The invention relates to the technical field of oil production engineering, in particular to a vertical well multi-branch-seam fracturing site construction judgment method. The method mainly solves the problem that an existing method cannot systematically, effectively, quantitatively and accurately judge whether the vertical well multi-branch-seam fracturing site produces branch seams or not. According to basic construction parameters of a well A and bottom hole pressure gauge data, an on-way friction resistance board and a liquid column pressure board are established, net pressure in a well Bseam is calculated in real time in combination with the basic construction parameters of a well B, and an evaluation parameter and a judgment method corresponding to whether branch seams are generated in a fracturing site of the well B or not are given. The method has the advantages of being capable of accurately, objectively and effectively judging whether the vertical well multi-branch-seam fracturing site generates the branch seams or not and the like.
