Abstract
The application discloses a method and device for making a physical fault model and empirically evaluating its sealing performance. The method comprises S1 preparing a fault filling zone model; S2 testing the initial permeability of the fault filling zone model before sealing it with nano-microsphere infused slurry; S3 placing the fault filling zone model into reservoir rocks, drilling slurry injection wellbores in the reservoir rocks on both sides of the fault filling zone model, and creating a perforation section near the bottom of the slurry injection wellbore directed towards the fault filling zone model; subsequently, injecting nano-microsphere infused slurry into the slurry injection wellbore to perform a sealing experiment; S4 taking out the fault filling zone model after the slurrying process in S3 and repeating S2 to test the permeability of the model after sealing; and S5 calculating the sealing performance index of the fault filling zone model.
