摘要
针对煤岩气水相对渗透率对煤层气开发地质研究领域的重要作用,基于系统的文献调研,对煤岩气水相对渗透率确定方法、国内外煤岩气水相对渗透率研究进展、影响因素与试验限制条件进行了总结和分析。针对目前各类煤层气的相对渗透率确定方法的局限性和研究的滞后性,指出影响煤岩气水相对渗透率的煤岩物性因素和制约煤岩气水相对渗透率研究的试验条件。最后,提出了未来煤岩气水相对渗透率领域需要加强研究的方面,以期为未来煤层气高效开发提供相关参考。
According to the important effects of gas-water relative permeability of coal and rock in the field of coalbed methane develop-ment geology,based on systematic literatures review,methods of gas-water relative permeability of coal and rock determination,the re-search progress both at home and abroad,influencing factors and experimental conditions were summarized and analyzed in this paper.In view of limitations in various methods and hysteretic research status,the influencing factors and restricting experimental conditions for gas-water relative permeability of coal and rock were pointed out.Besides,some important directions for further studies of gas-water relative permeability of coal and rock were proposed aiming at providing reference information for coalbed methane effective development in future.
