Method and device for identifying water channeling channel of heavy oil reservoir

The invention relates to an identification method and device for a water channeling channel of a heavy oil reservoir, and belongs to the technical field of oil reservoir development. The method comprises the steps that the average formation pressure of a target interval and the lowest pressure center point of the target interval are obtained, and an area of a first set pressure range around the lowest pressure center point serves as a potential edge water invasion path D1; the water inlet rate of each production well in the target interval is obtained, and the area with the water inlet rate higher than a first set rate threshold value serves as a potential edge water invasion path D2; the stratum average permeability of the whole target interval and the permeability of all positions of the target interval are obtained, and a potential edge water invasion path D3 is determined; determining the water-phase flow velocity distribution of the target interval through numerical simulation, and taking an area with th
