Annotation:

The article presents the results of laboratory studies on the impact of complexones on the restoration of the permeability of the near-bottomhole formation zone (BFZ) in order to increase the productivity of wells in fields and underground gas storages (UGS). The use of process fluids based on complexones during BFZ treatments allows obtaining an economic effect in the oil and gas industry due to the restoration of porosity and permeability properties (PPP) of productive horizons and the low cost of the proposed compositions.
