摘　　要：贵州省主要含煤地层形成于晚二叠系龙潭组,煤层层数多,单层厚度小,以薄及中厚煤层为主。特殊的地质条件对煤层气试井提出了新的要求。为了在薄-中厚煤层群等典型地质条件下进行煤层气试井测试,并获得准确的煤储层参数,本文考虑了煤层气藏与常规天然气藏的地质差异,从煤层气试井的地质适应性角度探讨了薄-中厚煤层群等典型地质条件试井工艺要求,为煤层气试井设计提供参考。Mainly coal-bearing strata of Guizhou province, were formed in the late permian Longtan formation coal layer, thickness is small, mainly for thin and thick coal seam. Specialgeological conditions of coal-bed gas well testing puts forward new requirements. To in thinin the thick seam group,typical geological conditions for seam gas try well test, and getaccurate of coal storage layer parameter,paper consider has seam gas hid and general gas hid of geological differences,from seam gas try well of geological adaptability discussion hasthin-in the thick seam group,typical geological conditions try well process requirements, for seam gas try well design provides reference.
