The compressive stress induced by the effect of the fracturing fluid on the rock around the fracture in the process of the hydraulic fracturing are analyzed in this paper,the influence range and changing trend of the stress are provided as well by using the finite element method,which is based on rock mechanical properties and the characteristics of earth stress. The results provide the suggestion for the cluster spacing optimization of the horizontal well fracturing.
