    • Abstract
  • The hydraulic fracture computation model applicable to the conventional reservoir was revised and the one fit for the highly developed coal reservoir's calculation of the fracturing slit's delivery capacity was determined based on the highly developed coal reservoir's geological model in Qinshui basin.By the analysis of the fracturing technologies, parameters and coal reservoir's mechanical characteristics, corresponding calculations combined with the sand's subsiding theory in Newton fluid were programmed using numerical simulations.The factors were analyzed and the results' reliability was evaluated.The results indicate that the sand's distribution is parted in different areas which have different delivery capacities.The delivery capacity obtains higher value under smaller silt's length and width, evener sand distribution and higher sand weight.It has important significance to evaluate the construction's applicability and optimize fracturing parameters in order to get the best delivery capacity.
