中国石油网消息：9月13日，在冀东油田南堡作业区的注水站内，高压泵组高效运转，清澈的处理水正源源不断地注入千米地层。这是该油田推进精细注水体系落地见效的一个缩影。

China Oil News: On September 13th, within the water injection station of the Nanbao operation area in the Hejiadong Oilfield, the high-pressure pump set was operating efficiently, and clear treated water was continuously being injected into the thousands of meters deep strata. This is a snapshot of the oilfield's efforts to implement the precise water injection system and achieve its intended results.

今年年初以来，冀东油田将“能量为基、注水为本”的理念深植于每一口井、每一道工序，从源头水质净化到注水精准调控，一条环环相扣的精细注水链条正在为老区稳产注入强劲动能。

Since the beginning of this year, the Jidong Oilfield has deeply ingrained the concept of "energy as the foundation and water injection as the core" in every well and every process. From the purification of source water quality to the precise regulation of water injection, a tightly connected chain of meticulous water injection is injecting strong impetus for the stable production of the old oilfield.

冀东油田技术人员从油藏特性、井筒状态到地面设备进行全方位逐井排查，制定差异化对策，确保水井“扶得起、稳得住”。同时，优化生产运行机制，从严规范开关井的审批流程，加快冬关井的复产工作。针对措施井作业可能引发的注水波动问题，技术人员提前两三个月预判梳理工作量，科学统筹关井时序，将注水时率同比提升0.7个百分点，用稳固的“底盘”确保整个注水系统全天候运转。在此基础上，通过落实注水设备分包责任制、加密维保频次等，有效压减非计划停机时长，进一步巩固了注水系统运行的保障能力。

The technical personnel of Jidong Oilfield conducted a comprehensive and detailed investigation of each well, covering aspects such as reservoir characteristics, wellbore conditions, and surface equipment. They formulated differentiated countermeasures to ensure that water wells could be effectively supported and stabilized. At the same time, they optimized the production operation mechanism, strictly standardized the approval process for opening and closing wells, and accelerated the resumption of production for winter shut-down wells. Regarding the potential water injection fluctuations caused by the operation of the measure wells, the technical personnel predicted and sorted out the workload two to three months in advance, scientifically coordinated the timing of well shutdowns, and increased the water injection rate by 0.7 percentage points, ensuring the all-day operation of the entire water injection system with a stable "base". On this basis, by implementing the subcontracting responsibility system for water injection equipment and increasing the maintenance frequency, they effectively reduced unplanned downtime and further strengthened the guarantee capacity of the water injection system operation.

针对南堡作业区第二采油管理中心采出水处理站设备老化等难题，冀东油田技术人员通过机械清洗速沉器、更换耐用核桃壳滤料、补充金刚砂过滤罐滤料、完成大型储罐清淤等一系列升级举措，完善多层级过滤净化工艺，让地下油层用上达标的“放心水”。

In response to the problems such as aging equipment at the Second Oil Production Management Center of the Nanbu Operating Area of Jidong Oilfield, the technical staff of Jidong Oilfield took a series of upgrading measures, including mechanical cleaning of the rapid sedimentation tank, replacement of durable walnut shell filter media, replenishment of diamond sand filter tank filter media, and completion of large storage tank dredging. They improved the multi-level filtration and purification process, enabling the underground oil layer to use up to standard "reliable water".

在确保注水量充足、注水水质达标的基础上，冀东油田技术人员依托岩芯数据、生产动态曲线，建立渗透率与吸水能力对应图谱，为每一口井、每一个小层精准地“开处方”。针对层间的开发矛盾，技术人员依据储层物性与启动压力差异，反复优化卡封深度，精准调控高低渗层注水量，实现均衡补能。

On the basis of ensuring sufficient injection water volume and meeting the quality standards of the injected water, the technicians of Jidong Oilfield relied on core data and production dynamic curves to establish a correlation map between permeability and water absorption capacity, providing precise "prescriptions" for each well and each small layer. In response to the development contradictions between layers, the technicians, based on the differences in reservoir properties and startup pressure, repeatedly optimized the sealing depth, precisely controlled the injection water volume of high and low permeability layers, and achieved balanced energy replenishment.

通过逐一会诊治理欠注井，冀东油田南堡作业区的分注层段合格率提升8.9个百分点。同时，优化洗井标准化作业模式，融合动态监测、管线冲洗、故障处置三项举措，严格落实洗井“三个结合”工作机制，规范单井洗井方案编制、过程跟踪及启动压力资料录取，推行平衡洗井标准化作业，全面提升了洗井质量与作业效率。

By conducting individual well diagnosis and treatment for under-injected wells, the qualified rate of the injection layer segments in the Nanbao operation area of Jidong Oilfield increased by 8.9 percentage points. At the same time, the standardized operation mode for well flushing was optimized, integrating three measures: dynamic monitoring, pipeline flushing, and fault handling. The "three-in-one" working mechanism for well flushing was strictly implemented, and the formulation, process tracking, and pressure data collection of single-well well flushing plans were standardized. Balanced well flushing standard operations were promoted, which comprehensively improved the quality and efficiency of well flushing.
