HYDROGEOLOGY OF EXPLORATION AND DEVELOPMENT PILOT AREA FOR COALBED METHANE IN LIULIN

摘要: 柳林煤层气试验区区域水文地质条件简单,围岩含水层是煤层水的主要来源,4、8号煤层可动水含水饱和度为39%,裂隙及割理是重力水赋存的储集空间和运移通道。8号煤层的含水性、水活跃程度和产水量强于4、5号煤层。采用斯蒂夫离子图解划分采出水的煤层属性和煤层合采时的主产水层,煤层水属正常-略超压状态。水力坡度较陡的区域是部署开发井的有利地带。

Abstract: The regional hydrogeological conditions are simple in Liulin pilot area.The adjoining aquifers are the main source of coalbed water,and the saturability of movable water reaches 30% in No.4 and 8 coal seams.The fractures and cleats are the storage space and migration channel for free water.The waterbearing behavior,water activity and water yield in No.8 seam are stronger than those of No.4 and 5 seams.The seam from which the water is pumped and the main water-produced layer during multi-seam mining are identified using Stiff ion diagram.The status of seam water are normal to over-pressure a little.The regions with steeper hydraulic gradient are the favorable ones to set the developing wells.
