Annotation:

The article considers the processes leading to colmatation of anti-sand filters and decrease of production wells flow-rates in gas fields and underground gas storages (UGS). In order to destroy colmatation formations and restore wells flow-rates, a composition of a process fluid based on a phosphorus-containing complexon is proposed. The use of the developed process fluid composition will allow restoring the production wells flow-rates due to the regeneration of anti-sand filters as well as increasing the overhaul period.
