Abstract In hydraulic fracturing，there are always some puzzling phenomenon such as premature sand-out and abnormally high treatment pressure. In recent research of hydraulic fracturing，experimental and numerical simulations are performed on the effect of stress and perforation on fracture propagation at near-wellbore region. The results show that hydraulic fracture propagation is not only related to the orientation of borehole in the stress field，but the magnitude of principal stresses. In addition，these research results provide some suggestions on diagnosing potential fracture reorientation and eliminating the effect during hydraulic fracturing treatment.
