煤层气井产出液煤粉含量监测
Monitoring of produced lfuid of coal content in coalbed methane wells
摘要
Abstract
Lots of slack coals are produced in the production of coalbed methane, and the slack coal concentration cannot be con-tinuously metered. A laboratory test was conducted to assess the compensation of lfow temperature/lfow rate to slack coal concentration, and a method for computing the slack coal concentration in the lfuid produced from the coalbed methane well was established accord-ing to the principle of mass conservation. Furthermore, a real-time monitoring device suitable for slack coal concentration in the lfuid produced from the coalbed methane well was developed. This device can monitor the produced lfuid density value through a differential pressure type density sensor, and transmit the value to data terminal in real time, so that the real-time slack coal concentration of pro-duced lfuid can be obtained through data conversion. Field application shows that the slack coal concentration monitoring device can realize real-time remote data monitoring, with the accuracy subject to the ifeld requirement, which provide bases for the ifeld control of slack coals and the arrangement of production system.关键词
