Abstract

Severe slugging is a prevalent issue in offshore oil wells that significantly hampers oil production. While active pressure control has proven effective in mitigating this problem, determining optimal setpoints remains a manual and labor-intensive procedure. This study introduces the Input-Output Cross Autocorrelation Diagram (IO-CAD), which examines both input and output autocorrelations to provide a more comprehensive assessment of control loops compared to previous methods that only use output autocorrelation data. Four indicators based on IO-CAD were developed and tested in two case studies involving offshore oil production. They were compared to an oscillation detection method published in the literature, as oscillations in the control loop may indicate the slugging flow. Early detection of slugging patterns is crucial in offshore oil production to prevent severe slugging and stabilize control loops. The results demonstrated that the IO-CAD indicators are robust against setpoint changes, disturbances, and noise in the control loop performance assessment, while the oscillation detection method from the literature is sensitive to measurement and process noise, as well as control loop oscillations.
用于海上石油生产控制回路性能评价的输入-输出交叉自相关图(IO-CAD)
严重的段塞流是海上油井普遍存在的问题,严重影响了石油生产。虽然主动压力控制已被证明可以有效缓解这一问题,但确定最佳设定值仍然是一个人工和劳动密集型的过程。本研究介绍了输入-输出交叉自相关图(IO-CAD),它检查了输入和输出自相关,与以前只使用输出自相关数据的方法相比,提供了更全面的控制回路评估。开发了基于IO-CAD的四个指标,并在涉及海上石油生产的两个案例研究中进行了测试。它们与文献中发表的振荡检测方法进行了比较,因为控制回路中的振荡可能表明段塞流。在海上石油生产中,早期发现段塞流模式对于防止严重段塞流和稳定控制回路至关重要。结果表明,IO-CAD指标对控制回路性能评估中的设定值变化、干扰和噪声具有鲁棒性,而文献中的振荡检测方法对测量和过程噪声以及控制回路振荡敏感。

期刊介绍: This international journal covers the application of control theory, operations research, computer science and engineering principles to the solution of process control problems. In addition to the traditional chemical processing and manufacturing applications, the scope of process control problems involves a wide range of applications that includes energy processes, nano-technology, systems biology, bio-medical engineering, pharmaceutical processing technology, energy storage and conversion, smart grid, and data analytics among others. Papers on the theory in these areas will also be accepted provided the theoretical contribution is aimed at the application and the development of process control techniques. Topics covered include: • Control applications• Process monitoring• Plant-wide control• Process control systems• Control techniques and algorithms• Process modelling and simulation• Design methods Advanced design methods exclude well established and widely studied traditional design techniques such as PID tuning and its many variants. Applications in fields such as control of automotive engines, machinery and robotics are not deemed suitable unless a clear motivation for the relevance to process control is provided.
