煤层气开发和综合利用面临许多现实的技术问题需要研究解决。笔者从煤层气开发工程存在的问题出发，提出了一些新的煤层气开发关键技术，如煤层气高效完井和高效增产技术等。从中国能源结构、天然气市场消耗量和煤层气开发实用技术等方面综合分析煤层气开发对策，指出今后煤层气开发必须将实用技术攻关和争取国家鼓励政策结合起来。煤层气综合利用技术已在小范围内得以应用，如用作民用燃料、用于电厂发电。煤层气开发利用还处于初期阶段，但中国煤层气市场前景广阔。

Key Techniques and Integrative Utilization of Coal-bed Gas Development in China

Development and integrative utilization of coal-bed gas faces many concrete technical problems to study and solve. Aiming to the problems of coal-bed gas development,some new key techniques are proposed for coal-bed gas development,such as the techniques of efficient well completion and efficient stimulation,etc. Based on the integrative analysis of Chinese energy structure,market consumption quantity of natural gas,and applicable techniques,it is pointed out that solving technical problems must be combined with urging preferential policies from the government for coal-bed gas development. Now,integrative utilization of coal-bed gas has been applied in a small scale,such as residential fuel and power generation. Although it is at beginning stage,development and utilization of coal-bed gas has bright prospect in China.
