Method, system, device and storage medium for predicting initiation of rock fractures

Abstract: the present disclosure provides a method, system, device and storage medium for predicting the initiation of rock fractures. the method comprises: obtaining rock fracture data in the reservoir, establishing a double fracture model, applying confining pressures of different strata to the boundary of the double fracture model to change stress differences of horizontal confining pressures and obtain different horizontal stress differences, analyzing the corresponding stress changes of maximum principal stresses and maximum shear stresses on both sides of a fracture and a fracture tip as the horizontal stress differences change, and obtaining a stress state at the fracture tip and both sides of the fracture, predicting whether the fracture is initiating. the method can quickly clarify the fracture initiation law and characteristic, analyze the stress state at the fracture tip and both sides of the fracture, and thus improve the accuracy of fracture initiation prediction.
