Abstract

The article is devoted to the methods of extracting reserves from complex carbonate reservoirs based on a complex of geological and technical measures. The parameters influencing the technological efficiency and the increase in oil production are analyzed. These include geological and filtration-capacitive heterogeneity, as well as technological parameters. The division of carbonate rocks into petrotypes is considered in order to assess their impact on input technological indicators – water content, oil flow rate. Geological conditions have been studied, as well as geological and technical parameters that have a significant impact on oil production and reservoir flooding during the multistage acid fracturing. The studied relationships allow for a detailed analysis of the success of events and a detailed approach to the selection of candidate wells.
