Quantitative design method for multi-cluster fracturing non-uniform perforation of horizontal well

The invention discloses a quantitative design method for multi-cluster fracturing non-uniform perforation of a horizontal well, and belongs to the technical field of oil-gas field development, and the quantitative design method for the multi-cluster fracturing non-uniform perforation of the horizontal well comprises the following steps: obtaining well bore parameters of a fractured well, fracturing well completion information, reservoir geological parameters and fracturing construction parameters; according to the fractured well shaft parameters, the fractured well completion information, the reservoir geological parameters and the fractured construction parameters, determining the magnitude of stress interference between fractures near all fractures, and forming a dimensionless parameter lambda according to the magnitude of stress interference between fractures near all fractures; under the condition that section internal stress heterogeneity is not considered, a first perforation parameter is selected, and
