摘　　要：对鄂尔多斯盆地上古生界110块砂岩样品中流体包裹体进行了荧光、温度和流体势分析。系统分析表明,鄂尔多斯盆地上古生界天然气具有多阶连续性运聚特征,虽可划分6期,但应为多期充注一期成藏。各区块不断运移平衡连续成藏。不同时期流体势走向不尽相同,榆林、神木、乌审旗等地区为油气长期指向区。110 samples from Ordos upper-Paleozoic were determined with fluorescence color, temperature and paleocurrent energy. The result indicates that the nature gas of ordos upper-Paleozoic was characterized by multi continuous charge and one accumulation period. Gas and oil were migrating continually. Different period has different paleocurrent energy direction, Yulin, Shenmu and Wushenqi are long-time accumulation areas.
