摘　　要：煤层气藏主要形成条件包括煤层厚度、煤阶、埋藏深度和保存条件等4个方面。通过分析韩城地区煤层这4个方面的特征和对成藏条件的综合评价，认为该区煤层厚度大、煤变质演化程度高、保存条件好，易形成良好富集高产煤层气藏，符合商业开采深度（埋深在500～1500m范围内的煤层占全区的80％以上）。The research of CBM formation included the generation, conservation, migration and deposition. The main conditions of CBM formation include four factor：coal seams thickness, coal ranks, burying depth and conservation condition. Iin Hancheng, these four factors were analyzed and integrative evaluated. It was proved that there are the big coal seams thickness, high evolution, and appropriate rank in the area. Most burying depth is 5004- 1 500 m. Moreover, the area of economical depth and good preservation condition is over 80%. In sum, the formation condition of CBM was superior in Hancheng area and the high enrichment CBM reservoir easily formed.
