Abstract


Paper based on the low rank coal Junggar Basin CBM geological features and Xiaocaohu Ida Tun Bao mine owners , deputy , wind well expose the pioneering works of the mine geological data , to determine their general exposition of the development potential of coal bed methane reservoir the three major integrated elements: coal reservoir geology , reservoir characteristics of coal and coal reservoir cover characteristics . Calculated using the Monte Carlo method within the scope of Tun Bao Ida mine and coalbed methane resource abundance , concluded Tun Bao mine coalbed methane resources in the 5% of the total reliability under 0.385 × 10 ~ 8m 3 in a 50% the total amount of the reliability 0.179 × 10 ~ 8m ~ 3, at 95% of the total amount of the reliability of 0.039 × 10 ~ 8m ~ 3; 5% reliability abundance of the resource 0.288 × 10 ~ 8m ~ 3/km ~ 2, at 50% reliability abundance of resources under 0.134 × 10 ~ 8m ~ 3/km ~ 2, at 95% reliability abundance of resources under 0.029 × 10 ~ 8m ~ 3/km ~ 2. Multi-level fuzzy evaluation method to establish a mathematical Xiaocaohu Minefield resource evaluation model , the calculated value of 0.59456 comprehensive evaluation , coalbed methane development level is not conducive to the development of the results of this evaluation mine CBM Hosting Features and future production process gas control has a certain significance.
