摘　　要：针对沁水盆地寿阳区块煤层气井产粉严重的问题,连续采集井口煤粉溶液样品,在实验室测试获取了煤粉浓度、煤粉粒径和煤粉形态等煤粉产出特征。通过测井曲线和构造曲率判识了煤体结构特征,利用数据描述分析和Pearson相关系数计算方法定量分析了产粉特征与煤体结构相关性。研究成果为寿阳区块煤层气产粉规律研究和控粉措施提供了实验数据和理论指导。To address the serious problem of CBM well coal fines production in the Shouyang block of the Qinshui basin,coal dust solution samples were continuously collected from wellheads and laboratory tests were conducted to obtain the coal fines production characteristics such as coal fines concentration,coal fines particle size and coal fines morphology.The coal structural characteristics were identified through logging curves and tectonic curvature,and the correlation between pulverisation characteristics and coal structure was quantified using descriptive data analysis and Pearson correlation coefficient calculation methods.The results of the study provide experimental data and theoretical guidance for the study of the CBM production pattern and pulverisation control measures in the Shouyang block.
