摘　　要：柳林煤层气试验区是我国第一个进行规范煤层气小井网试验的区块 ,本文描述了该区煤层气藏地质模型 ,并应用煤层气数值模拟技术 ,在对该区煤层气藏的几项主要参数进行敏感性研究和对生产情况进行历史拟合的基础上 ,对该区煤层气藏的产能进行了预测 ,结果表明 ,单井平均日产气量较低 ,煤层气可采储量规模偏小。但其埋藏浅 ,外围蕴藏着十分丰富的煤层气资源 ,如连片规模开发 。Liulin test zone of coal-bed gas is the first area to conduct the regular test of small well network for coal-bed gas. The article describes the geological model of the coal-bed gas reservoir in the area. With numeral simulation (software) of coal-bed gas,based on the sensibility study of some main parameters and the historical fitting of production situation of the coal-bed gas reservoir,the productivity of the coal-bed gas reservoir is predicted. The results show the average daily production of a single well is low,and the recoverable reserves of the coal-bed gas reservoir is small. But the reservoir is buried shallowly. There is very rich resource of coal-bed gas on the skirts of the area. There is great E & D potential for coal-bed gas if large-scale continuous development is performed.
