摘要
本文通过对阜新矿区研究区域的实际排采数据的统计分析,验证了"岩浆岩和断层是气体富集主控因素"在该区的存在,针对产水、产气部位、层位不清的问题,提出了:"围岩及地下水动力条件也是影响气体赋存的另外两个主控因素"的观点,丰富了该区富集规律认识,在此基础上,划分了开发单元,总结了各单元排采规律,破解了生产中遇到的瓶颈问题,为该区及相似地区煤层气井部署、排采管理等提供依据和借鉴。
The paper proves that igneous rock and faults is two main factors for CBM occurrence through analysis of production data. In view of the uncertainty of water or gas bearing localization and formation, it proposed that the groundwater dynamic condition and the lithology of roof and floor is also two other factors for CBM occurrence, which has broaden the ideas of occurrence rules in this area. Based on that, the developing unit is divided, the production rules for each units are summarized, and ostacles during production are analysed and solved, which can be used to provide reference for CBM development for similar area.
