摘      要：Fracture is a common underground structure phenomenon,which can provide space and passage for the storage and migration of oil and *** radar is a fast and high-resolution geophysical detection method,which has been widely used in engineering,exploration and other *** paper mainly uses theoretical analysis and numerical simulation to study the variation law of the characteristics of the received borehole radar signal with the variation of fracture *** Ricker wavelet is used as the pulse signal of the borehole *** results show that the amplitude of the signal received by the borehole radar first increases,then decreases,and finally tends to be a stable value with the increase of fracture *** results have guiding significance for the detection of underground fractures and the estimation of fracture width by borehole radar.
