Improvement of Hydraulic Facing Technology by Modeling Permeability Formed Cracks for Specific Mining and Geologi-cal Conditions

Abstract

The article describes the improvement of hydraulic fracturing technology by modeling the permeability of the formed fractures for specific mining and geological conditions. The description of the main indicators of the properties of the propping material for hydraulic fracturing is given. To prevent undesirable consequences when using various proppants in a number of Russian fields, testing was carried out for the proppant compliance with the ANI RP-56 standard, the results of which are shown in the article. Shown that it can be seen that the type of proppant and its physicochemical characteristics significantly affect the permeability of the hydraulic fracture. Therefore, only after conducting studies to assess the permeability in conditions close to reservoir conditions in the well, it is possible to select the type of proppant for hydraulic fracturing, potentially the most effective for specific mining and geological conditions. Concluded that the correct choice of proppant material for hydraulic fracturing minimizes the percentage of the probability of fracture of the proppant grains in the hydraulic fracture, as well as the removal of proppant grains into the wellbore, which ultimately has a positive effect on the well operation during development and operation in design mode.
