Abstract:In order to detect the fracture information inside the material, solve the problem of static flaw detection and dynamic monitoring of the material, this paper studies the processing method of acoustic emission signal based on the active excitation signal of shale surface and the data output from hydraulic fracturing test. Event detection is the preliminary signal processing, to obtain the event information conveyed by acoustic emission signal and capture the information of shale internal materials carried in s… Show more
