The article pays attention to the fact that biopolymer drilling solutions without a solid phase acquire viscoelastic properties in a porous medium that are not fixed by means of standard drilling rheometry. Filtration and micro-rheological (pore scale) studies have established that the depth of penetration of the filtrate and the screening of the bottomhole zone in this case are determined by the degree of structural-mechanical colmatation resulting from the contact interaction of the liquid and rock null.
