For the CBM enrichment and high yield,the reservoir quality,sealing quality of roof and floor and completion quality (three qualities) play a decisive role.According to the log,laboratory analytical data of coal core,logging evaluation methods for main controlling factors of “three qualities” in CBM reservoir are discussed in detail.The quantitative evaluation methods of “three qualities” are established by the main controlling factors of organic fusion mean.Based on these methods,“three qualities” of CBM reservoir in the study area are carried out through quantitative evaluation.The results show that those methods can evaluate “three qualities” of CBM reservoir quantitatively and effectively.The evaluation results are closely consistent with the tests of laboratory analysis and fracturing dynamic drainage results.For the 11# CBM reservoir,the reservoir quality of the central area is much better than that in the northeast and southwest,the one in the northeast is slightly better than the southwest;Overall,the sealing quality of roof and floor block of the 11# coal seam is good.The sealing types are mainly Ⅰ,Ⅱ,the area with good sealing quality locates in the middle of the study area,the poor area locates in the northeast and southwest of the study area;The greater the brittleness index and the stress difference between coal seam and its roof and floor,the smaller the difference coefficient of coal seam stress,and the higher the coal structure index.Then the fracturing of coal seam is strong,the productivity effect is remarkable after fracturing drainage.To obtain high-yield in CBM wells,it requires not only good reservoir quality and sealing quality of roof and floor block,but also the completion quality of fracturing zone,which is an important factor that cannot be ignored.
