Abstract: Deep coalbed methane resources(coal seam depth in 1 000-2 000 m)is 22. 5×1012 m3 in China,accounting for 61. 2% of the total resources. How to improve the single well production and form relative development strategy is a research focus in China. Through statistical analysis of geological parameters and production data of trial production wells in Daning-Jixian block,it shows that the deep coal reservoir has the characteristics of low permeability,micropore development and low recovery coefficient. The cluster wells have the characteristics of long term low production,slow and long production period,and the L type horizontal well has the characteristics of short production period and high gas production. On the basis of above,the index system for evaluating the productivity of deep coal bed methane is es- tablished. The factors that affect the effect production of deep coalbed methane include three major categories: geolog- ical conditions,engineering technology and quality and management. Therefore,in order to improve the single well pro- duction of deep coalbed methane,the evaluation and prediction of high yield area with the focus on recoverability needs to be well done,and geological and engineering integration design of the fracturing parameters optimization and the well spacing well spacing requires to be carried out. The engineering quality management needs to be reinforced in order to reduce the damage of the reservoir and realize the long continuous production.
