摘　　要：我国的煤层气资源十分丰富 ,但煤层的地质条件复杂 ,类型多样 ,明显不同于国外某些煤层气资源开发较为成功的国家和地区。根据煤层特性及煤层气赋存特点、产出机理 ,对煤层气排采设计和设备选择作了论述。通过实际排采曲线分析 ,在总结十多口井排采经验的基础上 。According to the coalbed gas characteristics,such as storage properties,absorbed properties and the producing theories,we discussed designing of pumping and producing technology and the selection of the equipment.By analyzing more than 10 wells' test data,we get the factors which affect the pumping and producing efficiency and the effect mechanics.
