Abstract
Fracturing fluid flowback is a principal process in the successful development of unconventional oil and gas reservoirs. When a flowback rate is low the fracturing fluid remains in a reservoir, causing damage to the reservoir and impacting the oil and gas capacity during the development stage. The current study of the factors that affect a flowback rate of a fracturing fluid is poor. This thesis is focused on an impact study of the reservoir geological characteristics on the fracturing fluid flowback. The roles of reservoir lithology, physical properties, formation pressure, fracture development, and wettability on fracturing fluid flowback are analyzed. The conclusions are expected to serve as a reference for further development of shale oil and gas reservoirs. After the simulation work, we conclude that when the formation pressure is higher, the total flowback rate increases; for reservoir wettability, the less water wet the reservoir is, the more the total flowback rate has. The influence of fracture development is diversified; a fracture location will determine whether it becomes promotion or resistance to the fracture fluid flowback process.
