摘　　要：江苏溪桥地区浅层盐城组氦气藏是典型的构造类型气藏 ,天然气富集受低幅构造控制。研究表明该地区氦气天然气资源存在较大的开发和利用前景。Located in Xiqiao town of Taixing City, central Jiangsu, shallow Yancheng Formation helium reserve is characteristic of structural natural gas deposit. In tectonic, it is distributed in an intermediate declivity zone between Cenozoic depression area of north Jiangsu and upwarped district of south Jiangsu. The enrichment of natural gas is controlled by low-range tectonics. The exploration indicates N 2 is the major composition with content of more than 56%,CH 4 and CO 2 24%～28% and 15% respectively in the total natural gas resources. Helium reaches high content of 0.013%～1.06% and highest level 1.34%, exceeding its industrial grade(>0.3%).IN fact, grade of Helium natural gas in Xiqiao has been exceed that of Weiyuan Gas field in Sichuan Province, a sole Helium base in Chian. The investigation show that the development and utilization of Helium natural gas will be of good prospect.
