Multi-layer oil reservoir development characteristic evaluation method, system, equipment and medium

The invention relates to a multi-layer oil reservoir development characteristic evaluation method, system, equipment and medium, and the method comprises the steps: taking a well group composed of a central oil producing well and n injection wells around the central oil producing well as a research object, and obtaining various physical property production data of the research object; determining a seepage resistance formula between the injection wells and the production wells on the basis of the obtained various physical property production data, and drawing a saturation-seepage resistance chart; calculating corresponding seepage resistance and drawing a single-layer pressure-flow relation chart based on the water saturation under the limit water content condition and the initial oil content condition; and on the basis of the obtained real-time wellhead pressure of each layer of oil reservoir, the obtained liquid production profile data at the specific moment, the single-layer pressure-flow relation chart an
