塔里木盆地寒武系页岩气潜力分析

Geologic Potential Analysis of Shale Gas in Tarim Basin

我国页岩气勘探程度低,资源潜力巨大,前景良好,同时面临政策缺位、技术落后等挑战。通过对塔里木盆地巴楚—阿瓦提、满东2个地区的寒武系烃源岩特征的研究,其烃源岩的总厚度达到360 m,有机碳含量(TOC)达到5.35%,Ro达到2.35%,因此,塔里木盆地页岩气有很好的前景。

There are abundant unconventional natural gas resources（UCRs） in China. Totally, lower exploration degree of UCRs means good development potentials in China, at the same time, development of UCRs in China faces some challenges including shortage of incentive policies and lagging technologies. In this article, Cambrian hydrocarbon source rock characteristics of BachuAwati and Mandong areas in Tarim basin were studied. The results show that total thickness of source rocks reaches 360 m, organic carbon content（TOC） reaches 2.35%, Ro reaches 2.35%. Therefore, Tarim Basin shale gas has a good prospect.
