摘　　要：连续、稳定排采对煤层气井生产至关重要,任何影响因素的弱化和滞后都会影响到煤层气井的整体排采效果。本文系统分析煤层气井排采动态预警的3种方法:指标预警、规划预警和趋势预警,开发了指标预警系统,在示范区应用效果良好,为煤层气田开发动态预警提供了一条新的途径。Continuous and stable drainage is crucial important for CBM production, and the weakening and delay of any influencing factors will affect the overall drainage of the CBM well. The paper systemati- cally analyzes the three methods of dynamic early warning for CBM drainage, including index early warn- ing, planning early warning and trending early warning, and develops the index early warning system which has achieved good result after applied in the demonstrations, and provides a new path for the dy- namic early warning for CBM field development.
