中文摘要：
在系统采集样品的基础上，通过对煤样的煤质、煤岩显微组分、煤相、煤岩显微裂隙分析及孔隙度和压汞孔隙结构测试，研究了鄂尔多斯盆地西部的煤层气储层物性特征，并采用多层次模糊数学评价方法，预测了煤层气资源分布的有利区。结果表明，该区侏罗系煤储层具有较强的生气潜力和储气能力，孔隙系统具双峰分布特点，以微孔-小孔和大孔为主，其中二道岭-汝箕沟地区具备“小而肥”的资源优势，是该区煤层气勘探开发的最有利目标区。
英文摘要：
On the basis of systemic sample collection, by analyzing macerals , micro-fracture, facies, quality and mercury injection test on coal samples, the authors systematically studied the physical characteristics of Jurassic coal bed methane reservoirs in western Ordos basin. And the favorable area was calculated using multi-level fuzzy evaluation method. The results show that the Jurassic coal bed methane （CBM） reservoir in western Ordos basin has great gas potential, and its pore system has bimodal distribution, and is dominated by micropores, mini pores and macropores. The Erdaoling-Rujigou region is considered as the most favorable target area for CBM development.
