摘要： The present disclosure provides a method and apparatus for partitioning a reservoir temperature field, a computer device, and a medium. The method for partitioning the reservoir temperature field includes: carrying out discretization on a spatial region of a reservoir to obtain a first number of reservoir region spatial discrete points; based on water temperature-hydrodynamic features of each reservoir region spatial discrete point at different moments and an actual spatial position of each reservoir region spatial discrete point, carrying out clustering processing on the first number of reservoir region spatial discrete points to obtain a second number of reservoir temperature field regions and a spatial distribution of each reservoir temperature field region; and according to a corresponding actual spatial position of each reservoir temperature field region, determining a region type corresponding to each reservoir temperature field region. According to the present disclosure, an obtained reservoir temperature field partitioning result does not need to be depended on experimental parameters, reservoir temperature field partitioning based on a specified time interval has higher objectivity and stability, and the powerful technical support can be provided for actual operation and scheduling of the reservoir.
