Abstract: In recent years, inspired by the seismic attribute analysis technique, a new method of logging attribute analysis of shale fractured oil and gas reservoirs has emerged. In order to avoid the conventional logging signal is subject to noise interference thus affect the fracture recognition effect, the paper studies the fracture recognition based on the wavelet transform method. Taking the shale fractured oil and gas reservoirs of the Lower Cambrian Niutitang Formation in the Cengang block of Guizh... More
