Study on Improving Gas-condensate Well Productivity by Huff and Puff Dry Gas Injection

Dry gas injection huff and puff is one of the effective techniques to remove the retrograde condensate blocking of condensate gas wells. A composition simulator is used to establish a single well radial model for numerical simulation based on fluid and geologic parameters of a sample gas condensate well. The changing laws of retrograde condensate saturation and gas relative permeability changing along the radial direction are studied during the depleted production process of gas condensate well, and also the production process after dry gas injection. The changes of normalized production coefficient both before and after huff and puff gas injection process are contrasted. The results show that retrograde condensate bank is formed at the range of 5 m near the wellbore, after bottom hole flowing pressure draws down the dew point pressure, which result in sharp decrease of gas well productivity. Retrograde condensate saturation near wellbore can be effectively reduced by dry gas injection huff and puff, and the productivity of gas well can be raised by removing of retrograde condensate blocking near well bore. The higher the injection volume is, the better effect of huff and puff will be, but there exists an optimized gas injection volume. In this example, the optimized dry gas injection volume is 200×10~4m~3, beyond this volume, the increase of gas relative permeability will be lowed.
