摘　　要：从煤层气井解吸机理出发 ,对DST和注入 /压降两种测试方法在解释曲线和解释结果上的差异进行分析对比 ,从取得完善可靠的资料角度得出两种不同方法所适应的煤层气勘探开发的阶段不同。From the desorption mechanism of coal bed, the comparison and analysis are made to the difference of two test methods between DST and injection/draw-down on interpretation curves and interpretation results. From point of view of getting reliable and perfect data,this paper summarizes the different coal gas exploration and development stages that the different methods are suitable for.
