摘要
本文总结概括和评述了注入CO_2强化煤层气采收率技术(CO_2-ECBM)的国内外研究现状、理论基础、储层条件及其对储层改造作用产生的问题。已有的理论分析与工程实践表明,向煤层中注入CO_2提高煤层气采收率技术具有巨大潜力,能够实现中国2000m以浅煤层气产量累计增产3.751×10^(12)m^3,该技术在理论和实际方面均有很广阔的应用前景,但其对储层的改造情况尚不明确,仍需要进一步研究。
The paper summarizes and reviews the research status at home and abroad,the theoretical basis,reservoir conditions,and problems caused by the reservoir reconstruction effect of CO_2 Injection technology to enhance the recovery rate of CBM（CO_2-ECBM）.The present theoretical analysis and practice shows that the CO_2-ECBM technology has great potential and it will help to the CBM production with the burial depth lower than 2000 m to accumulatively increase by 3.751 × 10^（12） m^3.This technology is of broad application prospect in both theory and practice aspects.However,the influence of reconstruction on the reservoir is still unclear and requires further research.
