“…The initial gas permeability of artificial samples was approximately the same (3.6-3.7 m). To determine the clogging ability of each filler, a control solution of bentonite was prepared, and to compare the clogging ability of fillers, the same amount (0.5%) of fillers was added to the initial solution [6,7]. The studies of the bridging ability of fillers were carried out on a laboratory setup shown in Figure 1.…”

“…Considering the above, we have studied the bridging ability of a number of widely used fillers in the conditions of Uzbekistan. For example, hydrolyzed cotton cellulose (HC), diacetylcellulose (DAC), triacetylcellulose (TAC), asbestos, kostra-kenaf, marble powder, as well as a powdered mass layer -WC-Y736-A polyethylene produced by the Shurtan gas chemical plant, Uzbekistan [7].…”

The insufficient density and low strength of the mudcake does not ensure the complete cessation of drilling fluid penetration into the reservoir capillary volume. At the same time, the penetrating components of the solutions, upon contact with the formation components, lead to clogging of the capillary volume due to physicochemical processes. The experiments were carried out on cores made from carbonate rocks of a similar composition of the productive formation and on artificial cores made from carbonate rocks, 30 mm in diameter and 40 mm long. The initial gas permeability of artificial samples was approximately the same (3.6-3.7 m) According to the results, the high strength of the colmatation barrier created by WC-Y736-A polyethylene powder and the low strength of the bonfire-kenaf and cotton cellulose. The resulting deep clogging of the pores and sufficient strength of the polyethylene colmatation barrier was achieved due to their high degree of swelling and physico-chemical effect of the colmatant with the rock.

One of the ways to improve the environmental situation in various regions of the world has become the improvement of technologies for protection against hazardous pollution in soil, atmosphere, groundwater. The article is devoted to the analysis of the conceptual proposal within the framework of participation in the competition “Students reinventing cities. The promising methods of elimination and localization of environmental pollution using geochemical barriers are outlined. Examples of natural and artificial geochemical barriers are considered. Attention is drawn to the possibility of using anti-filtration screens as artificial barriers in areas with passive technogenic impact. The potential of using artificial barriers for the safe cultivation of plant crops at the former Payatas controlled waste disposal facility in Quezon City, Philippines is being identified. The importance of creating green spaces in the territory with limited opportunities for economic use is justified.
