Study on low cost transmission technology of coalbed methane well production data

In order to realize a fine control on the gas drainage production of the coalbed methane field in a remote mountain area, it was necessary to break throu gh the traditional method of the human patrol or internet between the well fields and the low cost technology could be applied to realize the gas drainage data collection and transmission. According to the small dimension, flexibility and high geology adaptability and other advantages of the industrial unmanned aerial vehicle, the industri al unmanned aerial vehicle with the air to ground data communication module was provided. With the coordinative operation between the communication software and t he flight control software, according to the well geographical position and the high altitude optimized flight path as well as the flight speed, practices on the application of the industrial data transmission were conducted on the coalbed methane field with many year commercialized productions. The result showed that at present, after th e data reading, the 24 h continued data could be stored at the site and the one-time data transmission would be realized. The data continuity was improved by 10 times higher than the traditional human patrol method. The previous gas well patrol and meter reading mission could be completed only with 10% vehicles and personnel man ual patrol of the previous manual patrol, 65% patrol time of the previous single shift and 50% well filed patrol miles of the previous single shift. Thus the cost reduction and benefit increased of the production could be realized in the coalbed methane field.
