However, in a tight sandstone reservoir, a conventional fracturing fluid flowback model (forced flowback technique) is still used to improve fracturing performance. To eliminate secondary damage due to the remaining fracturing fluid in hydraulic fractures, a forced closure technique is always used after a hydraulic fracturing treatment.
