摘　　要：煤层气采收率的确定对于产业的发展具有较大指导意义。通过对类比法、解吸法、等温吸附曲线法及储层数值模拟法适用性分析,并结合沁水盆地寿阳区块煤储层特征,应用COMET3数值模拟软件,对15号煤储层生产数据进行历史拟合,校正了基础参数,基于不同井距设计了6种不同的井网方案,对各种方案进行了产能数值模拟及采收率预测。根据预测结果总结出寿阳区块采收率与钻井数关系变化规律,指出最优井间距为288m×216m,对应的采收率为50.4%。The estimation of CBM recovery rate has guiding significance in industrial development. Through analogy, desorption, iso-thermal adsorption curve and reservoir numerical simulation methods applicability analysis, combined with coal reservoir characteris-tics in the Shouyang block, Qinshui Basin, using numerical simulation software COMET3, carried out No.15 coal reservoir production data history matching, corrected basic parameters. According to different well spacing designed 6 different well pattern schemes, car-ried out capacity numerical simulation and recovery rate prediction. Based on predicted results summed up relationship between recov-ery rate and well number in Shouyang block, pointed out that the optimal well spacing is 288m × 216m, corresponding recovery rate is 50.4%.
