摘　　要：煤层气排采通常依靠人工进行排采制度调整,针对这种简单、低效、落后的工作方式,设计了能够满足煤层气排采实际工况需求的智能化排采系统,该系统能够根据煤层气井的井况和采油工程人员制订的排采制度自动、智能化地进行煤层气排采。为了保证系统的稳定性和抗干扰能力,采用了基于模糊控制的PID控制算法,通过在某煤层气排采现场的实际应用验证,整个系统有效、稳定、安全可靠。Drainage process adjustment of CBM has been depending on manual operation. Contrapose to such a simple, inefficient and backward working mode, one intelligent pumping system to adapt to actual working condition of CBM drainage is designed. This system can drain automatically and intelligently based on CBM well condition and drainage schedule formulated by oil production engineering staff. Fuzzy control based PID control algorithm is applied to guarantee systems＇ stabilization and anti-jamming ability. According to practical test result from one CBM drainage site, it is concluded the whole system is effective, steady, safe and reliable.
