The phase characteristics change of condensate gas
reservoirs is an important difference from conventional gas
reservoirs , but now the effects on dynamic production of
condensates gas reservoir is neglected. This paper considers the
condensates gas reservoir as the mixture of each hydrocarbon kind
of chemical compounds , then establishes flow equations of ith
component and total hydrocarbon , and prediction method of
production performance of condensate gas reservoirs by combining
phase balance equation , thermal equilibrium equation and
material conversation principle , initial condition and constant
pressure boundary condition , and applying IMPES numerical
simulation method. Lastly , production rate of condensate fluid
and natural gas were analysed , and effects of hydrocarbon
components on production performance. It was shown that the
dynamic production performance have been obviously influenced
by hydrocarbon components whether the formation was
hydraulically fractured.
