Water for oil pump stations and compressor stations of the main hydrocarbon carriers transmission systems, as well as for most other production facilities of the oil and gas complex is usually supplied from the underground sources. In this case, the function of water intake structures is performed by the bored wells or special wells. As most of them are located in quick ground, they require the use of filters of various designs. In the process of water supply systems operation, wells filters and pre-filter zones of aquifers are contaminated with mechanical particles as well as with the depositions of calcium salt, magnesium salt, silicon salt and other elements dissolved in under-ground waters. It inevitably leads to the increase in hydraulic resistance and, accordingly, to the decrease in wa-ter flow and water intakes productivity. The construction of new buildings requires additional substantial capital investments; therefore it is considered to be economically impracticable and is used very rarely. The more rational way to restore the well flow rate is to clean the filters and the aquifers pre-filter zones off the clogging. It gives a possibility to get a significant economic effect. The analysis of the existing methods and means of water supply wells recovery shows that despite the urgent need to improve water supply and to use groundwater rationally, the search for the most effective methods of regeneration of water take systems is still ongoing. Nowadays, the devel-opment of treatment modes for filters and the prefilter zone of aquifers implies the use of approaches that summa-rize the experience of previous methods which need further theoretical and experimental justification. The authors offer a more effective method for the destruction and dispergation of colmatation deposits. It requires the creation of the vibrational impact inside the filter as well as the creation of a powerful filtration flow of alternating direc-tion by implementing a multi-regulated explosion of the steam-and-gas mixture. It gives an opportunity to use it under a wide range of hydrogeological conditions, as well as in the wells equipped with filters of different types. The suggested method is simple and cost-efficient. In order to find scientifically substantiated criteria for the se-lection of optimal modes of wells treatment using this method, the authors have made a series of research. One of the main purposes of the studies is to determine the nature of the distribution and the parameters of elastic hydro-dynamic oscillations in the aquifer which are caused by the explosion of steam-and-gas mixture in the filter area of the water supply well.
