Abstract

The presence of matrix oil at a concentration below the filtration threshold in the deposits of large gas-condensate fields and in the gas part of oil and gas-condensate fields necessitates the search for new ways to increase component recovery. The research was carried out within the framework of works on hydrodynamic substantiation of the technology of extraction of matrix oil and retrograde condensate from gas-saturated source deposits at late stages of development. In the paper, on the basis of a test multicomponent model using key parameters of the Vuktyl oil and gas-condensate field, a rational variant of application of the technology for increasing component recovery is selected, including not only the volume and rate of fluid injection, but also the design of wells.
