摘要
为了实现复杂环境下对煤层气试井过程中的流量和压力参数进行自动控制,解放劳动力,减少试井成本,设计了一套煤层气注入/压降地面监控系统。该系统以流量传感器和压力传感器为基础,通过单片机中的PID控制算法在不超过最大注入压力的条件下实现恒流注入。实验结果表明,该系统可以在复杂环境下对试井过程中的流量和压力参数进行自动控制。
In order to realize the automatic control of the flow and pressure parameters in the test process of CBM under complicated conditions, liberate the labor force, and reduce the test cost, a set of CBM injection/pressure drop ground monitoring system was designed. Based on the flow sensor and pressure sensor, the system achieves constant current injection under the condition of not exceeding the maximum injection pressure through the PID control algorithm in the single chip microcomputer. The experimental results show that the system can automatically control the flow and pressure parameters in the well testing process in a complex environment.
