Abstract

The article deals with the development of the Karachaganak field using gas reinjection, to maintain reservoir pressure above the pressure of condensate formation, in the implementation of this process, the main tool for influencing the reservoir is gas injection wells, so the state of the bottomhole zone is a very important factor that needs to be paid attention to and permeability in this part of the reservoir is of great importance. An analysis of the main technological indicators of field development shows that the development system being implemented is effective. In connection with the removal of restrictions on gas injection, at the moment, despite the decrease in reservoir pressure below the start of condensation, today it is planned to expand the injection zone and increase the maximum level of annual gas reinjection to 68.9% of gas production.

KEYWORDS: Karachaganak field, bottomhole formation zone, hydrocarbons, injection wells, gas re-injection, cycling process, gas injection wells, reservoir pressure.
