Technologies of processing of the precious zone with acid compositions

Abstract

Due to the fact that the majority of fields are at the final stage of development, special attention is paid to the methods of intensification of well inflow in order to clean the overburden zone and increase the capacity and productivity of wells. The most effective, common and cost-effective method is acid treatment of the near-outlet zone of the formation. The purpose of SKO is to thoroughly clean porous or cavernous and fissured channels that filter, improve or restore a certain value of permeability in the most problematic zone near the well.
