【摘要】 煤层气自生成以来发生的组分分馏和同位素分馏,指示了煤层气成藏过程,这使得煤层气富集区预测成为可能。基于近年来国内外文献,将煤层气分馏划分为成因分馏和运移分馏两大类,并对各种分馏效应的研究进展情况进行了系统述评。同时论述了煤层气分馏效应的地质及工程应用现状,认为进一步探讨矿物在煤层气热解—裂解分馏中的作用和效应,培育能适应较高温度和压力且能高效利用CO2生成生物CH4的优良菌种,建立多种分馏效应共存的煤层气分馏综合效应模型,是近期本领域研究应努力的方向。更多还原

【Abstract】 Fractionation of the components and isotopes in coalbed gas since the generation of gas indicates the process of coalbed gas reservoir formation,and makes it possible to predict the occurrence of coalbed methane accumulated areas. Based on the representative publications in recent years,the authors classified the coalbed gas fractionation into the genetic and migrated ones and systematically reviewed the advances on the research of various coalbed gas fractionations. At one time,the fractionated effects both in geological and engineering applications reviewed,and aspects that should be further discussed were suggested,including the actions and effects of minerals during coalbed gas pyrogenation and cracking,the cultivation of superior fungal strains that can utilize carbon dioxide to generate biomethane under higher temperature and pressure,and the establishment of the comprehensive coalbed gas fractionated model.更多还原
