Generally speaking

the fracturing can improve the reservoir single well production

however

whether it can reduce the retrograde condensation damage in gas condensate wells or not is urgent to be discussed further. By adopting the indoor core laboratory and single well numerical simulation method

we analyze the impacts of retrograde condensation on the gas phase permeability

the retrograde gas condensate saturation near the wellbore zone

the single well production and the recovery ratio before and after fracturing. The research shows that

after fracturing

the retrograde condensation damage is more serious and the damage time is earlier. However

the fractures reduce the condensate oil critical flow saturation. In the process of the depletion exploitation

the effective permeability value of the fractured gas phase is always larger than the value before fracturing. In addition

the gas phase flow ability increases substantially. After fracturing

the gas recovery speed of the single well is fast

the formation pressure reduces rapidly and the retrograde condensation damage is more serious. Furthermore

the recovery ratio of the condensate oil reduces by 3.48 % and the recovery ratio of the natural gas improves by 6.6 %. Accordingly

it concludes that

fracturing can’t effectively reduce the degree of the retrograde condensation damage

but it can improve the flow ability of the gas phase and the gas production of the gas condensate wells.
