摘要:
向煤层中注入CO2可以提高煤层气采收率(CO2-ECBM)。这一技术目前已在国内外得到验证。中文介绍了该技术的作用机理在于CO2与CH4在煤体内的竞争吸附过程中处于优势,能够将吸附态的CH4置换为游离态。从煤级、煤的有机显微组分、煤储层渗透率、煤基质的吸附膨胀和煤层含水性5各方面介绍了这一技术的影响因素。指出了未来需要关注的方向。
Abstract:
Coalbed methane resource in China has great potential while the coal seams suffer the drawbacks of low reservoir pressure and low permeability. It has been proved that injecting CO2 into coal seams would enhance the coalbed methane recovery(CO2-ECBM). The mechanism of this technique depends on the stronger adsorption ability of CO2 compared with CH4 which makes CO2 could displace the adsorbed CH4 in the coal matrix. This paper reviews some aspects like coal rank, macerals of coal, reservoir permeability, adsorption-induced volume swelling of coal and moisture content of coal to discuss the influencing factors of CO2-ECBM technique. At last, this paper points out some problems to which we should pay more attention in the future.
