| 摘 要： | 沁水盆地煤层气田为高煤阶煤层气田是目前国内已商业化开发的最大的的高阶煤煤层气开发区。在煤层气开发实践中暴露出一个突出的问题，煤粉生成、运移，裂隙、人工裂缝被煤粉堵塞，导致煤层渗透性的永久性伤害，使得气／水产量难以达到理想状态。通过现场及室内实验资料，本文探讨了煤粉的产生原因并提出了相应的防治措施。

Discussion of Technique of Coal powder Prevention and Treatment for Qinshui Basin CBM wells During Dewatering and ExtractionProcess |
| |
| Abstract: | Qinshui Basin CBM Field, high-rank coalbed methane field is currently the largest commercial development of coalbed methane high-level development zones. CBM development in the practice revealed an outstanding problem, coal generation, migration, fracture, artificial fracture was pulverized blocked, resulting in the permanent damage of coal permeability, making the gas/water production difficult to achieve the ideal state. Through field and laboratory data, this paper discusses the causes of coal powder and the corresponding control measures. |
