Abstract: Using coalbed methane(CBM)effectively not only reduces safety hazards in coal mining but also lessens its harmful effects on the atmosphere.As a clean energy alternative, CBM has grown into a significant addition to natural gas resources with its extraction efforts increasing annually.To tackle the difficulties of perforation monitoring in CBM's bridge plug and perforation combined operations, the vibration characteristics and transmission characteristics of the perforating charges produced by the plug-and-perf are analyzed.A perforation monitoring system based on virtual instrumentation is designed, and this system utilizes high-precision piezoelectric accelerometers and data acquisition cards to capture vibration signals from perforation, while LabVIEW is adopted for developing the software.The system was successfully used to monitor cluster perforations during a bridge plug and perforation combined operation in shaft XX of Linxing area of Shanxi Zhonglian CBM,yielding highly effective results.The deployment of this project is beneficial for enhancing the safety of bridge plug and perforation combined operations, playing a crucial role in safeguarding wellbore integrity and the well-being of personnel in perforation operation.
