| 摘 要： | 基于我国目前煤层气产能最高的DT3井和TL007井所处的地质构造背景、煤层气排采历史和排采参数的对比分析，结合煤储层物性实验成果，发现理论计算的饱和度和临界解吸压力与实际排采不一致，指出了控制煤层气产能最关键的参数是煤储层的相对渗透率和井底压力，提出了平衡开发是煤层气产能稳定、持续的重要保证。

| Abstract: | Based on analogy about recovery parameters, recovery histories and geological tectonic background of well DT3 and well TL007 which possess the highest coalbed methane (CBM) productivity in China at present, integrated experimental results of coal reservoir physical properties, it is found that computational saturations and critical desorbing pressures by theory are not in accord with practical recovery ones.It is pointed that the key parameters of controlling CBM productivity are relative permeability and well-bottom pressure.And it is put forward that equilibrium development is the important guarantee with stable and sustainable CBM productivity. |
