English. In a course of the research there were studied water wells of new design which were equipped with pipe regeneration systems and backfilled with clay sand. The research was realized in the conditions of the Republic of Belarus. The wells were drilled at the water intake ‘Felitsianovo’ in Minsk in 2015. The strength of the circulation pipes of wells regeneration system underground pressure was calculated for the worst case on the example of the well number 3. Water absorbing ability of pipes was tested during natural hydraulic experiment both results of this experiment and technological recommendations for wells repair were presented.

Скважины были пробурены на водозаборе ‘Фелицианово’ г. Минска в 2015 году. Выполнен расчет прочности циркуляционных трубок затрубных систем регенерации скважин на примере скважины № 31 от воздействия давления грунта при самом неблагоприятном случае эксплуатации скважины. Приведены результаты натурных гидравлических испытаний водопоглощающей способности трубок и рекомендации по технологии выполнения капитального ремонта скважин.
