摘　　要：不同的煤岩类型其物理性质不同,在测井曲线上均有响应。在岩电关系研究基础上,确定了不同煤岩类型电性参数分布区间,建立了煤岩测井解释图版;提出了灰色关联法解释煤岩方法,该方法考虑因素多,便于计算机自动逐点解释。依据实际生产数据,建立了产能预测图版,新井完钻后即可分析未来产能情况,为产能规划、建设、措施实施提供了依据。Abstract： Different coal types with different petrophysical properties have different responses on the log curves. Based on the rock-electricity relation research, different coal types electrical parameter distribution interval is determined, and a coal rock logging interpretation chart is established. The chart is quick-look and visual, and the single coalbed is quickly interpreted. The grey correlation method is also put forward to explain the coal rock, and good effects have been obtained in practical application. According to the actual production data, the productivity prediction chart is established, future capacity of the new well is analyzed after finishing drilling, which provides the basis for eoalbed gas productivity planning and the gas well construction.
