摘　　要：新疆阜康矿区煤储层具有煤层倾角大、厚度大、煤层多、构造复杂等特征,矿区煤层气规模开发进展缓慢,亟需寻找合适的煤层气地质工程一体化开发技术,为新疆煤层气开发提供有力支撑。双管柱筛管完井技术集完井增产一体化,已在沁水盆地推广应用超过400口煤层气水平井。双管柱筛管完井技术从水力冲击作用、清除煤粉、钻井液化学破胶、应力增渗等4个方面对煤层气水平井进行增产改造,助力阜康矿区煤层气高效开发。基于双管柱筛管完井技术特点,从储层煤体结构优势、储层渗透率恢复优势、储层孔裂隙拓展优势、储层构造优势4个方面论述了该技术对于阜康矿区煤层气开发的适用性与应用机理,对新疆类似储层地质条件下的煤层气高效开发具有指导和借鉴意义。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.
