The coal reservoir in Fukang mining area of Xinjiang has different characteristics of large inclination angle

large thickness

multiple coal seams and complex structure

and the development progress of coalbed methane（CBM） in the mining area is slow. It is urgent to find a suitable integrated development technology for CBM geology engineering conditions to provide strong guidance for the development of CBM in Xinjiang. The dual-tubing screen completion technology integrates the completion and stimulation

and has promoted and applied more than 400 CBM horizontal wells in the Qinshui Basin. The dual-tubing screen completion technology has increased the production of CBM horizontal wells from four aspects

such as hydraulic impact

carrying pulverized coal

chemical gel breaking of drilling fluid

and stress permeation

so as to help the efficient development of CBM in Fukang mining area. Based on the technical characteristics of dual-tubing screen completion

the applicability and mechanism of this technology for the development of CBM in Fukang mining area is discussed from four advantages: reservoir coal body structure

reservoir permeability recovery

reservoir pore fracture expansion

and reservoir structure

and has guiding and reference significance for the efficient development of CBM under similar reservoir geological conditions in Xinjiang.
