| 摘 要： | 水地质条件对煤层气的赋存，运移和生产具有重要的影响与控制作用。煤层气生产过程中，储层压力的传播主要受给水含水层的疏排类型和参数等级的影响。将华北地区石炭二叠系煤储层的水地质条件划分为以煤层本身给水为主，以煤层顶（底）板砂岩给水为主和以煤层底部石灰岩给水为主的3种疏排类型，再根据有关参数在每一类型中划分出有利，较有利和不利3个等级。寿阳韩庄目标区，平顶山八矿深部目标区和韩城板桥目标区的煤储层水地质条件分别为Ⅱ类1级，Ⅲ类2级和Ⅱ类2级。

| Abstract: | ??Hydrogeological conditions play an important influence and control role in the occurrence,migration and production of coalbed methane and the transmission of reservoir pressure in the process of coal methane production is mainly controlled by drainage type and parameter grade of water-feeding aquifer.In the paper,the hydrogeological conditions of Carboniferous-Permian coal reservoirs in North China are divided into three types,i.e.water-feeding mainly from coalbed itself,water-feeding mainly from the roof (floor) sandstone of the coalbed and water-feeding mainly from the bottom limestone of the coalbed,then three grades,i.e.excellent,medium and unfavourable grades were carved out for relevant parameters in each of the types;and the hydrogeological conditions of the coal reservoirs at Shouyang-Hanzhuang target area,Pingdingshan target area and Hancheng-Banqiao target area are classified as Grade 1 (Class ??),Grade 2 (Class ??) and Grade 2 (Class ??)respectively. |
