Most of the literature on short-term production optimization concerns the computation of optimal system settings for steady-state operations. Such methodologies are applicable when the scales of time are faster than reservoir dynamics, and slower than the dynamics of top-side equipment. Effectively static problems are solved over time in response to changes in the prevailing conditions, which will remain persistent for long periods. However, when platform conditions change frequently or suddenly possibly due to reduced processing capacity, the dynamics of wells should not be neglected and well operations should be scheduled over time. To this end, this paper proposes a novel mathematical formulation for production optimization when dynamics matters, specifically when wells are shut-in (due to processing capacity drops) and restarted later as the normal conditions are recovered. The effectiveness of the methodology to schedule well operations is assessed by simulation of synthetic and field cases involving an offshore production platform.

关于短期生产优化的大多数文献都涉及稳态操作的最佳系统设置的计算。当时间尺度比油藏动力学快，而速度比顶侧设备动力学慢时，则可应用此类方法。随着时间的流逝，有效的静态问题将随着时间的变化而得到解决，这种变化将持续存在很长时间。但是，当平台条件频繁变化或突然由于处理能力降低而突然变化时，不应忽略油井的动态变化，应随时间安排油井的作业时间。为此，本文提出了一种在动力学很重要时用于生产优化的新颖数学公式，特别是在关闭井（由于处理能力下降）并随后在恢复正常条件之后重新启动时。通过模拟涉及海上生产平台的综合案例和现场案例，评估了计划井作业的方法的有效性。
