摘　　要：赵庄煤层气井水中富集产甲烷菌群,可优化产气能力。采用厌氧富集得到本源菌群,通过正交试验优化产气条件。水样中存在产甲烷菌群,实验室条件下最优产气条件:NH_4Cl为1. 0 g/L,K_2HPO_4为1. 5 g/L,MgCl_2为0. 1 g/L,煤粉添加量160 g/L,60 d产甲烷量达18. 07%。赵庄井田产甲烷菌群通过富集可以降解无烟煤产气,通过条件优化可提高其降解无烟煤产气的能力。There exists methanogenie bacteria in the water of Zhaozhuang coal seam gas well, and its gas production eapaeily can be optimized. The original bacteria group was obtained by anaerobic enrichment, and the conditions of gas production were optimized by orthogonal test. Methanogenie bacteria existed in water samples. Under the laboratory conditions, the optimum biogas production conditions were NH4 CI：1. 0 g/L, K2 HPO4：1.5 g/L, MgC12：0. 1 g/L,and the amount of coal powder added was 160 g/L. The methane yield of 60 d was 18.07%. The aeeumulation of native bacteria can make use of anthracite to produce methane,and the gas yield can be improved by optimization.
