An Algorithm to Determine the Truncated Weibull Parameters for Distribution of Throats and Pores in Random Network Models

In random network models, sizes for pores and throats are distributed according to a truncated Weibull distribution. As result, parameters defining the shape of distribution critical characteristic network. this paper, an algorithm distribute in was established more representatively describe topology porous media. First, relations between dimensionless throat were studied series standard curves obtained. Then, by analyzing capillary pressure curve core sample, frequency histogram All transformed numbers ranged from 0 1. Curves compared curves, could be determined inverse algorithm. Finally, aspect ratio average length adjusted simultaneously fit porosity whole established. The predicted relative permeability good agreement with experimental data cores, indicating validity
