    摘要: A method for calibrating fracture networks. The method includes estimating an average fracture width of a fracture network using one or more of net fracturing pressure, Poisson's ratio, shear modulus, and fracture height; determining microseismic event envelope and base intensity data using a three-dimensional geomodel including microseismic event data; and determining hydraulic fracturing treatment (HFT) fracture intensity of post-hydraulic fracturing treatment (post-HFT) based on the average fracture width and HFT volume data. The method further includes calibrating the base intensity data to the HFT fracture intensity to obtain calibrated HFT fracture intensity, determining a proppant transportation and distribution scenario, and generating a dual porosity reservoir model based on the calibrated HFT fracture intensity and the proppant transportation and distribution scenario.
