REDUCING RESERVOIR PERMEABILITY IN WELLBORE ZONE IN INTERACTION OF INJECTED AND RESERVOIR FLUIDS

The analysis of the problem of reducing the permeability of the reservoir wellbore zone during hydraulic fracturing as a result of interaction between carrier of proppant (gel), formation fluids (formation water and hydrocarbons) and mechanical impurities was conducted, the solutions of this problem were presented. The methodical and technological solutions for the well bottomhole treatment with solutions of special compositions (reagents) were given, which with sufficient efficiency contribute to the restoration of the fracture crack permeability. The proposed methodical approach is recommended to use before the massive use of well treatment technologies in order to increase their productivity.
