中国石油（伊拉克）西古尔纳公司抢抓地层压力恢复关键窗口期，全面提升注水系统运行效率，强化油藏“蓄势补压”，为稳产上产蓄力赋能。

China National Petroleum (Iraq) West Qurunna Company seized the critical window period for restoring formation pressure, comprehensively enhanced the operational efficiency of the water injection system, strengthened the "pressure accumulation and pressure replenishment" of the reservoir, and provided support for maintaining stable production and increasing output.

针对低压区治理，公司多措并举，趁油井投产节奏放缓，快速投运2口高注入量注水井。同时，通过提高供水压力、增加注水压差，对5口吸水能力较弱的注水井实施治理，进一步提升了区域注水强度和压力补给能力。

Regarding the management of the low-pressure area, the company has taken multiple measures. Taking advantage of the slowdown in the production schedule of oil wells, it quickly put into operation 2 high-injection-volume water injection wells. At the same time, by increasing the water supply pressure and enhancing the injection pressure difference, it implemented treatment for 5 water injection wells with relatively weak water absorption capacity, further enhancing the regional water injection intensity and pressure replenishment capacity.

公司巧用生产井措施实施进度放缓、修井机资源充裕的有利时机，筛选15口低效注水井开展高渗透易窜层封堵治理，筛选7口层内欠注井实施储层酸化改造。其中一口欠注井经改造后，层内吸水能力实现大幅提升。同时，开展水井欠注层加酸压裂先导试验，通过多种技术手段的综合应用，增强油藏整体注水效果。

The company took advantage of the favorable circumstances of the slow progress in production well measures implementation and the abundant resources of well repair machines. They selected 15 low-efficiency water injection wells to carry out high-permeability interbed leakage prevention treatment, and selected 7 wells with insufficient water injection within layers to implement reservoir acidification modification. One of the wells that underwent the modification saw a significant improvement in the water absorption capacity within the layer. At the same time, a pilot test of adding acid and fracturing for waterless injection layers was conducted. Through the comprehensive application of various technical means, the overall water injection effect of the reservoir was enhanced.

针对高压注水系统井筒结垢问题，公司在前期专项课题研究基础上，利用系统停运间隙，督促当地服务商加密井筒的垢样取样频次，深化结垢机理认识，优化升级清垢工艺流程。同时，筛选典型井开展清垢先导试验，验证优化方案的可行性与有效性，为提升注水系统运行效率夯实基础。

In response to the problem of wellbore scaling in the high-pressure water injection system, based on the previous specialized research project, the company, during the downtime of the system, urged the local service provider to increase the frequency of collecting scaling samples in the wellbore, deepen the understanding of the scaling mechanism, and optimize and upgrade the cleaning process flow. At the same time, typical wells were selected to conduct pilot cleaning tests to verify the feasibility and effectiveness of the optimized plan, laying a solid foundation for improving the operational efficiency of the water injection system.
