煤层气开发的水文地质问题

Hydrogeological problems in coalbed gesexploitation

本文在分析国内外煤层气开发研究现状与问题的基础上，阐述了控制煤层气产能的地质因素。其中，水文地质条件研究是整个煤层气勘探开发中的一个重要部分。通过煤层气水文地质基本关系的分析，提出了我国煤层气开发的水文地质研究问题。

On the basis of analysis of the present condition and problems in the study on coalbed gas exploitation at home and abroad,geological factors controlling the output of coalbed gas are stated in this paper.Among them the study on hydrogeological conditions is an important component in the whole process of exploration and exploitation of coalbed gas.By analyzing the basic hydrogeological situation of coalbed gas,hydrogeological problems to be studied for coalbed gas exploitation in China are raised.
