Abstract—In order to develop a low-permeability condensate gas reservoir named X in Jilin Oilfield efficiently, it is significant to study and optimize the hydraulic fracture parameters of development wells. This paper builds a compositional model by utilizing the PVTi module of Eclipse software considering the PVT experimental result in this regard. On this basis, the effect of hydraulic fracture parameters on productivity is analyzed by establishing the numerical model in the view of theoretical analysis. Finally, the optimal hydraulic fracture of target area are obtained with the established geology model. The following conclusions can be drawn from this study:(1) Hydraulic fracturing can enhance the productivity of condensate gas reservoir; (2) Fracture length plays a more critical role in increasing productivity than fracture conductivity; (3) For the low-permeability condensate gas reservoir named X in Jilin Oilfield, the optimal parameters of fractures are half length=280m, conductivity= 22μm2·cm.
