摘　　要：从煤储层特性分析入手 ,讨论了现有煤层气井增产技术的不足 ,阐述了用特殊的羽状水平井来提高煤层气单井产量的有利条件。并通过室内实验和研究 ,介绍了煤层气定向羽状水平井的设计方案、钻井关键技术和主要工具结构原理 ,提出了在国内现有技术与装备条件下相应的实施方案和建议。Based on analysis of coal-bed reservoir characteristics,the article discusses the shortcomings of the existing stimulating techniques and elaborates the advantages of using special pinnate horizontal drilling to improve the single well production of coal-bed gas. With in-house experiment and study,the design program of pinnate horizontal directional drilling for coal-bed gas,the key drilling techniques,and the mechanical structure principle of main tools are introduced. According to the domestic current techniques and facilities,the corresponding work schemes and proposals are also put forward. The above-mentioned techniques have the actual application value on development of coal-bed gas in China.
