摘　　要：基于优选的柿庄南区块22口煤层气井,从定性、定量角度分别采用曲线分类分析法和曲线特征值分析法综合分析各井的产量规律。通过曲线分类分析法,确定了不同类别井的判断标准,将柿庄南区块22口井分成四类:稳步上升+平稳高产井、稳步上升+稳步下降井、曲折上升+平稳高产井、曲折上升+稳步下降井。通过曲线特征值分析法,有效找出各曲线特征值之间的相互联系,得出产量规律。The law of production can be obtained comprehensively on both qualitative and quantitative methods by analyzing the 22 wells optimized from south block of Shizhuang. These methods are based on the classifications and eigenvalues of production curves respectively. With the first method, the judgment standard of classifications is determined and these 22 wells are divided into four categories： the well with the production cure rising stably first and staying at high production level afterward, the well with the production cure rising stably first and declining stably afterward, the well with the production cure rising circuitously first and staying at high production level afterward, the well with the production cure rising circuitously first and declining stably afterward. With the latter method, the relationships of each eigenvalues of production curves can be found.
