【 摘 要 】

In this paper, the combined method of laboratory experiment and theoretical analysis is applied to the research process of Characteristics of cracks. Through analyzing the dynamic response of the oil and water wells in the block, the characteristics of the fracture development are studied. The size and direction of ground stress are obtained through indoor experiments, such as sound velocity, differential strain analysis and Paleomagnetism, and combined with the experimental test of the outcrop. establishing the rock fracture criteria in Aonan oilfield, giving relative logic formula of the deduced stress and fracture parameters, so as to accurately describe the characteristics of crack distribution of different wells.
