摘要： 本文根据准噶尔盆地760个测温点资料,结合盆地构造演化过程对盆地地热场特征及其与油气的关系进行了探讨。认为准噶尔盆地是一个较冷的盆地,地热场偏低,而且经源岩偏老,以致生油气门限潭度偏大,给勘探工作遭成一定困难。

Abstract: The characteristics of geothermal field versus hydrocarbon occurrences in Junggar Basin studied in this paper are based on 760 heatflow measurements combined with basin tectonic evolution analysis. It is considered that the Jung- gar Basin is a relatively cold basin with les intense geothermal field. The source rocks are older and the depth of gene- rating hydrocarbon threshold is deeper, which results in certain difficulty for petroleum exploration.

Key words: Junggar Basin, geothermal gradient, geothermal field, geothermal heat flow value, vitrinite reflectance
