Abstract: Non-Darcy flow is often called turbulent flow, and it may occur in high gas flow areas near the wellbore. Gas condensate reservoir differs from oil reservoir or gas reservoir in that a series of phase behavior will occur in a condensate reservoir as pressure decreases during development. With pressure dropping down quickly around the well, condensation of oil takes place, leading to the plugging of pores. To better evaluate the influence of non Darcy flow in the Wen Ba reservoir, degrees of turbulent effect on the development performance were analyzed, and development plans based on simulative calculations using different turbulent factors were compared. The results show that the effect of non-darcy flow to development is remarkable in Wen
Ba.

Key words: non-Darcy flow, gas condensate reservoir, development performance
