摘　　要：由于煤层气田"低产、低压、低渗"和地区地形复杂,相对高差较大的特点,不同程度地加大了工程设计与建设的难度,开采与输送成本相当较高。通过对煤层气田集输工艺特点的详尽分析和多年的现场试验及技术改进,坚持地面与地下充分结合的原则,基本形成了一套先进合理、经济适用并符合中国煤层气特点的煤层气田地面集输技术。在此,介绍了在煤层气田地面建设中所采用的"枝上枝状管网,阀组布站、手动/自动轮换计量,数据无线传输,阀组发电,压缩机余热采暖,站场集中增压"等新技术。新技术的应用取消了传统技术中需要建设的无数个有人值守的站,极大地简化了流程,为煤层气田的有效开发提供了借鉴。Given the low producitivity, low pressure, low permeation and the complicated geography as well as the large relative height difference of CBM fields, it is more difficult to conduct engineering design and constuction and the costs of mining and transport are very high. An advanced, reasonable and cost- effective surface gathering and transmission technology that can meet the features of the CBM in China has been developed based on the detailed analysis of the characteristics of CBM gathering and transmission processes, years of on-site tests and technical improvements and the principle of thorough combination of surface and underground technologies. In this thesis, various new technologies used in the surface con- struction of CBM fields will be introduced, such as branch-on-branch network, valve group stations, manual/automatic rotation measurement, wireless data transmission, valve group generation, heating with compressor waste heat and centralized pressurization of stations. The new technologies have eliminated the construction of the great number of stations requiring manual operations, significantly simplified the process and provided references for the effective development of CBM fields.
