摘　　要：为了减少注入/压降试井对整个煤层气井施工进度的影响,基于对煤层气注入/压降试井测试理论及实际操作的研究,提出控制试井测试时间长短的几个因素,应用实例说明其解决方案,结果表明在煤层气井况、设备等基本固定的情况下,对于中高渗煤层,通过提高地面注入压力增大注入量是缩短试井测试时间的重要手段。In order to reduce the impact of the injection/drawdown well test to the whole construction progress of the CBM wells, based on theoretical and practical research of the coal-bed methane injection/down well test, several factors to long or short of testing time for controlled wells are proposed. The applied example indicates its solutions, and the results show that under the basic fixed conditions of coal-bed methane well conditions and equipment, to meddle or high permeability CBM, injection pressure in and other basic fixed for hypertonic seam, it is an important means to shorten the time of well test by raising the surface injection volume.
