Research and application of gas drainage measurement and monitoring system in surface wells

Abstract

In view of the problems of poor reliability and low accuracy in the monitoring and measurement of gas drainage in surface wells, a set of separate measurement and monitoring system for gas drainage in surface wells has been formed through the research on extraction detection, field self-powered supply, distributed measurement point data acquisition, measurement and monitoring device. The system provides a complete set of technology and equipment for real-time on-line monitoring of surface wells, and improves the accuracy of surface well measurement. At the same time, the surface well gas extraction data is combined with the downhole monitoring system data in real time, which realizes the safety and effective monitoring of mine drainage.
