摘要
介绍了用于压裂煤层气矿床的超轻型焦炭支撑剂的生产情况。原材料是高炉焦炭、铸造焦炭和焦炭微风。采用这种方法生产的焦炭支撑剂符合 ISO 13503-2:2006/Amd.1:2009《水力压裂支撑剂》标准的所有要求，但抗压强度除外。它们的孔隙率最高可达 40%，主要是大孔材料，主要含有圆柱形孔隙，较少含有瓶形或楔形孔隙。压碎率最低的支撑剂来自高炉焦炭（CSR > 65 %）。
Coke-based proppant for coalbed methane technology
The production of ultra-light weight coke proppants for fracturing coal bed methane deposits is presented. The raw material is blast-furnace coke, foundry coke and a coke breeze. The method used obtains coke proppants that meet all the requirements of the ISO 13503-2:2006/Amd.1:2009 standard for proppants used in hydraulic fracturing, with the exception of crush resistance. They have porosity up to 40 % and they are mainly macroporous materials, containing predominantly cylindrical, less frequently bottle-shaped or wedge-shaped pores. The proppants with the lowest crush rate were obtained from the blast furnace coke (CSR > 65 %).
期刊介绍：
The International Journal of Coal Geology deals with fundamental and applied aspects of the geology and petrology of coal, oil/gas source rocks and shale gas resources. The journal aims to advance the exploration, exploitation and utilization of these resources, and to stimulate environmental awareness as well as advancement of engineering for effective resource management.
