根据对韩城示范区的地质条件以及煤层气井的生产动态资料进行研究，从含气量、构造、埋深和煤厚方面分析其对煤层气井产能的影响，认为煤层含气量大、构造简单、埋深在400-600m以及煤层厚度大等地质条件有利于煤层气井产气；通过比较区内77口井的产气产水特征，重点分析了井底流压、套压等排采参数与产气、产水等生产数据的关系，认识为排采过程中，保持较低的井底流压、稳定的产水量和合理的层间合采方案能获得较高的产气量。

Researches have been carried out based on geological conditions and CBM well dynamic production data in the Hancheng model area. From aspects of methane content, structure, buried depth and coal thickness analyzed their impacts on CBM well productiv-ity, considered that owing to geological conditions of large coal seam methane content, simple structure, 400~600m buried depth and large coal seam thickness are all propitious to CBM well production. Through comparison of 77 wells methane and water yield character-istics, focused on analysis of relationship between drainage parameters of bottom hole pressure, casing pressure and production data of methane and water yielding, considered that during the drainage, to keep lower bottom hole pressure, stable water yielding and rational multi-layer drainage scheme can obtain higher methane yield.
