Key words:<\/strong> development of wells, abnormally low formation pressures, bottomhole formation zone, clay-sand plugs, colmatant, acid solution, foam composition, reservoir cleaning, solvent capacity.

The article presents the results of testing compositions for development of wells under abnormally low formation pressures. Methods for washing clay-sand plugs and cleaning the bottom of the well from the products of bottomhole formation zone destruction, remnants of drilling fluids and mechanical impurities using process liquids which possess the necessary physicochemical properties when applied under abnormally low formation pressures are considered.\nCompositions of special fluids for well development and stimulation of formation fluids inflow, technology of bottomhole formation zone treatment with clay acid solutions and foaming liquids are proposed.<\/p>\n
