Abstract
The paper presents the timeframe of the under-stream period of hydrogeological well operation. The causes of the hydrological wells flowrate reducing while long operation have been indicated. The methods of the hydrological wells and near-filters zone decolmatation have been described. The pulse-reagent well recovery has been shown to be the most widely used method. The filter colmatant composition has been given and the possible filter failure cause has been shown. Laboratory investigations have been done with a special equipment that can be seen on the drawing. A solution of sulfamic and triacetate acid, corrosion inhibitor, surfactant, sodium tripolyphosphate, adalic acid and water has been suggested as an invention. Using of these chemicals allowed to achieve the synergistic effect. A double swab-packer and a washing device for wells regeneration has been designed, its description and drawing have been given. The optimal time for the colmated filter regeneration has been indicated. Laboratory investigations results are given in the table. The chemic equipment used for chemicals transportation and keeping of the reagents has been described. The created solution for hydrogeological wells regeneration has been shown to be the optinal and its using efficiency is forty percent more than that of the known one. The created solution is recommended for hydrogeological wells regeneration in field works.
