Analyses on hydrogeological conditions for the development of coalbed methane in Hegang coal field

    摘要
  • 摘要: 鹤岗煤田煤层发育层数多、厚度大,煤层气开发具有一定潜力。通过对鹤岗煤田区域水文地质特征以及地下水动态的研究,认为鹤岗煤田水文地质条件复杂,煤系含水层补给、径流条件较好,会影响煤层气开发气井产能,而地下水的存在又可使排水作业更加有效。

     

    Abstract: Hegang coal field is characterised by its numerous coal seams,thick depths and large potential for coalbed methane(CBM)development.By study of the regional hydrogeological conditions and its dynamic,the author thinks that hydrogeological conditions of coal measures is complex with the enough supply of water and the active flow,which effects the CBM production rate.On the other hand,the occurrence of underground water is useful for the drainage of CBM well.
