  • Descrição: Based on the results of physical modeling of the effect of the applied jamming fluids on the filtration-capacitance properties of rock samples in a water-saturated porous medium, it is shown that the recovery coefficient of the core sample of the development object after filtering the jamming fluid of some core samples was less than 90%. Based on analytical calculations by the method of J.E. Oddo and M.B. Thomson's analysis of the mixing processes used in the process of silencing waters on the compatibility and degree of salt deposition revealed that when mixing reservoir water and water of the silencing fluid under reservoir conditions at T = 30 °C and P = 7 MРa, the precipitation of non-organic salts of calcite CaCO3 with a sediment mass in the range of 0.39-0.77 g is predicted/l and CaSO4 anhydrite – 0.01-0.03 g/l. Experimental studies on the hydrodynamic modeling of the process of pumping silencing fluids based on potassium chloride and determining the degree of change in filtration characteristics have shown an increase in the coefficient of recovery of acceptance. Keywords: silencing fluid; filtration experiment; modeling; permeability coefficient; calcite salt deposition; reservoir water compatibility.
