The calibrated microscale properties (Tables 1 and 2 are used as input parameters in the model shown in Figure 2.Numerical modeling of fracture closing and ,fracturing fluid flowback, is then calculated. Figures 9 and 10 plot the profiles of a proppant pillar at two different closing stresses, 20.7 MPa and 41.4 MPa, respectively. The height of the proppant pillar is 6 mm, and the diameter is 10 mm.

Based on the experimental and field data, ,fracturing fluid flowback, rates and gas production rates of 9 wells were analyzed. It is indicated that the same block follows an overall trend, namely, the lower the ,flowback, rates, the more developed the micro fractures, the better the volume stimulation effect and the higher the gas production rates.
