新集矿区煤层气的生储特征及示范开发

根据已有的勘探资料,利用气体地球化学、煤岩有机化学、煤变质程度和构造演化史等分析手段,对新集矿区煤层气的生成条件、保存演化史及保存条件等煤储层特征,进行了较系统地研究。在此基础上,选用水力压裂增产强化措施,采用先进的压裂软件进行优化设计,在示范区取得了国内同等地质条件下煤层气开发产气量最大,稳产时间最长的成果。 

CBM generation and reserve characteristics and its pilot development in Xinji Mining Area

To systematically understand the coal reservoir characteristics in Xinji Mining Area,the used study methods involve in exploration data analysis,gas geochemical analysis,coal petrographic study,coal rank and techtonic evolution analysis.The study is focuses on CBM generation conditions,reserve evolution history and reserve conditions,as well as coal reservoir characteristics.The study results are used as foundations for further development in this area.Based on the results the pilot project adopted the hydro fracturing treatments and advanced software,resulting in largest CBM gas production and longest stable production time comparing with the same conditions' coal reservoir in other areas.
