Abstract

In this article, the mathematical model of static hydraulic fracture under constant fluid pressure interaction with natural fracture is created. The model describes mechanisms natural fracture opening and closing and its frictional sliding. Also, the parametric study of the secondary hydraulic fracture initiation at the natural fracture is performed, and the point of this re-initiation is found. For the first time not only qualitative, but also quantitative evaluation of possibility and point of the fracture re-initiation is done. The comparison of obtained results with the results of fully coupled model, including quasi-static fracture propagation and fluid flow inside it is performed. This comparison shown that the created static model is really applicable to the prediction of hydraulic fracture reinitiation at the natural fracture.
