摘　　要：根据水煤浆分散剂分散性能的评价方法,筛选出了两种分散性能良好的阴离子型分散剂FSJ-01和FSJ-02。设计了一种适合煤岩煤粉的分散导流实验,并对所筛选的分散剂进行了评价研究。最终优选出具有分散性能良好、价格低、货源广等特点的分散剂FSJ-02作为煤层气压裂改造用的煤粉分散剂。According to the evaluation method（static stability） for CWS dispersion agents,screened two kinds of anionic dispersion agents FSJ-01 and FSJ-02 with very good dispersing properties.Furthermore,designed a new experiment method to evaluate the influence of coal fines dispersion on the conductivity of propped fracture.Research data show that the coal fines make great damage to the conductivity of propped fracture,and adding dispersion agents can reduce coal fines damage and improve conductivity.Finally,FSJ-02 was optimized as dispersion agent of coal fines used for CMB stimulation because it has a excellent dispersing ability,low price,adequate supply and so on.
