摘　　要：采用自行研制的国家发明专利测试仪器,对地层煤板进行了支撑剂嵌入实验研究。考察了在不同支撑剂类型、不同支撑剂粒径、不同铺砂浓度、不同闭合压力下支撑剂嵌入对裂缝导流能力的影响。实验结果表明:随着闭合压力增大,石英砂的导流能力快速降低;铺砂浓度越大,支撑剂充填层抗压能力与抗破碎能力越强,裂缝导流能力越高。In this paper,an experimental study about proppant embedment for the stratum coal board has been done by using a self-developed new test instrument which gains China national invention patent. The experiment has investigated the influence on fracture conductivity under some different factors which include the type of proppant,particle size of proppant,concentration of sanding and closure pressure. It is found that the quartz sand diversion capacity quickly reduces with increasing closure pressure. And at the same time as the sanding concentration increasing,the proppant pack compressive ability and the ability to resist breaking become stronger; the fracture diverting capacity becomes higher.
