The supramolecular catalytic system on the basis of metal and organic clusters, that can be transported into the bed in the hydrophobic cavity of the macrocyclic receptor has been developed and created in the work.
The experimental investigations were conducted for test of the developed nanostructure capability to change the porous medium permeability, both with the aim of water inflows shut-off and effectiveness increase of the oil recovery from the porous medium. The solution with nanostructure concentration of 0.5, 1, 2, 3 % in the fresh water was used. The conducted experiments showed that with nanostructure concentration increase in the solution the porous medium permeability after its processing by nanostructure decreases for all investigated permeabilities. Nanostructure concentration increase in solution and decrease of the initial porous medium permeability leads to residual resistance factor growth and accordingly to its transmissibility decrease. It was determined that the developed system is an effective means for regulation of the porous medium water permeability.
