The basic principles and methods of measuring artificial fractures using AEO-4 A rock acoustic emission positioning system and quantitatively determining the development status of natural fractures by using principal curvature method are summarized. The hydraulic fracturing and artificial fractures formed by high pressure water injection and the natural fractures are summarized The distribution pattern of cracks is pointed out, and the orientation and plane distribution of cracks are pointed out. The results of the research on fractures are analyzed, such as the design of newly adjusted wells in the development and production of oilfields, the adjustment of injection well pattern, the selection of fracturing well parameters and the dynamic dynamic water injection management
