摘要:

通过井下煤储层观察查明了井下原生煤粉主要呈构造煤集合体状态赋存,根据其赋存特征分为断层煤粉源与顺层煤粉源,将井下原生煤粉与煤层气井产出的煤粉进行煤粉成分与微观特征的对比研究,发现煤层气井产出煤粉的煤粉成分与微观特征都与顺层煤粉特征一致,说明煤层气井的煤粉来源主要为顺层煤粉源。查明煤层气井煤粉的特征与来源为控制煤粉产出奠定了科学基础。

Abstract:

Based on the observation of coal reservoir in coal mines,it was found out that the structural coal aggregates are the main occurrence of primary coal powder.According to the occurrence characteristics,the primary coal powder can be divided into fault coal powder and coal powder along seam.The comparative research on the compositions and microscopic characteristics of coal powder showed that the characteristics of coal powder produced from CBM wells were similar to coal powder along seam.Therefore,the coal powder produced from CBM wells are coal powder along seam.This research establishes the basis for the controlling of coal powder.
 

Key words: CBM well, Coal powder, Tectonic coal aggregate, Coal powder along seam, Fault coal powder
