The construction scheme and application of coal-bed methane (CBM) well monitoring system

Coal-bed Methane (CBM) development is a new energy industry to develop greatly in china. The paper comprehensively summarizes the construction scheme of monitoring system of CBM wells. By combining the CBM development in Hancheng area, the scheme formed a system of CBM production regulations. The study proposed the main technical parameters and related processes of quantitative automatic production control for different type of wells (vertical wells, horizontal wells). And based on the full investigation and analysis of the current related technologies, through digestion and absorption, integrated innovation, self-development and the combination of industry research, the automatic CBM production control technology was formed with independent intellectual property rights, including remote CBM production information collection technology, information transfer and communication technology, quantitative analysis methods, software packages, and control norms etc. Field production test proved that the construction scheme of monitoring system of CBM wells could fully meet the domestic demand of CBM wells production.
