煤层气的集输技术研究

针对煤层气的基本理化性质及存在状态,对当前国内外煤层气地面集输相关技术进行了理论研究,概述了煤层气的定义与形成过程、国内煤层气的分布特点与开发技术。对当前常用的3种集气工艺进行了综述,并将多种煤层气运输技术的优缺点进行了简单对比。重点介绍了煤层气的管道输送、液化储运、固态储运等3种方法。并指出,由于煤层气液化储运法克服了长途铺设管线法耗资大、覆盖地区有限,且不具备储存和调峰能力的缺点,因而具有良好的应用和发展前景。

Gathering and Transporting Technology of Coal Bed Methane (CBM)

According to the basic physical and chemical properties and the existence of the CBM,a theoretical study is made of the current domestic and international coal-bed methane ground gathering technologies.The definition and formation of coal-bed methane and the characteristic coal-bed methane distribution and development technology in China is overviewed.Three kinds of gas gathering processes are reviewed.Besides,a variety of advantages and disadvantages of coal-bed methane transportation technology is compared with the focus on coal-bed methane pipeline,liquefied storage and transportation,solid-state storage and transportation methods.The paper points out that due to coal-bed methane liquefaction storage method that helps overcome the cost of long-distance pipeline laying large coverage area is limited,without storage and peaking capacity shortcomings,this technology has a good application and development prospect.
