Research Progress on Hydraulic Fracturing Test and Numerical Simulation of Fractured Reservoirs

Due to the influence of geological conditions, there are a large number of natural fractures or cleats distributed in the reservoir, which directly affect the effect of hydraulic fracturing. In order to clarify the mechanism of action between hydraulic fractures and natural fractures, the current research on hydraulic fracturing fracture propagation in fractured reservoirs is reviewed from two aspects of experiment and numerical simulation. Firstly, the research progress of experiment is introduced. Then, the related research of numerical simulation is expounded. Finally, the general conclusions of hydraulic fracturing in fractured reservoirs are summarized, and the future research is prospected.
