Note. Fracture conductivity: after the fracture is closed, the proppant filling zone can pass through the reservoir fluid. Diversion retention rate: determination of the ratio between the conductivity of fractured support and the diversion capacity of formation water measured by hydraulic fracturing after fracturing. Diversion damage rate: the decrease of the diversion capacity of the support fracture induced by the fracturing fluid relative to the formation water.
