Rationale for the technological gas-condensate well operation conditions under the conditions low-permeability reservoir
The development of oil and gas condensate fields is accompanied by phase transformations of reservoir mixtures, i.e. the transition of condensate from the gas state at the formation pressure below the condensation start pressure and its reverse evaporation when the maximum condensation pressure passes. Dynamic condensation leads to a decrease in permeability in the bottomhole zone, as a result, the productivity of the well is reduced.We have used the method of gas-dynamics research at steady-state filtration conditions in our work in order to minimize the influence of retrograde processes and the justification of the technological well operation conditions of usage gasdynamics research at steady-state filtration conditions.Especially, set up a problem is important in conditions of low-permeability reservoirs with a significant potential content of condensate in the formation gas.
