预期效益不达标的项目坚决调整，让每一分投资都落在“刀刃”上。

Increasing the economically recoverable reserves is the core of achieving a low-cost strategy. The North China Oilfield adheres to the effective improvement in quality and the reasonable growth in quantity, firmly establishing the value orientation of "taking SEC reserves as the core", comprehensively considering the relationship between reserves, production and benefits, and integrating the requirements for benefits throughout the entire process of exploration deployment, scheme design and engineering implementation, to ensure a significant increase in economically recoverable reserves. Strengthening the coordination and collaboration between exploration and development, in exploration, focusing on the discovery of high-quality reserves, highlighting the risk exploration in the "four new" fields, controlling the proportion of inefficient reserves from the source, and in development, strictly controlling the benefits of scheme design, strengthening the cost control throughout the entire life cycle and optimizing the nodes in the entire process, forming a virtuous cycle of increased reserves and reduced costs. In investment and budget management, adhering to rigorous investment, precise investment and benefit-oriented investment, establishing a unified queuing and selection mechanism from exploration to development, doing practical and detailed economic eva luations, promoting the multi-scheme optimization and dynamic tracking of projects, and resolutely adjusting projects with unmet expected benefits, ensuring that every investment is placed on the "sharp edge".

完全成本是反映油田盈利能力的重要指标。华北油田以业财深度融合为抓手，加强内外部深度对标，全链条全要素“打开分析”成本构成，精打细算投入产出比，推进成本精益化管控。一方面对措施方案开展“技术可行性”与“经济有效性”一体化论证，压降低效无效作业。另一方面优化措施结构，把水驱这个最经济有效的手段用到极致，今年注水井措施占比提升至46.7%，压裂、大修等大型措施占比降至12.4%，吨油措施费用下降的同时，阶段措施有效率提升至89%。此外，通过开展精细油藏描述、推进老油田压舱石工程和提高采收率工程等老区内部挖潜举措，老区存量资源有效盘活，效益开发水平持续提升。

Total cost is an important indicator reflecting the profitability of an oilfield. The North China Oilfield takes the deep integration of business and finance as the starting point, strengthens internal and external in-depth benchmarking, conducts "open analysis" of cost composition throughout the entire process and all elements, carefully calculates the input-output ratio, and promotes cost lean management. On one hand, it conducts integrated technical feasibility and economic effectiveness demonstrations for the measures plans, reducing ineffective and inefficient operations. On the other hand, it optimizes the measure structure, maximizing the use of water drive, which is the most economical and effective method. This year, the proportion of water injection well measures increased to 46.7%, while the proportion of large-scale measures such as fracturing and major overhauls decreased to 12.4%. The cost per ton of oil decreased while the efficiency of stage measures increased to 89%. In addition, through the implementation of detailed reservoir description, the promotion of the anchor project in old oilfields and the improvement of recovery rate projects, the existing resources in the old areas were effectively revitalized, and the level of efficient development continued to improve.

新能源转型是提升综合效益的关键抓手。华北油田加快油气与新能源业务深度融合、协同增效，统筹推进清洁能源耦合联动开发，为低成本发展注入绿色动力。依托油区井场、站场、屋顶等存量资源，筛选28座站场打造低碳示范区，规模化布局光伏、风电项目，让闲置空间产生绿色价值。同时，持续优化用能结构，通过“以电替电、以电替热、以热替热”等清洁替代模式，用新能源技术反哺传统油气生产。华北油田巴彦分公司应用电蓄热混凝土储热项目，原油集输供热综合成本下降约44%，井场生产清洁替代率超91%；留路油田推进余热梯级利用、累计发电量达46万千瓦时；任丘15万千瓦风电项目完成首台风机吊装，项目投产后年均可提供清洁电能约3.2亿千瓦时，所发绿电优先通过绿电交易回购，并参与电能量现货交易，实现生态效益与经济效益同步提升。

The transition to new energy is a key leverage for enhancing overall efficiency. The North China Oilfield has accelerated the deep integration and synergy of its oil and gas business with new energy, and is comprehensively promoting the coupled and coordinated development of clean energy. This has injected green power into the low-cost development. Leveraging the existing resources such as well sites, stations, and rooftops in the oil area, 28 stations have been selected to create low-carbon demonstration zones. Large-scale photovoltaic and wind power projects have been deployed to generate green value from idle spaces. At the same time, the energy consumption structure has been continuously optimized. Through clean substitution models such as "electricity replacing electricity, electricity replacing heat, and heat replacing heat", new energy technologies are used to support traditional oil and gas production. The Baian Branch of the North China Oilfield has applied the electric heat storage concrete heat storage project, reducing the comprehensive cost of crude oil gathering and transportation by approximately 44%, and the clean substitution rate of the well site production exceeds 91%. Liuliu Oilfield has promoted the multi-level utilization of residual heat and has accumulated a total of 460,000 kilowatt-hours of electricity generation. The 150,000-kilowatt wind power project in Renqiu has completed the hoisting of the first wind turbine, and after its commissioning, it can provide approximately 320 million kilowatt-hours of clean electricity per year. The green electricity generated will be repurchased through green electricity trading and participate in the spot electricity trading, achieving simultaneous improvement of ecological and economic benefits.
