Srv Calculation Method of Dry Hot Rock Based On Microseismic Fracture Network Model

Microseismic monitoring is one of the most important geophysical methods in fracturing monitoring, and is also an important research content of dry hot rock development plan in the world. There are many methods to calculate SRV （Stimulated Reservoir Volume） by the spatial distribution of microseismic events，and we choose to calculate SRV based on fracture network model. Firstly, the continuous hydraulic fracture network is modeled based on the time-space distribution of microseismic events. Then, the linear fracture network is expanded into columnar fracture network based on fracture height and influence radius. Finally, the volume of the whole fracture network is calculated. This method is more suitable for SRV calculation of hot dry rock, considering fracture height and fracture influence radius.
