煤层气/页岩气地面集输技术及其对比分析

Surface Gathering and Transportation Technologies of Coalbed Methane and Shale Gas and Their Comparison Analysis

煤层气/页岩气作为优质、高效、清洁的非常规天然气能源,在能源消费中的地位逐渐提高,已经成为世界上油气资源开发的重要方向。相对于常规天然气,煤层气/页岩气地面集输具有非常规特性。近十几年来,国内外对煤层气/页岩气的开发,积累了丰富的开采与集输经验。从集输工艺、井场工艺、集输管网及水处理系统等方面,对国内外煤层气/页岩气地面集输技术进行了系统地总结,并对其进行了对比分析,为煤层气/页岩气的地面集输提供借鉴。

As a high quality, efficient and clean unconventional gas energy, coalbed methane （CBM）/shale gas has been increasingly popular in energy consumption and become important branch in world＇s oil and gas exploitation. Compared with the conventional gas, coalbed methane/shale gas has unconventional characteristics in the surface gathering and transportation. Over the past decade, rich experience about the surface gathering and transportation of coalbed methane/shale gas has been accumulated in development process of coalbed methane/shale gas at home and abroad. In this paper, the surface gathering and transportation technologies of coalbed methane/shale gas were systematically categorized and compared from the aspects of gathering process, well field process, pipeline network arrangement and produced water treatment.
