Comprehensive evaluation method for laying effect of proppant in fracturing crack

The invention discloses a comprehensive evaluation method for the laying effect of a proppant in a fracturing crack. The method comprises the following steps: simulating the laying form of the proppant under different experimental parameters through a flat plate slit sand conveying device, and obtaining the evaluation parameters of the laying effect of the proppant; establishing a hierarchical structure model and a judgment matrix A (I); introducing a transfer matrix D to obtain a consistency optimization judgment matrix A (II); calculating a weight vector omega and carrying out consistency check; establishing a factor set U and an evaluation set V; establishing a paving effect evaluation fuzzy matrix A (III); and establishing a comprehensive evaluation model for the paving effect of the in-seam proppant, and comprehensively evaluating the paving effect of the in-seam proppant under the condition of a flat plate slit sand conveying experiment. The proppant laying effect comprehensive evaluation model is const
