【摘要】：煤粉产出是影响煤层气井连续、稳定排采的重要因素之一。归纳总结了煤粉浓度监测的4种方法:无标样的目视法、有标样的色度对比法、称量法和煤粉浓度监测仪监测法;分析了临汾区块影响煤粉产出的煤储层静态地质因素和煤层气开发动态工程因素;基于临汾区块煤层气井产出煤粉浓度的现场连续监测数据,利用测井解释与回归分析等方法,建立了煤粉浓度与构造煤厚度、套压的相关关系。
[Abstract]:Pulverized coal production is one of the important factors affecting the continuous and stable drainage of coalbed methane wells.Four methods of pulverized coal concentration monitoring are summarized: visual method without standard sample, colorimetric contrast method with standard sample, weighing method and monitoring method of pulverized coal concentration monitor.The static geological factors of coal reservoir and the dynamic engineering factors of coalbed methane development in Linfen block are analyzed, and the methods of log interpretation and regression analysis are used based on the field continuous monitoring data of coal powder concentration produced from coalbed methane wells in Linfen block.The correlation between pulverized coal concentration and tectonic coal thickness and casing pressure was established.
