几十年来,人工举升优化严重依赖于人工干预、定期试井以及经验丰富的工程师的判断。电潜泵 (ESP)、气举和游梁泵(三种最广泛使用的举升系统)各自都面临着各自的优化挑战,例如平衡设定点、管理压缩机约束以及解读测功图。这些流程虽然有效,但历来耗时耗力、反应迟钝,并且难以在大型油井中推广。

机器学习 (ML) 和自动化技术的加速部署正在改变这一格局。通过将智能嵌入控制回路,操作员现在可以从被动决策转变为主动持续优化。曾经由单个工程师手动完成的任务,如今越来越多地由自主系统完成,这些系统能够从数据中学习、实时调整,并轻松扩展到数百或数千口油井。

最近的案例研究说明了这种转变如何在不同的举升类型中展开,每个案例研究都表明人工举升的自主时代不再是理想,而已成为现实。

如论文 SPE 219528 所示,在二叠纪盆地的 ESP 数据集上训练的神经网络模型现在可以推荐并直接写入最佳泵设定点。该部署实现了 2-4% 的石油提升和更长的运行寿命,同时展示了完全的自泵能力,即泵在极少的人为监督下运行。

在气举领域,埃克森美孚大规模推广的闭环优化工作流程也同样卓有成效。正如论文 SPE 219553 所详述,目前已有超过 1,300 口油井由自动化系统管理,该系统可进行多速率测试、更新井下压力模型,并对未安装压力表的油井应用机器学习 (ML)。其结果是:产量持续提升约 2%,且几乎不增加运营或资本支出。

在游梁泵方面,测力计图表的手动解读正在被实时机器学习分类所取代。在论文 SPE 224979 中,研究人员使用 XGBoost 和卷积神经网络等模型分析了超过 70 万份测力计图表,分类准确率约为 95%。通过与 OSIsoft AF 和基于异常的监控功能集成,该解决方案可提供预测分析和主动警报,从而减少停机时间并延长设备寿命。

比较这三种方法,可以发现一些明显的区别。在ESP优化(SPE 219528)中,操作员依靠神经网络推荐并自主调整设定点,实现了200多口井的产量提升。气举优化(SPE 219553)采用了更广泛的油田方法,将闭环工作流程扩展到1300多口井,其中多速率测试和机器学习模型持续更新注入速率,以最小的增量成本实现产量提升。与此同时,游梁泵优化(SPE 224979)较少关注直接产量提升,而更多地关注可靠性和预测性监控,其中机器学习模型可以实现主动维护并减少停机时间。

尽管存在差异,这三个举措却有着共同之处:每个系统都从手动、工程师驱动的调整转向自动化和自主优化;每个系统都利用机器学习与现有现场基础设施相结合;并且每个举措都证明,即使是每口井的适度改进,当扩展到数百或数千口井时,也会转化为整个油田的巨大收益。

这些案例研究涵盖了ESP、气举和游梁泵,展现出一种统一的转变:机器学习正在将人工举升重新定义为一个自我优化、持续学习的系统。2.4%的产量提升,如果在各个油田推广,将转化为可观的增量产量。随着系统学会在最佳范围内运行,设备的使用寿命得到提升,而工程师们也从重复的监控中解放出来,专注于更高价值的分析。

这里所描述的进步不仅仅是一些单独的技术改进,更是上游作业领域更广泛数字化转型的标志。人工举升长期以来一直是手动调整和工程师直觉的领域,如今正成为自动化的试验场。

通过将人工智能嵌入到生产系统的核心,运营商不仅可以优化单个油井,还可以构建未来数字油田的基础,在未来的数字油田中,决策由数据驱动,工作流程自主,工程师将他们的专业知识集中在复杂的挑战上,而不是常规的调整上。

Artificial lift

Artificial Lift-2025

The accelerating deployment of machine learning and automation is changing the artificial lift landscape. By embedding intelligence into the control loop, operators now can move from reactive decision-making to proactive, continuous optimization.

JPT_2025-10_ALFocus.jpg

For decades, artificial lift optimization has relied heavily on manual intervention, periodic well tests, and the judgment of experienced engineers. Electric submersible pumps (ESPs), gas lift, and beam pumps (the three most widely used lift systems) each have presented their own optimization challenges, such as balancing set points, managing compressor constraints, and interpreting dynamometer cards. These processes, while effective, have historically been time-intensive, reactive, and difficult to scale across large well inventories.

The accelerating deployment of machine learning (ML) and automation is changing this landscape. By embedding intelligence into the control loop, operators now can move from reactive decision-making to proactive, continuous optimization. What was once a manual task handled by individual engineers is increasingly performed by autonomous systems that learn from data, adjust in real time, and scale effortlessly across hundreds or thousands of wells.

Recent case studies illustrate how this transformation is unfolding across different lift types, each demonstrating that the age of autonomy in artificial lift is no longer aspirational but is now an operational reality.

Neural-network models trained on ESP data sets in the Permian Basin now recommend and directly write optimal pump set points, as shown in paper SPE 219528. The deployment delivered a 2–4% oil uplift and longer run life, while demonstrating full self-pumping capability, where pumps operate with minimal human oversight.

In gas lift, ExxonMobil’s large-scale rollout of a closed-loop optimization workflow has been equally impactful. As detailed in paper SPE 219553, more than 1,300 wells are now managed by an automated system that runs multirate tests, updates downhole pressure models, and applies ML for wells without gauges. The outcome: a consistent approximately 2% production uplift, achieved with little incremental operational or capital expenditure.

On the beam-pump side, manual interpretation of dynamometer cards is being replaced by real-time ML classification. In paper SPE 224979, more than 700,000 dynacards were analyzed with models such as XGBoost and convolutional neural networks, achieving approximately 95% classification accuracy. By integrating with OSIsoft AF and exception-based surveillance, the solution provides predictive analytics and proactive alerts, reducing downtime and extending equipment life.

When comparing the three approaches, some clear distinctions emerge. In ESP optimization (SPE 219528), operators relied on neural networks to recommend and autonomously adjust set points, achieving production uplift across more than 200 wells. Gas lift optimization (SPE 219553) took a broader fieldwide approach, scaling a closed-loop workflow to more than 1,300 wells, where multirate testing and ML models continuously updated injection rates, delivering uplift at minimal incremental cost. Meanwhile, beam-pump optimization (SPE 224979) focused less on direct production uplift and more on reliability and predictive surveillance, where ML models enabled proactive maintenance and reduced downtime.

Despite their differences, the three initiatives share commonalities: Each system moved from manual, engineer-driven adjustments to automated and autonomous optimization; each leveraged ML in combination with existing field infrastructure; and each demonstrated that even modest per-well improvements, when scaled across hundreds or thousands of wells, translate into substantial fieldwide gains.

Across ESPs, gas lift, and beam pumps, these case studies demonstrate a unifying shift: ML is redefining artificial lift as a self-optimizing, continuously learning system. Production uplifts of 2–4%, when multiplied across fields, translate into substantial incremental barrels. Equipment longevity improves as systems learn to operate within optimal ranges, while engineers are freed from repetitive monitoring to focus on higher-value analysis.

The advances described here are more than isolated technical improvements; they are signposts of a broader digital transformation across upstream operations. Artificial lift, long the domain of manual adjustments and engineer intuition, is now becoming a proving ground for autonomy.

By embedding AI into the very core of production systems, operators are not just optimizing individual wells; they are building the foundation of the digital oilfield of the future, where decisions are data-driven, workflows are autonomous, and engineers focus their expertise on complex challenges rather than routine tuning.
