中国石油网消息：4月8日，从非洲乍得油田传来喜讯，由华北油田勘探开发研究院海外团队牵头治理的Baobab C5-14井，历经换泵施工顺利实现高效复产，已平稳生产43天，累计增油603吨，一举摘掉长期困扰其生产的“低效帽”，实现单井与区块开发效益的双重提升，为海外复杂油田低效井治理与存量资产盘活树立了新的实践标杆。

China Oil News: On April 8th, good news came from the oil fields in Chad, Africa. The Baobab C5-14 well, which was managed by the overseas team of the Exploration and Development Research Institute of North China Oilfield, successfully achieved efficient resumption of production after pump replacement construction. It has been operating stably for 43 days, with a total increase of 603 tons of oil production. This achievement has lifted the "low-efficiency cap" that had long plagued its production, achieving a dual improvement in the development benefits of individual wells and the block. It has set a new practical benchmark for the management of low-efficiency wells in complex overseas oil fields and the revitalization of existing assets.

Baobab C5-14井自2025年2月采用ESPCP泵投产后，产量长期低于区块平均水平，频繁停井，效益低下。为破解这一难题，团队坚持效益优先、一井一策，系统整合油藏动态、井筒状况、邻井生产及区域注采关系等多维度数据，对低效根源进行深入“诊断”。在此基础上，团队统筹谋划换泵改造、补孔增产、控水管柱下入等多套综合治理方案，着力系统性突破产能瓶颈、挖掘剩余油潜力、实现长效稳产。

Baobab Since the C5-14 well started production using the ESPCP pump in February 2025, its output has consistently been lower than the average level of the block, resulting in frequent well shutdowns and poor economic efficiency. To solve this problem, the team adhered to the principle of prioritizing efficiency and formulated individual strategies for each well. They systematically integrated multi-dimensional data such as reservoir dynamics, wellbore conditions, production of adjacent wells, and regional injection and production relationships to conduct in-depth "diagnosis" of the root causes of low efficiency. Based on this, the team coordinated and planned multiple comprehensive treatment solutions, including pump replacement and renovation, well re-drilling for increased production, and control of water control pipe string insertion, to systematically break through the production capacity bottleneck, tap the remaining oil potential, and achieve long-term stable production.

决策过程中，团队通过数值模拟手段，结合精细化投入产出测算，对每套方案的施工成本、预期增油量、投资回收期、实施风险等关键指标，进行逐项比对、精准评估、优中选优。经过严谨研判，排量更大、扬程更高、更适配深井供液能力的电潜泵举升方案凭借“较低投入、快速释放产能”优势胜出，成为最终治理举措。该井开井复产即见实效，日增油达14吨。

During the decision-making process, the team used numerical simulation methods and detailed input-output calculations to compare and eva luate each scheme's key indicators such as construction cost, expected oil increase, investment recovery period, and implementation risks item by item. After rigorous analysis, the electric submersible pump lifting scheme with a larger displacement, higher head, and better adaptability to deep well liquid supply capacity won out due to its advantages of "lower investment and rapid production capacity release", and became the final governance measure. The well was put back into production immediately after opening, and the daily oil production increased by 14 tons.

此次低效井的成功治理，彰显了华北油田勘探开发研究院乍得团队将技术创新与经营思维深度融合的过硬能力，为华北油田海外业务运营提供了坚实支撑。

The successful treatment of these inefficient wells has demonstrated the outstanding ability of the Chadian team of the Exploration and Development Research Institute of North China Oilfield to deeply integrate technological innovation with business thinking, providing a solid foundation for the overseas business operations of North China Oilfield.
