摘　　要：六盘水地区的13个含煤盆地具有丰富的天然气资源；天然气主要储集于煤岩及致密砂岩之中；发育两套大的生储盖组合；多种圈闭类型并存；保存条件较好。综合上述特征分析评价表明：亦资孔、格木底、岩脚盆地为Ⅰ类天然气远景区；六枝、郎岱盆地为Ⅱ类天然气远景区；其余8个盆地为Ⅲ类天然气远景区。There are 13 coal basins abundant in natural gas in the Liupanshui area of western Guizhou. The natural gas was largely found to be concentrated in the coal-measures unit and tight sandstones. Based on the development in two tyPes of traps formed by a set of source, reservoir and cover assemblages, three groups of basins potential for natural gas in this area are preferentially ranked as the following, 1 ) the basins of Yizikong, Gemudi and Yanjiao as the first target, 2) the Liuzhi and Langdai basins as the second and 3) the eight remnants as the third.
