煤层气生产过程中，需要随时了解和掌握煤层气井的产水、产气、液面高度等各项参数，以便根据生产阶段的需要及时调整生产参数，使煤层气井的生产处于最佳状态。目前国内煤层气抽采过程中仅能单独测量压力、温度、液位等参数，并不能检测每个层位的产气产水量，因此为了达到长期同时监测不同层位煤层的目的，设计了煤层气井流体原位实时监测仪。该监测仪不仅能测量温度、压力等参数，还可结合地面测得的气、水流量，分别得出不同层位煤层的产气产水量，为煤层气开采方法的确定提供科学依据，有利于提高煤层气抽采率。

It’s necessary to know in time various parameters such as produced water, gas, and liquid height during CBM (coal bed methane) production so as to adjust production parameters according to the production stage and needs in a timely manner, so that the production of CBM wells is in the best conditions. The in-situ real-time CBM monitor detects mainly the key parameters, including pressure, temperature, flow, vibration and liquid level to achieve the purpose of real-time monitoring of the fluid situation in borehole. These parameters reflect the produc-tion, water flow and loss of volume during drilling, and further clarify the coal reservoir pressure, the releasing rate of gas and the distribution of various coal reservoirs to provide the most intuitive and scientific data for the com-prehensive CBM development .
