PROGRESSIVE TECHNOLOGIES FOR INCREASING CONDENSATE RECOVERY FROM GAS-CONDENSATE FIELDS IN THE CYCLING PROCESS WITH THE USE OF PROGRAMMING METHODS

The object of research is the technology of developing gas-condensate fields with a high condensate content when introducing reservoir pressure maintenance systems. Gas- condensate fields can be developed both in natural modes. and in reservoir pressure maintenance modes. The experience of developing the Timofievsky and Kotelevsky fields in the cycling process mode showed an increase in condensate recovery from deposits by 16 and 6% compared to depletion. It is proposed in the projects of development of gas condensate fields with a high content of condensate to consider the option of development in the cycling process mode with a general coverage coefficient in terms of area, section and structure of the pore space. When designing the development of gas condensate fields in the cycling process mode, taking into account the pore space coverage coefficient by displacement will allow to specify the volumes of dry gas injection into the formation; to determine the type of cycling process - full, partial, stepwise or mixed; to determine the development period in the cycling process mode and the time of transition to depletion; to specify the condensate recovery coefficient. Thus, the assessment of the coverage coefficient by displacement of raw gas by dry section area and in the microstructure of the pore environment is a problematic issue, the solution of which significantly depends on the optimization of the development of gas condensate deposits in the cycling process mode with minimal capital costs.
