摘　　要：基于对国内外近年来有代表性的学术论著分析,从煤储层描述与评价、储层非均质性、储层研究的试验和测试手段、煤储层多相介质耦合特征及渗透率预测、产能过程相渗变化及预测模型、煤层气储层排采试验动态和产能影响因素分析等6个方面,有重点地综述了煤层气储层地质与动态评价研究的新进展,并指出储层动态变化条件下的多相介质耦合特征和渗透率预测,不同地质背景下的储层渗透率动态预测,全方位、多学科的储层动态渗透率预测,构建定量-半定量的煤储层动态评价和预测体系将是今后储层地质和动态评价研究领域的发展趋势。Based on the analysis on the representative academic papers issued at home and abroad in the recent years,the paper stressed the introduction on the new progress of the study on the coal bed methane reservoir geology and dynamic evaluation from the view of the coal bed methane reservoir description and evaluation,the reservoir nonhomogeneity,the experiment and test means of the reservoir study,the multi phases medium coupling features of the coal bed methane reservoir and the permeability prediction,the phase permeability variation during the energy production process and the prediction model,the analysis on the dynamic and energy production influence factors of the coal bed methane reservoir drainage experiment.The paper pointed out that the multi phase medium coupling features and the permeability prediction under the condition of the reservoir dynamic variation,the reservoir permeability dynamic prediction under the different geological background,the full direction and multi sciences dynamic permeability prediction of the reservoir,the quantitative and semi quantitative reservoir dynamic evaluation and prediction system to be build would be the development tendency for the future reservoir geology and dynamic evaluation study.
