运用ＰＲＡ盆地模拟软件，对准噶尔盆地南缘进行了地史、热史、生排烃史模拟和资源量计算。结果表明南缘蕴藏有丰富的油气资源，中、下侏罗统煤岩是最主要的烃源岩，形成的气资源量占总资源量的４５４％在此基础上，结合不同区带的油气资源量综合评价，认为南缘的第三排、第二排构造带是寻找煤成气的最有利区带
Using PRA basin simulation software, the geo - history, thermal history, hydrocarbon generation and expulsion history simulation and resource calculation were carried out on the southern margin of Junggar Basin. The results show that the southern margin is rich in oil and gas resources, and the Middle and Lower Jurassic coal rocks are the most important source rocks, forming 45.4% of the total resources. Based on this, combining different areas Comprehensive assessment of the amount of oil and gas resources in the belt shows that the third row and the second row of structural belt in the southern margin are the most favorable zones for finding coal-formed gas
