| Abstract: | Aiming at the demand for real-time monitoring of perforation initiation in the petroleum industry,aperforation initiation monitoring system based on the acceleration characteristics of tubing vibration was designed.After the perforating gun is detonated,a high-sensitivity acceleration sensor is used to collect the vibration signal of the oil pipe,and the vibration signal is processed by apost-conditioning circuit.The processed signal is collected by a high-speed acquisition card,and the time-frequency characteristics of the signal are analyzed.The signal extraction module extracts the shortterm energy characteristics of the signal after preprocessing,and judges the initiation of the perforating gun.In the tubing vibration experiment of different perforating gun initiation conditions,this monitoring system can realize the perforation gun initiation monitoring with the perforation depth of 1100~3200 m without a priori.The system is simple to install and fast in processing speed,and can be integrated into an embedded system for use in the future,laying the foundation for real-time monitoring of perforation initiation. |
