Modeling Hydraulic Fracturing near Circular Underground Opening in Triaxial Compression
Abstract
The article describes the numerical studies on propagation of hydraulic fracture in the nonuniform-stress elastic environment around a cylindrical cavity. The modeling used the extended method of finite elements. The scope of the modeling embraced different variants of the principal stress orientation relative to the cavity and a disk-shaped initiation fracture. The influence of the stress ratio and stress level on the fracture path is described. The main types of the created fractures are shown. The conditions when the created fracture reaches the cavity surface or propagates along it are analyzed. The features of the fracture propagation and opening pressure are described for the fractures of various shapes depending on the volume of the injection fluid.
