Efficiency Analysis of Processing Injection Wells with Acid Compositions

Abstract:

Efficient development of oil reservoirs includes measures to restore and enhance the porosity and permeability properties of reservoir units that are gradually impaired during well operation. As a rule, various technologies of bottom-hole formation zone processing (BZP) of wells are used for these purposes. Special requirements to BZP technologies are applied during interventions in low-permeability reservoirs where the geological structure of reservoir units has the highest impact on the efficiency of works. In this relation, it seems interesting to study the specifics of geological structure of reservoir units in a laboratory for the efficiency of interventions using physical and chemical methods of reservoir stimulation. The research objective is to assess the efficiency of processing reservoir units with acid compositions of various concentration and type. Using laboratory experiments, physical and chemical parameters were quantitatively assessed that characterize the speed and depth of interaction between acid compositions and reservoir units.
