Inter-injection and production well static streamline characterization method based on control balance point

The invention relates to the technical field of injection-production wells, in particular to an injection-production inter-well static streamline characterization method based on a control balance point, which comprises the following steps of: dividing a central water injection well control unit of an injection-production well network; a connecting line between the adjacent production wells and a connecting line between the adjacent production wells and the water injection well are determined, and the linear distance between the flow field control balance point and the production wells is calculated; obtaining the linear distance between the water injection well and the streamline control boundary point and the coordinate of the streamline control boundary point; the sum of the main flow line seepage capacity of the water injection well and the adjacent production well and the main flow line seepage capacity corresponding to all the small layers of the water injection well is calculated; calculating inter-wel
