The practice of operating technological wells in deposits with low filtration characteristics of ores shows that over time there is a decrease in their productivity. This is due to the formation of colmatation due to the deposition of solutes in process solutions, swelling of clay minerals, and mechanical movement of particles of the ore-containing horizon. The aim of the study is to increase the efficiency of downhole uranium production by selecting special decolmating solutions and selecting rational parameters of the technology of influencing the near-filter zone of the formation of geotechnical wells, improving the filtration characteristics of the formation depending on the mineralogical composition and structure of sedimentary materials. The main method of research is the sampling of sedimentation from the productive horizon at the uranium deposits of the Shu-Sarysu and Syrdarya depressions. Quantitative and qualitative characteristics and features of mineral compositions were determined by the X-ray phase method. A technique was developed and laboratory experiments were performed on the processing of sedimentation samples by the drip method using selected decolmating solutions.
